    DB:5.13:Size Of Hot Spare Slices sx




    Hi
    Solstice DiskSuite 4.2.1 User's Guide section on 'How to Associate a Hot Spare Pool (DiskSuite Tool)' states "The hot spare pool should have slices the same size or larger than the submirrors in the mirror, or the slices in the RAID5 metadevice."
    Is this true?
    I understood that if I have 8Gb submirrors made up of 4 x 2Gb slices then my Hot Spare slices need only be 2Gb, whereas the documentation suggests that Hot Spare slices should be 8Gb!?

    DB:5.13:Size Of Hot Spare Slices sx

    Hi

    I think this depends on how the metadevice has been configured. If your metamirror of 8Gb is made up of 4 metadevices ( each 2Gb ) then the minimum size of your hotspare need only be 2Gb. Since a disk failure would cause one 2Gb component to fail and this would be replaced by your 2Gb hotspare device ( assuming each slice is on a different disk).
    However if your 8Gb metamirror was created from 4 slices on the same disk you're going to have to replace the whole metadevice, in this case 8Gb.

    DB:3.46:Export Slices To Smaller Size ? d8





    I know I'm wasting some time on this question, I could do a work around, I have a bit of time to spare

    Is it possible to export slices from Ps as smaller size ? I have two slices which are both 2048 pixels, I want to save them both out smaller for the web in one shot, possible or dreaming ?

    The list is larger then I saw previously. There is a strong possibility I will upgrade to CC very soon. Anything else CC has that may be of a positive surprise ?

    DB:3.34:Dmx "Enable Deferred Service" Option fp




    We have received a request from EMC to enable the "Enable Deferred Service" option on a pair of mid-size DMX-4 arrays we manage on behalf of one of our customers. This would be in conjunction with enabling the "Permanent Hot Spare" feature.

    I may be misunderstanding the process, but while there could be benefits with the permanent hot spare feature, I am struggling to see many from allowing deferred service, especially from a customer perspective.

    If a disk has failed or been pro-actively spared - decreasing the number of available hot spare drives, then isn't it best that the drive be replaced ASAP - returning the array to its maximum resiliency, rather than waiting until the available hot spare count (for a particular drive type) equals 0 ?

    Apologies if this has been discussed previously, but are other sites allowing EMC to enable the 'deferred service' option?
    Any/all comments and clarifications welcomed.




    DB:3.34:Dmx "Enable Deferred Service" Option fp


    Thanks Steve I believe that I understand the process.

    However I am not comfortable with an activity (replace the failed disks) being triggered only after a resource has been completely depleted. Particularly since the disk replacement could then be delayed by factors completely outside EMC's controll - I am thinking of an 8 hour traffic jam on the main northern freeway out of here earlier this week...

    I have a 4 disks ina pool setup as raid 10. I have a 5 disk in the device not assigned to any pool and the global configuration set to enalbe Hot Spares. I see Hot spares is enabled in the configuration. Is that all I have to do? the manual is a little vauge on this. I dont add the drive to the pool? I see that I could. Im assuming it will only use the same size/speed drives for the appropriate pools? So if I added anotehr pool of say smaller drives and an other spare it would know which spare belonged where?

    DB:3.32:Px12-400r Hot Spare 1c

    Hellotopkatz

    Engineering confirmed that the feature will use the first available hot spare, regardless of the model, for a disk failure in a storage pool.

    The one exception is that the feature will differentiate between the different capacities of thedisks if the storage pools have different sized disks. The feature will try to use a drive that has a matching capacity.

    Hi,

    i have one poweredge T110 II with PERC S100 and windows server 2012 fdn and my raid 1 array is degraded but on openmanage dont have any option to rebuild and if i try assign drive to hotspare he tell me Storage Management only displays those disks that can be used as a hot spare. There are currently no disks that are available, large enough, or of the correct type to be used as a hot spare for this virtual disk.

    but the 2 drives have same size and are original from dell server.

    i already try put out drive from server and clean it with diskpart but without success. error persist. bios options on boot isnt useful too.

    why is so difficult rebuild array with this controller? i need backup and reinstal all again to repair raid?

    DB:3.17:Perc S100 Raid1 Cant Rebuild Ou Assign Hotspare x3


    Hello jestima

    The S100 is a driver based RAID controller. Server 2012 is not a supported operating system for the S100. We do not have a driver for Windows Server 2012 on that controller, and since it is a driver based controller it depends heavily on the driver. Using a generic controller driver or the wrong controller driver will result in odd behavior.

    I would suggest that you backup your data before doing anything else on the system. My only suggestion would be to update the system BIOS. The S100 is part of the system board chipset, so updating the system BIOS will update the S100. I doubt that will fix your issue, but it is worth a try. If this is a production system then you should not be running incompatible hardware/software. You are at high risk of data loss in your current configuration.

    I would recommend that you either install a supported operating system or get a controller that is compatible with server 2012. The H200 or S300 controllers are validated for server 2012 and have drivers available for download.

    Thanks

    DB:3.08:Removing Disk From Hot Spare 33



    Hi,

    Could some one suggest, how can we remove one single disk from hot spare and add it to unconfigured space.

    Currently hot spare has 2 disks.

    Thanks in advance.

    DB:3.08:Removing Disk From Hot Spare 33


    You can follow these steps to remove any disks from Hotspare pool.

    1. Click on System Storage Pools.

    2. Select Hot Spare Pool and click on Configure Disks button at the bottom.

    3. In the Disk Configuration wizard it displays the type of disks available in the system and recommended number of drives for each type (with a star). Depending on how many hotspare disks you want in a particular type of disks you can increase or decrease the number in drop down menu. Following are examples with different scenario:

    Example #1

    You have already configured 3 SAS 300GB disks as hotspares and want to remove 2 disks so that you can use for other purpose, select 1 in the drop down menu. This will remove 2 disks and maintain 1 disk in the Hot Spare Pool.

    Example #2

    You have already defined 1 Hot Spare disk for SAS disks and want to setup one more for NL-SAS disks. Go to same Configure Disks wizard as above, choose 1 in the drop down menu for NLSAS disk type without altering any other disk types.

    Example #3

    You have defined Hot Spare for different disk types, you dont want to have a hot spare anymore and want to remove them.

    Go to same Configure Disks wizard as above, choose 0 for all disk types and finish.

    This happened a while back, and the metastat output has looked like this ever since. Can someone please clarify for me whether 'resyncing' means the failed device (c1t3d0) or the hot spare (c1t2d0)?

    The c1t3d0 drive is still showing as 'online' in ssmadmin, so I think its only suffered a 'soft' error. I'm reluctant to pull either drive until I'm sure of which SVM is currently using.

    Alternatively any suggestions of the likely outcome of simply running 'metareplace -e d100 c1t3d0s6' if the drive were actually faulty would be welcome.

    It's sometimes easier to modify that than to get the OBP path from Solaris.

    DB:3.00:Pe2650 - Perc 4/Dc - Revert Physical Disk To Hot Spare mm


    I've got 5 HD drives in my PE2650 backplane in RAID 5 config all on one virtual disk.
    I added my hot spare disk to the virtual disk to increase the size.

