HP 3Par Replacing a Failed Disk

Replacing a failed disk in a 3PAR is pretty simple you just need to follow a few steps to make sure you do it safely. If you are new to 3PAR or would like to learn more a good place to start is our 3PAR beginners guide

Let’s get started with the disk replacement procedure:

1 Check to see if you have any failed or degraded disks in the system. Take a note of the disk ID and cage position. In this case disk ID =26, cage position = 2:8:0

3PARSAN01 cli% showpd -failed -degraded

                           -Size(MB)-- ----Ports----

Id CagePos Type RPM State   Total Free A     B     Cap(GB)

46 2:8:0? FC   10 failed 417792   0 ----- -----     450

------------------------------------------------------------

 1 total                  417792   0

2 Check if the disk sevicemag command is running on the drive. The servicemag command is used to inform the system to evacuate all the chunklets from a drive so that it is ready for service. Below we can see the servicemag has succeeded on the drive we identified in step 1.

3PARSAN01 cli% servicemag status

Cage 2, magazine 8:

The magazine was successfully brought offline by a servicemag start command.

The command completed Thu Jul 10 20:07:03 2014.

servicemag start -pdid 46 – Succeeded

3 Next we double check there is no data left on the drive. You can do this by running showpd –space driveID as below. You need to check that all columns other than size and failed are zero

3PARSAN01 cli% showpd –space 46

 

Id CagePos Type -State-   Size Volume Spare Free Unavail Failed

46 2:8:0? FC   failed 417792     0                 0     0          0         417792

---------------------------------------------------------------

1 total                        417792     0            0   0          0        417792

 

4 Next to replace the physical disk. Make sure you are happy with the above steps. Then pop that bad boy out, you will have a note of the location of the failed drive from step 1.

 

5 Once the disk is in you can monitor the progress of the rebuild by running servicemag status, which will give you an ETA for completion.

3PARSAN01 cli% servicemag status

Cage 2, magazine 8:

The magazine is being brought online due to a servicemag resume.

The last status update was at Thu Jun 26 12:09:19 2014.

Chunklets relocated: 73 in 50 minutes and 34 seconds

Chunklets remaining: 400

Chunklets marked for moving: 400

Estimated time for relocation completion based on 41 seconds per chunklet is: 4hours, 57 minutes and 39 seconds

servicemag resume 2 8 -- is in Progress

6 Once this is complete you can check that your disks are showing in a normal state with showpd -state

3PARSAN01 cli% showpd -state

Id CagePos Type -State- --------------------Detailed_State---------------------

43 2:5:0   FC   normal normal

44 2:6:0   FC   normal normal

  1. I believe servicemag resume cageposition is not necessary with 3.1.2 and newer. System will automatically detect new PD and start rebuilding.

  2. Hi Richard,

    Thanks for your article on replacing HDDs.
    I have a requirement to replace 4 HDDs on a 8 cage 7400 3par box.
    Is it possible do so at the same time?

    1. Not sure why you would be replacing 4 disks at the same time. If they are already failed I see no harm in replacing them with a brief pause inbetween. If you are removing disks for any other reason I would do one at a time.

  3. DIsk 3 failed on our 7200 node. The disk ID was 3 and when the “relocation” started on the new replaced drive the new disk was assigned disk ID of 48. Is there a way to change IDs?

    1. Hi you are quite right the ID will change after a disk swap. I have never seen a way to change back, but will publish your comment here to see if anyone else has come across this. Thanks for reading!

  4. Hi,

    Have a V800, with a failed disk within a 4disk cage. Its state is failed, and the disk is empty when showing showpd -space pdid as you describe. When I run servicemag status Im not seeing any servicemag operations like you have shown, it just says “no servicemag operations running”. Any thoughts? Do I need to perform something active before replacing the disk, ie. pulling out the cage?

    1. Hi. The disks on the V800 are held in disk magazines of 4 disks as you describe. The servicemag command will work at the magazine level and log or relocate the data from all 4 disks in the magazine you wish to remove. When the servicemag command has completed you can remove the magazine.

      1. Thanks a bunch, it worked and the drive has been replaced now 🙂

        I have another question:

        I have 2 disks in degraded state, 1 in a 7400 system and 1 in a v800 system. But it remains in degraded state and does not change to failed as I would expect it to do after some time?

        Is there a way to force it into failed mode or will I be able to run the servicemag start on these disks even though they are only in degraded state?

        1. It could remain in a degraded state if it had failed chunklets on it, you can check for this using showpd -c. The disk will only be marked failed automatically if it has 6 failed chunklets on it. Like you say you can force an evacuation by using servicemag start if you like. The only other thing I can think of is to check the firmware versions on those degraded disks look correct showpd -i. Good luck!

      2. hi
        in this case we run this command servicemag start -log -pdid 137
        and all the 4 disk datanil ( 3 disks are degraded state , 1 is faile)

        we didnt replace the disk untill 24 hours

        is this leads any impact

  5. Hello Richard,
    I’ve got 3Par InServ e200 system, and after replacing bunch of failed disks, I still have this error:

    Is there command to clean all the settings and make system like new. At this point I don’t are about any data.
    Thanks in advance
    Bohdan

    1. In this scenario : I would have first checked : showpd -p -cg 0 -mg 12, then for another drive and if there is more than 1 drives on particular slot, would have checked servicemag status, if it reflects succeeded, then we can go ahead and run dismisspd 1. We need to repeat this for all the drives reflecting above. To clean the system, the steps given by 3pardude is perfect.

  6. Hi
    I am using a HPE 3PAR StoreServ 7200 with 16 disk and 8 empty hdd bays. So I am going to add 4 new disk. I inserted new disks and did every single step right, but somehow it says “degraded” in status for a while and then “Failed”. What can I do?
    Thanks a lot, and sorry for bad english.

      1. yes, my 3PAR OS Version Was 3.2.1 mu2 and the hard disks was not listed in that version of OS, So i found out that i had to update OS at least to 3.2.1 mu21. i Updated that to 3.2.2 mu2 and that worked perfectly.

  7. I have a replaced a disk on Hp 3par 7400, the disk went online and rebuild completed. But the old disk (degraded) is still showing in the system. I’ve tried dismisspd without any luck. Any suggestions ?

  8. At step 3, you may use “showpd -c 46” to check the detailed chunklet information, other than “showpd -space 46”.

    1. You could run the Out Of Box setup again, but this would remove your previous config and volumes. But of course this would not be the same as a secure wipe ie the data could still be recovered by experts

  9. Hi Richard, I have a 7200 with a degraded drive, for which servicemag failed:

    The output of the servicemag start was:
    servicemag start -log -pdid 11
    … servicing disks in mag: 0 11
    … normal disks:
    … not normal disks: WWN [5000CCA016117623] Id [11] diskpos [0]
    … not vacant disks: WWN [5000CCA016117623] Id [11] diskpos [0]
    disk Id(s) [11] must be vacant before servicemag start -log is issued.
    Issue the command “movepd -devtype 11” to begin or continue disk vacate.
    Chunklet movement may be monitored using the “showpd -c 11” command
    servicemag start -log -pdid 11 — Failed

    movepd does not help on vacating the drive, Here is showpd -c output:

    I understand that I cannot