    Can I revert that last disk back to a hot spare? Hope so...

    I've got the latest bios and driver for the PERC 4/DC, the latest system bios and OMSA 5.2.0.

     

    thx 

    DB:3.00:Pe2650 - Perc 4/Dc - Revert Physical Disk To Hot Spare mm


    When a disk fails the server keeps running only without the parity. 

    Once you see/know that a disk has failed, you take it offline, replace it with the spare disk you have ready and it automatically starts rebuilding.

     

    With a hotspare the rebuilding starts without having to replace a disk. All you have to do is to replace the bad disk with a fresh one and assign it as a hotspare again.

     

    The amount of time depends on how long it takes before you know you have a bad disk. If you don't get a warning and you never take a look at your servers than it can take a while before you know something is wrong.

    DB:2.99:Zpool With Hot Spare - Which Is Not "Hot" At All (Not Taking Over Autom.) zs


    Hello,

    I build a mirror of two and a hot spare

    zpool create data mirror tmp1 tmp2 spare tmp3

    the tmp's are local files

    after offlining tmp1 there is no message about the degraded state of the pool in /var/adm/message

    and

    there is no automatic takeover of the hot spare tmp3

    How so?

    DB:2.99:Zpool With Hot Spare - Which Is Not "Hot" At All (Not Taking Over Autom.) zs

    Try that with real disks. Using local files is not a good way to simulate disks failing or being removed.

    I don't know the specifics but I've investigated it a little bit some time ago. It seems the software layer is not telling ZFS what has happened and if there is no activity, it won't know until it tries to use the files. You can try to simulate some heavy read/write activity and see if it detects the 'failure'.

    But again, testing with real hardware is the proper way to see how hot spares work (and they do work, just ask my 400+ systems). The local files are nothing but a way to play with it easily, not to be used in production.

In my case i have a 400G 10k hot spare drive that will spare either for 400g 10k drives or 146g 15k drives. What concerns me is that last line that says that 146 drives have 0 spares. Is it purely cosmetic where in reality if a 146g goes bad, 400g would spare for it ? It's all handled by the back-end ..Celerra has nothing to do with spare selection ?

    i zoom in and the size and position in the AI file is correcti zoom in in the "save for web devices..." export dialog and the slices are misaligned or not even the right height (extra transparent pixels etc.)the output PNGs match the export slices dialog and not those in the document and are all off (with extra pixels or height 1px off)

    i tried all i could think of, such as align to pixel grid, recreating the slices, and all such things to no effect. has anyone ever encountered this and can suggest a solution?

    In Photoshop, you can create a slice that is the size of the document, set it to no image and send it to back. Any implicit slices that are created around your set of exlicit slices contained in the boundries of this large slice, also have a setting of no image.

    Is there a way to accomplish this in Illustrator without having to explicit set to no image any new implicit slices that are created? When creating a large slice in Illustrator, there is no way to send it to back and in the instance where it appears to be display in back of the other slices, it is not possible to select the other slices regardless of them appearing to be in front of this "root no image slice"

    Hi,

    We have a Se6910 (san) connected to an e10k with 2 domains and we are using Disksuite 4.2.1

    On both domains we have one metadevice which is in state Errored.
    This metadevice is a soft partition.
    Below is the output of metastat of the softpartion (d180) and the stripe set (d80)
    How can we get this softpartition to OK state?

    Thanks for your help.

    My interlace value is 64 blocks or 64k which make my stripe set size 4*64k or 256k.

    Do you agree?Probably correct. Clarify with the vendor if there's confusion on the terminology.

    Also what is the disadvantage of using geometric reads? The documentation only mentions possible performance improvments and no possible loses.Geometric reads map a file offset to a device. Not all read patterns are sequential. You could have a file where only particular offsets are read. Those offsets might always map to the same device. In that case, you'd be reducing your read throughput by concentrating all reads on the same deviceq. A round-robin read will always use all available mirrors.

    DB:2.86:Replacing A Faulty Drive With A Hot Spare Physically k8



    Hi Folks,

    I am in a situation where in I need to replace a faulty disk on one of the Celerra CX-480s (currently support contract has expired, so need to do it myself )

    The options that I have is that I have a disk in hot spare pool which is of the same size and RPM.

    I am thinking of removing disk from the hot spare physically and adding it on the slot where the faulty one resides.

    What all things should I take care of while doing this?

    Are there any specific steps that needs to be followed?

    Any help will be appreciated

    Seeing though that over 3 months have elapsed since you posted, maybe you have already found the answer (possibly opened up a ticket with support)? If so, once relocated, consider sharing the resolution and also marking the question as "Answered" so that it can help others that have the same question. If not, once relocated, it will then have more visibility by the community of dedicated customers, partners, and EMC employees that are eager to assist.

    I'm thinking you have since taken care of it, but if you are unable to obtain a new drive and need to repurpose one of the equivalent hot spares, then what you should do first before removing the drive is to unbind it. As a hot spare, this would mean unbinding the private LUN as well as the RAID Group assignment. In Unisphere, under the "Hot Spares" view, you have the option of "Delete" which would accomplish the same.

    DB:2.84:Questions About Proactive Hot Spare Copy And Swapping Drives In Cx320 3z



    We have a locally owned spare SATA drive for a CX320 that is to be used for a replacement drive when there is time gap between a drive going bad and the maintenance vendor providing a replacement. We recently used this spare drive. Then when we got the replacement, we did a proactive hot spare copy of this locally owned spare in preparation of swapping in the replacement. We got these messages from the locally owned spare and the hot spare - we don't know if these messages were when the proactive hot spare copy ended:

    Enclosure 1 Disk 13 Description Unit Shutdown

    Array Enclosure (Bus 0 Enclosure) is faulted. Servers may have lost access to disk drives in this enclosure.

    Device Enclosure 6 Disk 0 Description Disk (Bus 0 Enclosure 6 Disk 0) is faulted.

    Storage Array Faulted Bus 0 Enclosure 6 : Faulted Bus 0 Enclosure 6 Disk 0 : Removed.

    Storage Array Faulted Bus 0 Enclosure 6 : Faulted Bus 0 Enclosure 6 Disk 0 : Removed.

    Enclosure 6 Disk 0 Description CRU Powered Down

    Description Disk (Bus 0 Enclosure 6 Disk 0) failed or was physically removed.

    SPA Device Enclosure 1 Disk 13 Description Unit Shutdown.

    Enclosure 1 Disk 13 was where the proactive hot spare copy was being written.

    Enclosure 6 Disk 0 was where the locally owned spare SATA drive was.

    Are these the messages I would get when the proactive hot spare copy completed?

    Now the locally owned spare has been replaced with the vendor provided disk.

    My other questions are: anyway to know that the locally owned spare is still good? anyway to initialize this disk so while its sitting waiting for its next use we know there is no data on it?

    Appreciating any experience, advice, etc.

    DB:2.84:Questions About Proactive Hot Spare Copy And Swapping Drives In Cx320 3z


    The drive should be able to be used as it is. The way flare works is if a drive drops ready it automatically rebuilt when it brough tready or when a new one is inserted. there is a command to format a drive back to how it ships orginally but you have to know the engineering password. If done wrong you will wipe data as it writes zeros over the drive. The only thing it buys you is a faster lun bind so its not really worth doing.

    DB:2.81:Sas 6/Ir Poweredge T710 - Predicted Drive Failure 3s


    I wanted to check the procedure for replacing one drive and synchronising the array. I am worried

    I have identified the drive to replace through Dell OMSA and made it blink

    There is no hot spare on this machine.

    How does this sound:

    Remove the drive and replace it with spare one of same size (unfortunately the spare is not blank, and it was used on a previous array).

    Turn off the server.

    On reboot press Ctrl-C and enter Raid Properties, View existing array, Manage array

    Synchronise array.

    Wait while the array synchronises.

    Many thanks

    DB:2.81:Sas 6/Ir Poweredge T710 - Predicted Drive Failure 3s


    Gus,

    You will need to force that Pred Fail drive offline from the array before removing. Then insert the replacement drive and then within the controller the new drive should show as a Foreign. Clear the foreign and then the drive should show as Ready. You can then assign as Global Hotspare and it should rebuild.

    Let me know how it goes.

    I have:

    SunOS kite 5.9 Generic_117171-12 sun4u sparc SUNW,Ultra-250

    installed and working as production system. On Friday, it appeared to have a disk issue and all the services kept shutting down soon after being restarted (several times). I cranked up all the logging to debug, and could not find anything that would indicate why the services would keep shutting down. I could not find any issues with prtdiag -v. When the machine was rebooted, the prompt for fsck came up for disk maintainence. I tried to run fsck against the disks that were affected. The two slices I tried belong to a mirror (d8) that I have setup. I get the following error messages trying to run fsck:

    At the time, I got a "Needs Maintanenc" message for the mirror when the system boots. But when I do prtdiag -v, the disks show no errors.

    The ims 6.2 would not stay running no matter what I tried. I finally deattached d28 from d8. I tried to run a fsck but still recieved the same message as provided earlier. I reattached d28 to the d8 mirror and let it start to resync. After the resync was done, I restarted the ims 6.2 services and all seems okay now.

    What would cause this type of behavior? Should the disks be replaced? I am not sure were to go on this one. I have search the syslog, messages, ims logs in debug, etc and can not find why ims 6.2 would shut itself down like that. Any suggestoins would be appriceated.

    DB:2.81:What Are The Ramifications Of Disabling Virtual Hot Spare? 9k



    Hello,

    What are the ramifications of disabling Virtual Hot Spare (VHS) on the Isilon cluster?

    DB:2.81:What Are The Ramifications Of Disabling Virtual Hot Spare? 9k


    If you disabled VHS, you will gain a bit of disk space but by doing so you open yourself up to a possibility of a most serious nature.

    If you have VHS disabled and the cluster fills 100% full, through legitimate ingest or error. Jobs may stop, a failed disk will not have room to smartfail out. You may not be able to even add a new empty node to alleviate this condition. In short it is a very bad idea, and not worth the small gain IMO.

    Sun support confirmed that you can have the 2 halfs of the mirror with different interlace sizes, this obviously is not the optimum setup, but will allow me to detach d61 and recreate with correct interlace size, reattach d61 and let it resync, then detach d62 and recreate with correct interlace size and finally reattach d62 and let that resync

    DB:2.75:Size Of Slices In A Pie Chart 9k



    Hello all:

    I am wondering if you can ask SAS to size the slices in a pie chart according to the percentage but also display the mean sumvar statistics. For example, I can do

    proc gchart data=survey;

    pie role / sumvar=score

    percent=inside

    value=arrow

    descending

    slice=arrow

    coutline=black

    noheading;

    run;

    quit;

    In this case, the slices are proportional to the % of role and sum of scores are displayed. What I really want is to display is the mean of scores. However when I add

    type=mean

    The size of slices become proportional to mean(score) instead of percentage now. How can I fix this?

    Thanks,

    Peter

    If you want to use swf files and create hotspots then you
    have to import

    If not then use a gif file of the map and add hotspots in
    Dreamweaver.
    That is quite easy actually -

    Your swf file is 96kb right now. A gif file of the dimensions
    you have
    showing on your page will be smaller.

So IMHO you're better of with a SATA HS invoked than running in degraded mode if you love your data !What would perform better ?- degraded Raid5 Raid Group (for example 4 x FC + 1 x SATA HS invoked)- degraded Raid5 Raid Group without any HS invokedThe first option certainly is safer !

    DB:2.74:Xserve Raid Windows Expansion Questions 18


    I have an Xserve Raid running in a Windows 2003 environment. It is fully populated with 14 400GB drives in the slots.

    I have two Raid 5 arrays (3 drives each / 1 slice per Raid) on each side with one hot spare per side. I want to expand one of the Raids with the spare.

    So it looks like this:

    AAA H BBB|CCC H DDD

    Here are my questions:

    1) How long will expanding the Raid take? Ball park? Say 10H? The Raids are full. Are the Raids accessible but slow during this period?
    2) What is the point of the Hot Spare? I dont really see any advantages to it vs a cold spare? It doesnt even save me a trip in to the office cause I cant assign it to the raid on the fly anyway.
    3) After I expand the array with the spare do I have to merge it? I have read conflicting posts.
    4) Is it correct that I will have to use a Partition tool to get the OS to see the expanded Raid size?

    Thanks for the responses.

    DB:2.74:Xserve Raid Windows Expansion Questions 18

    Thanks for the response Camelot. Sorry for the confusion.

    What I want to do is expand the hot spare drive into one of the arrays so:

    AAAABBB|CCC H DDD

    Basically I am running low on space and right now that takes precedence over the hot spare. This will not erase the data on AAA will it during the transition to AAAA? Just the hotspare which is of course empty.

    Thanks again for your help.

    DB:2.74:Raid5 Problems Solaris 10 af


    I have a V445 with 2 73GB and 6 146GB drives internal. Two of these drives (73GB) are mirrored for the operating system. The other 6 drives had been configured in a RAID5 with hot spare. I had a system failure which I believed to be related to the PCI SAS expansion card because two drives (one above the other in the system) would not return to a usable state. Throughout my attempts to solve this problem, I have replaced all hardware (including the base V445 system) and all of the drives in this RAID5 config. One of the drives has returned to normal operation, however, one drive continues to fail when I attempt to rebuild the array. This makes me believe that maybe something is wrong in the metadb or something software related instead of hardware related. Some system information is listed below. In the information below, RAID "d5" is the issue, "d1" is a StorEdge 3120. I do not currently have the hotspare (hsp000) populated, but it usually has c2t7d0s0 as the hotspare device. I can put c2t7d0s0 into the array instead of c2t3d0s0 and it will initialize fine, this only fails with c2t3d0s0. I have changed the drive and drive tray (not that I believe the tray would be a problem).

    You want to backup your virtual machines with the help of CDs but have trouble with the large files?

    Well that can be changed.

    Code: make-disk-in-cd-slices.cmd

    vmware-vdiskmanager -c -a ide -s 670Mb -t 1 cd-slices-disk.vmdk

    vmware-vdiskmanager -x 1340Mb cd-slices-disk.vmdk

    vmware-vdiskmanager -x 4020Mb cd-slices-disk.vmdk

    vmware-vdiskmanager -x 4690Mb cd-slices-disk.vmdk

    This command will create a virtual growing disk with slices that will never be larger than 670MB. If you need a disk that is larger than 4690MB you will have to add some lines. For smaller disks ... well you should be able to see the pattern.

    The command as it appears above can be used as one cmd on a Windowshost. The syntax is the same for Linux.

    DB:2.73:Should We Change The Hot Spare Disk ? 33



    One of our 300GB disk (CX4-120 System) breaks down and DELL replaces it with a 450GB FC Disk.

    We get a warning message "The storage system has no hot spares that are as large as its largest disk" from Navisphere. The hot spare disk is currently of size 300GB.

    We just wonder whether we need to replace the Hot Spare Disk with a 450GB HD (Just in case the newly replaced 450GB FC Disk fails in the future).

    Your advice is sought.

    Thanks

    DB:2.73:Should We Change The Hot Spare Disk ? 33


    you don't have any raid groups that are build out of 450G drives, all RGs are 300G drives ? If the 450G drive is a member of a raid group with 300G drives, then only 300G of space being used on the 450G drive ..so if it were to fail, 300G hot spares would spare for it just fine.

    DB:2.73:Pe2650 - Failed Drive - Hot Spare Procedure 9p


    Hi all,

    My system: 
    PE2650 running Linux (Fedora 4)
    5 drives.  Raid-5 + Hot Spare.  Drive 0 = Hot spare, Drives 1-4 = Raid 5.  Raid was configured using BIOS.

    This morning I came in with drive 3 blinking amber, and a E0d76.  The Hot Spare (drive 0) was blinking green  with the rest of the drives as the server was working, so it looks like the hot spare did its job.

    And for those of you out there debating the value of a hot spare, trust me, when it works it is the greastest thing in the world to see.

    I swapped out drive 3 with another drive off the shelf, and it is now a steady green light.  This was about 30 minutes ago. 

    So now I am wondering where to go from here.

    - Will the array rebuild to where it was?  With Drive 0 = hot spare and Drive 3 rebuilding in the Raid-5 array with the rest of the drives?

    - Is Drive 3 now the Hot Spare?  Or is it just sitting there with the server in a compromised state?

    I have all the manuals from Dell's website, and I can't find any type of procedure as to what to do now.

    Any help/advice greatly appreciated,

    Rob

    For future reference....

    On my server, the hot spare was NOT automatically enabled.

    DB:2.73:Cx3 Hot Spare Replacing Failed Drive, But No Ios Reported p8



    We have a Clariion CX3-10 system with three RAID groups.

    The first two each contain 5 disks and are configured as RAID-5. The 11th disk is configured in a separate RAID group as "Hot Spare".

    Last week one disk failed and the hot spare was initiated.

    From the NaviSphere point of view:

    - There's still a fault on the array being reported

    - But the hot spare claims to be "replacing bus 0 enclosure 0 disk 2"

    Browsing through the Navisphere interface I don't see any actions it is prompting me to do.

    At this point I -assumed- the hot spare was actively acting as a replacement for disk 2, assuring that RAID-5 redundancy was still intact.

    But now the interesting part -- We use software that reports on disk usage (IOs, cache hit, response time, etc)

    This shows that as soon as the failure was recognized, both the failing disk and the hot spare started a huge load of IO, indicating that the system was pro-actively copying all the data to the hot spare.

    But as soon as this copy was done, the hot spare became dead-silent once again.

    It is reported in the proper array (along with disk 0,1,3,4), but has not been used since. No IOs at all.

    My questions are therefore:

    Once a disk fails, and the hot-spare is initiated, should I (a) do anything else to restore full redundancy, and (b) do anything to allow the system to start using the hot-spare for actual disk IO?

    Any tips or thoughts on this issue would be appreciated.

    DB:2.73:Cx3 Hot Spare Replacing Failed Drive, But No Ios Reported p8


    Is this drive that failed a part of your Vault disk set?

    Even if it is your Vault drive that failed you'd have to replace it. If the copy to hotspare is complete, go ahead and replace the drive.

    After replacing keep that sticker on the new drive so no one pulls the vault drive.

    DB:2.73:Degraded Hot-Spare j1


    Hi, I have a PE 1500SC with a PERC 3/SC and 6 32GB SCSI disk (nr 0-4 in a in RAID 5 array, nr5 as a global hot spare). server and disks are 5.5 years old. I'm going to replace it in 6 months, but currently it holds all the company critical data. Last week disk nr0 went degraded: amber light was flasing and Openmanage marked the physical disk as degraded. Anyway the RAID array was working and the hot-spare disk was silently waiting for something to happen. As a precaution I replaced the degraded physical disk (nr 0) with a similar one that I was using as hot-spare on a PE1600 server. The PERC 3/SC RAID controller (which is using latest firmware and drivers, win 2k sbs s/o) started the reconstruction of the array and after a couple of hours all was fine: disks 1-5 working in RAID 5 and disk 0 as a global hot-spare. Today I had a look in Dell openmanage: disk 0 (the disk I replaced ) is marked as DEGRADED, Global Hot Spare. Isn't the hot spare used only in the event of a disk failure? How could it be degraded? Maybe a fault on the PERC controller or cables/connectors? Thanks Guido

    DB:2.73:Vnx Fast Vp Tiering Polices xm



    Hi,

    The latest FAST VP paper has been published, but it is still a little confusing as to how the polices work:

    Highest tier

    Initial placement should nearly always be on the highest tier as 10% of capacity is always kept free

    The coldest slices will be moved to lower tiers based on the defined schedule, but only at the expense of other Highest tier LUN slices

    Hot slices on lower tiers will be moved up based on the defined schedule

    If the size of the slices allocated to all highest tier LUNs is greater than the tier size, then no other tier priorities will ever have their slices on the highest tier - is this correct?

    Lowest tier

    Initial placement should always be on the lowest tier

    The slices will never move off the lowest tier even if they are very hot - is this correct?

    Auto-tier

    Initial placement will be to spread all slices across all the tiers based on free capacity

    The slices will never move to the highest tier if it is full with slices from highest tier priority LUNs even if the IO is much higher on the slice than those already on the highest tier - is this correct?

    The slices will moved to the appropriate tier based on activity (i.e. typically T2 or T3)

    So if you have:

    1. A LUN that needs best performance - set to Highest tier

    2. A LUN that does not need good performance - set to Lowest tier

    3. A LUN that needs good performance - set to Auto-tier

    This does mean that you could have very cold slices of the highest tier sitting on T1 or T2 storage, very hot slices of auto-tier sitting on T2 and very hot slices of lowest tier sitting on T3 - is this correct?

    I am not 100% sure about this, but it is my interpretation of the paper.

    Any comments would be much appreciated.

    Hi All

    I have a few concerns over creating Hotspare RGS

    a) If we plan to use multiple disks, then is it required to create multiple RGs and adding each of the disks to seperate RGs or a single RGs with multiple disks added to them is enough?b) After creating a RG as hot spare, is it required to create any LUN with hot spare RG? Because we can see the option with LUN to create as hot spare.

    Sorry for these basic questions

    Thanks in Advance

    DB:2.73:Creating Hotspare Rgs cs


    You will need to create a RAID group (of type Hot Spare) for each disk you have that is reserverd as a hot spare.

    You can have one hot spare available for multiple RGs. It is recommended to create Hot spares from the largest size disk of a given interface type (e.g. a system with 1 x 450Gb 15K drive and 30 x 300Gb 15K drives should use the 450GB drive as a hotspare). EMC recommended ratio of hotspares to data drives is 1:30 (for FC) and 1:15 (SATA), this is recommended you can have more or less as per your requirement.

    Here's what I did. I initiated the drives but when building a container, I only inseted 4 of the 5. Then I used the openmanage cd and set the server up using the server assistant. After the OS installs, use the Setup Server Assistant icon and set it up. Cery easy to do. Finally, drill down to I think virtual disk and execute the command to initiate the global hot spare. Thats about it.

    Why is my disk copying off to the hot spare if there are no indications of a drive failure? Should I have the disk replaced that its copying off from?

    DB:2.72:Cx4 Disk Copying Off To Hot Spare 1z


    If the drive reaches a certain level of errors, it will proactively copy the data to a new disk, and then fail the original drive. The proactive copy is much less overhead on the array/performance than a rebuild operation, as such proactive copy is preferred.

    Hi,

    Strange heading I know....

    I have new 2950 with a PERC 6/i, 6 - 500GB SAS drives and plan to install centos5 on the system.  I have created, via BIOS,  RAID 1 with two drives and RAID5 with 3 drives and a hot spare.

     

     

    My issue is that the RAID1 virutal disk-0 is ~465GB (2 500GB drives in one container) and this is correct and what I expect. 

     

    However the RAID5 virutal disk-1 with 3 - 500GB and 1 hot spare,  vd-1 is ~930GB in size.... I would think that it would also be ~465GB.  Same size as each individual disk.

     

    I thought that the RAID5 would put all of the disks in one container equal to the size of the individual disks. That way if one drive fails, I can replace it and the drive will be rebuilt with the data from the other drives.

     

    Any know why my RAID5 container is listed as the total size of ~930GB instead of ~465GB? 

     

     Thanks

    DB:2.71:What Are The Procedures To Go With Proactive Hot Spare !! f7



    We have one disk failed in our environment (cx3-80) ,we have received about 500 warnings stating soft media error and critical error stating initiate proactive hot spare ..however due to poor monitoring we missed upon it and the disk failed....and though we had 2 hotspares configured of the same type and larger size ..still the flare does not initiated automatic hotspare...my doubts are below.

    1) why the hotspare has not automatically intiated by flare ,when the disk failed.,please be imformed I have checked and the hotspare configuaratiom meet all the

    requirement of the hot spare algorithm ie: size ,type and location

    2) proactive hot spare can also be initaited after the disk failed (manually) , as in our case the hotspare not intiated automatically ?

    3) can proactive hotspare be performed during business hour and does not need maintainence window

    4) performing proactive hotspare will automatically change the host access to new location ( hot spare disk )and will be served ,and after the replacement the data will automatically copied from hot spare to new disk.

    I have already refered this Kb aticle on this :

    If the disk has failed, then you can replace it any time.The dead disk has no role in regeneration process. As far as I know, Symwin has Disk Replacement Wizard which EMC CE uses for the purpose.

    Precaution has to be taken if there are multiple Drive Faluires. In that case, replacent is done one by one.

    I don't understand the effect of the variables size on the number of used DSP48E slices ?

    Another question, the DSP48E slice has 18 and 25 bits forrespectively A and B inputs, so what happen if the size of my quantized variables is greater than ? Is it the reason behind the increasing of the number of used DSP48E slices ?

    Go to Solution.

    DB:2.68:Number Of Dsp48e Slices Used 1j


    It is possible to cascade DSP48E slices to handle larger word sizes. So this is the most likely

    explanation of the difference in usage. There is a user guide that describes the DSP48E and

    it gives examples of how many DSP48E slices it takes to handle various word sizes.

    My original idea was to have these different LUNS so that if one LUN experienced BAD I/O activity, the user experience would be ok on the other LUN's. I just read a post suggesting a 40 spindle LUN.

    So now I am thinking about these questions:

    Do I have anything to gain by having few LUNs with more spindles?If the number of users stays the same, than does it really matter?

    Yeah, that is sort of what I thought too. I tried to find a good balance between I/O saturation and# of datastores.

    The SAN I have is an HP p2000, and it doesn't have any peristent cache that I am aware of.

    Each controller a has a cache, but I am pretty sure that is internal to the controller and I can't place files there....

    From the Quick Specs:

    2GB transportable read/write cache (per controller).

    Machine ran fine for a couple of years. Came in today to find it rebooted and was stuck on the RAID screen finding only 1 of 3 VDs and foreign configuration. None of the drives or cables were moved. No amber lights on any drives.

    Went into PERC configuration and attempted to import foreign configuration. Import failed for all 3 VDs. Pulled power and reseated all 8 drives (did not change any positions) and import failed again.

    All 8 PDs are visible with 6 marked foreign and 2 marked online (VD1 - PD 01:02, 01:03). I did notice that the hot spare seems to be in use for VD0. In the Foreign View, the PDs for VD0 are listed as 01:00, 01:07, not the original config.Please see notes below.

    Would appreciate any advice. Does this have something to do with 01:07 being utilized by VD0 and that they are different types and size of drive? I thought I would be OK with the hot spare being larger... Is a retag my only option? Would appreciate detailed retag steps and how to handle the in-use hot spare with a retag. Data is backed up but I really would like to rescue this config. Thanks!

    No you can not. Sync rate depends to multiple factor. Backend utilization. WP utilitzation. You can only estimate it based on the size of the disk but you wont be able to find out the exact figure.

    Thanks,

    Saurabh

    Hi there,

    Now i must admit that i am a bit of a Solaris novice, but a few Google searches convinced me that i need to run a FORMAT/READ/ANALYZE for the disk, but was unsure as to which actual disk has the issue.

    The FORMAT command returns the following disks........

    I then ran 2 ANALYZEs .... 1 for c3t11d0 and 1 for c1t0d0 which both look like they could be possibles but they both came back clean.

    Can anyone confirm which disk i actually have a problem with please, and how serious it is .

    Should i be looking to swap it out ????

    TIA

    Thanks for the update Martin,

    I will print off your instructions and decide when we can fit the work in.

    I dont know what i have done to deserve this, but not only have i experienced this disk issue, i have also had a disk issue this weekend on a HP server, and to add insult to injury, i have trapped a nerve in my back between 2 discs this weekend !!!

    They say they come in 3's though i suppose............

    Thanks again...............i will keep you posted.

    DB:2.67:Hot Spare Count And Proactive Copy x8



    Article 7605 recommends 1 spare per 30 drive count. And the same recommendation can be found in VNX Applied Best Practices Guide.

    But I am surprised there is no mention of the Proactive Copy feature. In a small array with only 2 DAEs (30 disks) and a single hot spare Proactive Copy would never be invoked. As a reminder, the proactive copy rules discussed in article 184475 require 1 available hot spares.

    Proactive copy seems like a good feature to enable, but is there a reason this is not mentioned in the recommendations?

    DB:2.67:Hot Spare Count And Proactive Copy x8


    KB Article 7605 has been updated to include the information about the minimum number of disks needed if a user initiates a Proactive Copy.

    Thank you for pointing this out.

    DB:2.66:Will Hot-Spare Disk Provide Protection In First Five Disks? zd



    Hi All,

    I am curious about hot spare disk protection.

    Will Hot-Spare disk provide protection in first five disks?

    Dennis Dai

    DB:2.66:Will Hot-Spare Disk Provide Protection In First Five Disks? zd


    Hi,

    Yes, the hot spare is global on the array, therefore will protect all drives on the array since it has enough capacity to accomodate the bound space.

    Keep in mind you must follow the hot spare rules regarding the drive types.

    There is a document called "White Paper: EMC CLARiiON Global Hot Spares and Proactive Hot Sparing - Best Practices Planning" on the powerlink.

    DB:2.66:Metareplace Help. kj


    Hi All,

    I have a Solaris 8 box that I inherited. Looking at the metastat report it looks as if there is a hotspare in use on d0, but the device c1t9d0s6 state is ok. I'm thinking that a drive may have been replaced and the metareplace command was never run to release the hotspare, but I'm not sure.

    Could someone please take a look at the report below and let me know how to proceed, little nervous about hosing this machine :)

    Maybe something like : metareplace -e d6 c1t9d0s6

    Thanks,

    Joe

    It looks like the hot spare c1t11d0s6 automatically took over and the disk . After the original drive c1t9d0s6 has been replaced, make sure that the replacement disk has been partitioned to match the disk it is replacing before running the metareplace command.
    Then invoke the metareplace command you suggested to bring the mirror back to normal operating state.

    DB:2.66:Corrupted File? z9



    I was putting slice mockup file for engineers which contains slice names and XY.

    When I open the file, it changes shape and size of slices.

    Randomly PNG32 slices will turn into square or rectangular white blocks.

    Thumbnail shows the correct image and if I reopen many times, I'll eventually get the right file open.

    Also, if I work off of a wrong file and save, it contains all the wrong slices and changes the thumbnail.

    I tried to open in different computer, different FW and it behaves the same.

    Also I saved in different location, replaced with new slices, backup the slice with path, changed DPI... etc.

    Non of it worked.

    It seems like slices bordering with canvas are the ones causing problems.

    Anybody had similar experience?

    Is this just corrupted file?

    If so, is there any way to diagnose?

    Any input would be appreciated.

    Thanks in advance.

    DB:2.65:Error In Hot Spare Disk Ax150i fx


    Hi everyoneI receive an email error from my AX150i:"A disk drive has been powered down by the storage system because of a failure it detected (marked removed), someone physically removed it (marked empty), or the disk drive never powered up (marked empty). An amber light next to the faulty drive will appear if there is a virtual disk on the disk drive. See the AX-series troubleshooting documentation for replacement instructions"I dont know how can I do, in hot spare menu I get this message:"The Hot Spare created does not match the actual disk's capacity. This might be caused if the Hot Spare disk was swapped with another disk of a different capacity. Please destroy the Hot Spare and create a new one to reflect the actual capacity of the disk.The hot spare disk has been removed."I read in manual that hot spare disk will be create before create virtual disk, so I dont know if I can destroy Hot Spare disk and create a new one, I'm scared of virtual disk crash if i do this.Anybody can help me?Thanks a lot.

    DB:2.65:Error In Hot Spare Disk Ax150i fx


    The error message seems explanatory to me, the hot spare was created on a disk then that disk was physically changed to one of a different size. The configuration for a hot spare now does not match the size of the physical disk.

    Destroy the hotspare, configure a 'new' hot spare, then the array should rebuild onto it ready for you to replace the failed disk.

    DB:2.65:Hot Spare Across Active/Active Heads a3



    Getting back into NetApp after a 4 year hiatus and need a refresher on hot spares.

    Hardware is a FAS2020 dual head active/active setup, single shelf, 12 x 450GB FC disks, OnTAP 7.3.2

    If I do 1 aggregate, raid dp, will 1 hot spare disk be sufficient to fill in for ANY disk that would fail? I have something stuck in the back of my head about hotspares needing to be owned by a head, and I'm not quote sure how that factors in with this hardware

    DB:2.65:Hot Spare Across Active/Active Heads a3


    That is an interesting options Bakshana. Why would that not be considered best practice? Is it because of lack of actual hot spare on 1 of the aggregates, or because of general best practice being to balance disks as evenlly as possible across controllers?

    DB:2.65:Emc Global Hot Spare Configuration In Clarion Ax-4 cs



    Hi,

    We have EMC Clarion AX-4 DPE with 2 Disk Array Expansions. For the DPE, we have 12 disks, which are all bound to a RAID Group.

    Below is the Configuration.

    Disks 8,9,10,11 - RAID 1/0

    Disks 4,5,6,7 - RAID 1/0

    Disks 0,1,2,3 - RAID 5

    Right now, EMC is not agreeing for a service contract as there is no global hot spare configured. Is there any way to configure one of the disks as global hot spare without affecting the data on the disks.

    Your assistance is appreciated,

    Thanks and Regards

    Alex Antony A

    That option is dependent on whether or not he has sufficient space on other RAID Group to Perform LUN Migration!

    DB:2.64:Mirroring And Drive Rebuilding 1m


    Say you have an array of 1tb drives and you have a hot-spare configured. If one drive in the array fails and the hot-spare kicks in and starts rebuilding can you replace the failed drive before the hot-spare has finished rebuilding without causing issues to the array's volumes?

    Thanks

    DB:2.64:Mirroring And Drive Rebuilding 1m


    Sorry to hijack an old thread but my question relates to one of the posts

    I have a EQL PS4000X that had a disk stop working, it did fail over to one of the hot spares i had setup but when i removed and replaced the disk it didnt fail back as you describe that it should.

    I have not found a way be sides ejecting other disks that would get the disk back active again to see firstly if it is now ok or if it is indeed actually dead and requires replacement.

    are you able to advise that if there is a manual of bringing the disk back online?

    DB:2.64:Pv 650f Hot Spare And Rebuild xf


    I made an a RAID 5 array using disk 0-8 and made disk 9 as a hot spare. Bound the LUN up. Then I pulled disk 8, to see if the hot spare would get picked up. It did. Rebuild started. Then I pushed disk 8 back into, thinking that it would rebuild on disk 8 instead of spare, but no. Rebuild continued with the spare and disk 8's light stayed solid (non-blinking). Is this the normal way it rebuilds? It seems like it's rebuilding onto the spare, then when that's done, rebuild again on disk 8?

    DB:2.64:Pv 650f Hot Spare And Rebuild xf

    On the Clariion array, the hotspare will complete the rebuild, and then equalize to the replaced disk. This is to ensure data integrity.

    DB:2.64:T3+ Volume Slice Issue mf


    I have two new T3+ arrays setup as separate systems
    Both have the same issue. Both have the latest advised release of the T3+ firmware.

    I set them to be a Raid 1+0 mirror (4 drives mirrored
    to 4 drives) with striping across all "4" drives. The nineth drive is a hot spare.

    I then setup the new Volume Slicing and divided the large 250GB or so virtual disk into muliple 36 GB virtual subdrives. The last "subdrive" in the T3 falls short and ends up being around 24GB. I fdisked all the drives and broke them into standard slices for what I need.

    I rebooted my solaris 9 ue420 and it sees all the "drives". I can format all the 36GB drives. When I format the 24GB drive, I get back an error message about mismatching disk geometry and the format aborts. The format on any subdrive never takes more than a second
    because the T3 basically overrides the function, but usually I can do a worst case verify on the subdrives

    Obviously what the T3 controller is reporting back to
    the OS does not match what the drives geometry
    really is and things dont match right.

    I am trying to avoid the software overhead on my UE420 of Veritas or Online Disksuite volume managers for these arrays and want to have the
    sparc processor in the T3 handle all the mirroring and volume slicing of the 72GB drives in these arrays.

    Anyone seen this type of issue before with a volume slices T3 array?

    (this has also been cross posted on the Talk to the sysop forum. apologies in advance for the redundancy)

    DB:2.63:Perc 4/Di Issues m3


    I have PE2600 with a 5 disk RAID 5 layout of which one disk is a hot spare.

    if one drive fails, the spare kicks in correctly and builds which is fine. however when replacing the faulty drive, the new drive doesn't assign itself back into the array.

    Having worked with compaq servers I would expect the following, that when the new drive is inserted this should build back into the array and the original hot spare would then de-activate from the array and then assign itself back to hot spare.

    with the PE2600 i have had to go into the array configuration ctrl + m and set the new disk as the hot spare, leaving the original hot spare in as part of the 'live' array.

    i have updated the bios / firmware to the latest versions with the same results.

    comments / suggestions / help would be very much appreciated.

    DB:2.63:Perc 4/Di Issues m3

    This is working as designed. The Dell controllers do not handle the hot spare the same way that the HP/Compaq do.

    This server has been setup this way for over a little over 12 months but I'm not sure if the "logging" option was ever on in vfstab.

    If is was on, what would have caused it to be turned off and how do I turn it on again.

    DB:2.63:Ufs Logging Question 18

    Hi all,

    I'm having a problem at the moment with UFS logging. I mirrored my diske using Solstice Disk Suite GUI and everything appeared ok.

    This is the /etc/vfstab after the mirroring

    #device device mount FS fsck mount mount
    #to mount to fsck point type pass at boot options
    #
    #/dev/dsk/c1d0s2 /dev/rdsk/c1d0s2 /usr ufs 1 yes -

    As can be seen the "logging" option does not appear after the 4 UFS filesystems

    This server has been setup this way for over a little over 12 months but I'm not sure if the "logging" option was ever on in vfstab.

    If is was on, what would have caused it to be turned off and how do I turn it on again.

    Just as an aside:

    I configured another system lately and went through the same Disksuite Installation and this is the vfstab file

    #device device mount FS fsck mount mount
    #to mount to fsck point type pass at boot options
    #

    So tell me, is slice 4 being mirrored or not? Is the "fix" as easy as just changing vfstab to /dev/md/dsk/d40?

    So tell me, is slice 4 being mirrored or not? Is the "fix" as easy as just changing vfstab to /dev/md/dsk/d40?I suspect that action might cause you to fatally corrupt your filesystem.

    ....

    It is probable c1t0d0s4 is good, c1t1d0s4 is degraded.

    ....

    I would probably want to take a backup of what you have currently.

    .....

    I would probably want to be doing a metadetach to break off he bad mirror, then remount thange the vfstab to reference and mount d40, and metattach to resync the 'yffy' mirror d42 from the bad.

    Maybe an fsck in there might be good..

    ....

    IMHO Dont trust what I say ... make a plan and be very very safe and careful.

    DB:2.62:How Can I Group Volume More Than 30 Disk On 6540 9x


    When I create RAID-1 profile and set number of disk to variable (Max 30 disk).
    Then create pool and found avaliable size only 1 TB.

    I need group all 94 disk drive (exclude 2 hot spare) for RAID 1+0.

    How can I expand number of disk.

    DB:2.62:How Can I Group Volume More Than 30 Disk On 6540 9x

    The limit on a 6540 is 30 disks per volume group. Given your sizes, I'd guess you're using 73GB disks.

    The only thing I could suggest as creating multiple volume groups and using a volume manager on the host to build the multiple 1TB volumes into a suitably sized metavolume.

    Because you're using RAID1, you're not going to suffer any more RAID-overhead with multiple volume groups.

    For example if 4 disks are in the hot spare pool, how would you remove 2 of them to make use of them in a storage pool?

    DB:2.62:Slices In Fireworks 37


    I have a page in Fireworks where I have a placeholder to the
    left and a different size placeholder to the right of the page. I
    created slices over these. The slices are different sizes. After I
    export and place into Dreamweaver I delete the placeholder and
    place my text in. Because the slice on the left of the page is
    longer than the slice on the right of the page, I get white space
    in different areas of the page when viewed in explorer. I noticed
    that the white space is created when I extend my left side text
    beyond the slice of my right side. If I stay the same size as the
    right slice, it looks fine. Is there a way to avoid this? It's like
    the slices are connected but they aren't. Please help if you
    can.

    DB:2.62:Slices In Fireworks 37

    Fireworks makes a hard-coded table to represent your page
    layout. When you delete the placeholder images and replace them
    with text, there is no guarantee that the sizes of the cells will
    retain the sizes specified by Fireworks. Your table breaks.

    What you should do is make your graphics in Fireworks and
    your HTML in Dreamweaver. Fireworks is a graphics program, it is
    not a WYSIWYG HTML development environment. The code it produces is
    intended to be used for mockups and prototypes, not for real sites.
    Build your HTML from scratch in Dreamweaver and you won't have the
    problems you get trying to modify Fireworks' fragile HTML.

    DB:2.62:Metalun Fail After Drive Replacement k7



    Last week one drive failed failed from a LUN which is contained in a MetaLUN. The drive in question was a 73GB. While we didn't have a 73GB spare in stock, we replaced it with a 146GB drive.The replaced drive did rebuild and all looked fine. UNTILL we restarted our CX-600 yesterday.

    The MetaLUN doesn't come online, the displayed status says: shutdown. One of the MetaLUN compontents (1 out 4 LUNs) go owned. Apparently this is a problem in the flare version:

    CX200, CX400, CX600 LUNs may fail to assign (go

    unowned) after a drive replacement, a hot spare

    equalize where the hot spare is a different size than the

    drive it replaced, and then a trespass to the peer SP.

    (112437)

    Fixed in Revision: 02.07.010

    Solution: Correct defect in code that determines the

    rebuild checkpoint following drive replacement.

    What to do?

    Can i change the drive in question with a 73GB spare, without losing anything..?Does al start working again?

    Thanks for helping!

    DB:2.62:Metalun Fail After Drive Replacement k7


    The SR# is 45376354. The only thing the tech/engineer could tell me was "i have to investigate the problem and come back to you next day". Next day the same answer, while I presented him all the information I also posted in this discussion. This problem is also known by EMC, while it's described in a release note.

    Personally i think this is unacceptable, waiting 3 days to get possibly, not even sure, a solution to get the critical data back.

    At the end of day 2 i got a call from another worker from EMC that they couldn't find (after 2 long days!) a valid support contract. So after 2 days of pretended investigation, they coudn't help me anymore. Also if there was a valid support contract available, i guess you can't let your customer wait for 3 or more days to get business critical information back. That's why i started to reproduce the issue and tried to find a solution on my own. Thank god all worked out as expected!

    Personally i see this kind of problems as a factory defect which need to be supported, regardless if there's an valid support contract available. If i buy a car with one year of warranty and the computer of this car starts doing odd things like, accelerating while not requested, after the warranty is expired, because of some bad code, the code/computer is replaced without any additional costs. I think this scenario is the same as the one described in the beginning of this discussion, while this both could lead to very dangerous situations. You may expect a proper operation of this piece of hardware. Anyway, this is my opinion..

    That aside, the problem is solved by replacing the bigger disk by a disk of the original size. Caution, i think it's a risky operation, while the hotspare doesn't kick in for some reason. The device starts rebuilding on the new disk right away! Also, after inserting a disk of the original size the LUN will become accessible directly after the drive has been initialised.. I needs to be said that this problem only occurs when the CLARiiON is restarted. Replacing a 73GB disk by a 146GB without restarting, will function without any problems!

    Thanks everyone for helping on this one..

    DB:2.62:Ns120 - Added Some New Drives - Need Advice On Sizing a7



    Hello everyone,

    this is the situation: a happy running ns120 with Unisphere, the system is basically servicing a Vmware infrastructur through iScsi using VMFS, no particular requirements. I have added some new drives and the drives are recognized from the system and marked as "unused".

    Pretty much we are talking about 6 SATA (total capacity about 3.5 TB in RAID5) drives and 6 SAS (Total Capacity about 2.5 TB in RAID5) drives.

    I was thinking of:

    - create 1 Storage pool in RAID 5 (all 6 SATA drives) with no hot spare (there is already an hot spare in the system)

    - create 1 Storage pool in RAID 5 (all 6 SAS drives) with no hot spare (there is already an hot spare in the system).

    - create 3x1TB LUNS out of the SATA pool and leave 500GB in the pool unassigned to expand the single LUNs if needed in the future.

    - create 2x1TB LUNS out of the SAS pool and leave 500GB in the pool unassigned to expand the single LUNs if needed in the future.

    My question sare:

    - is my sizing correct (storage pools and LUNs size considering that will serve VMware thorugh iSCSI).

    - do the hot spares will cover the ENTIRE system or just the pool previosly configured. I mean, the hot spares configured in another storage pool will kick in if a fail drive occurs in this storage pool or not.

    - will these operations have any impact on the live enviroment or not.

    thanks

    DB:2.62:Ns120 - Added Some New Drives - Need Advice On Sizing a7


    are you using iSCSI through the datamovers ? You can present new LUNs and configure them as datastores online.

    You are correct, hot spares are global.

    DB:2.61:Hot Spares - Why Is The Mechanism Varies In Different Arrays mf



    hi,

    in most of our EMC arrays if we have a faulty disk in a RG , hot spare kicks in and rebulds the data , once that is done , that data is copied into the new disk which replaces the faulty one, why is it in some arrays like HP or netapp , the hot spare becomes the member of the raid group and the new replaced disk is configured as hot spare.

    why does EMC or other storage vendors do data movement/rebuilding twice , it just brings more load on the array isn't it?

    DB:2.61:Hot Spares - Why Is The Mechanism Varies In Different Arrays mf


    The nice thing there with VNX2 is drive mobility

    After the rebuild you can move your rebuilt disk to the physical slot of the failed one

    As long as you do that within 5 minutes McX will cope without failing the disk

    DB:2.61:Fas3210c (8.1.1) And Ds4243 - Raid Group Size And Hot Spares? 8p



    Hi

    We have just connected an additional shelf of 600GB 15kSAS DS4243.

    Currently my controller which I'm adding the shelf to has 2 x RG (16 Disks) - RG0 has 16 disk and RG1 has 6 disks. That leaves 2 spare

    What is the best option about adding this new shelf? Do I leave the RG at 16 disks? If I do to give best performance and balance I have to use 26 disks which leaves only 1 spare.

    Do I increase the RG size to 23 and use 24 disks so the RG are balanced?

    Thanks in advanced!

    RAID groups are very unbalanced now (16+6), but should be fine after adding more disks (16+16+14).

    Is it possible to order the slices in a Reporting Services 2008 pie chart, so that they are in order of magnitude (size) from largest to smallest?

    Hi Chris,
    To this question, you could add a sorting datafiled to the pie chart, steps are below:

    Right-click the category datafield at the bottom the chart, and then select Category Group Properties.
    Switch to sorting tab, then click Add button to add a sorting datafield. Click Fx button, then type in the expression =Sum(Fields!YourDatafield.value) here YourDatafield is the datafieldon top the chart.

    Then the slices will be displayed in order of magnitude (size) from largest to smallest, just like you mentioned.
    Best regards,

    DB:2.61:Disksuite Problem / Db On Errored Disk kx


    I recently had a problem on one of my mirrors on my system. The only thing on the drive that has an error is 2 slices, one with data (/export/home) and one slice for the metadb data. I don't think the drive is actually bad, it just appears that it may have needed a fsck to fix things. I was able to fsck the data partition that I have on slice 0 with no problems, but then I noticed if I fsck slice 7 the metadb slice that I get the following: (below) I don't recall using alternate super-blocks for fsck and didn't want to chance making things worse. Is there an easy way to remove the metadb from the disk and then I suppose I would also have to unmirror the drive and re-establish the mirror?

    Any suggestions?

    DB:2.61:Hot Spares 15k 10k Rpm 78



    CX3-10, originally single tray of 300 GB 10K RPM FC disks. Adding a second DAE with 300 GB 15K RPM FC disks (obviously a single bus so both will be forced to 2Gbps, understood). The original DAE has an existing (10K) hot spare provisioned.

    When provisioning a new 15K hot spare, since both 10K 15K disks are the same size and both are FC, in the event of disk failure, can it differentiate RPM class and know to use only the 15K to rebuild an RG of 15K disks (and ideally only the 10K for the 10K RG, since I don't want to waste a 15K disk on this)? If it can't tell the difference, does that mean I need to go with only 15K hot spares to guarantee only 15K disks will be used with other 15K RGs? Or is there some other way to isolate?

    Thanks! dk

    DB:2.61:Hot Spares 15k 10k Rpm 78


    dk,

    The hot spare is only temporary. In your example, after you replace the failed 10k disk with the replacement disk, that replaced disk will be rebuilt and then the hot spare will go back to being available as a hot spare.
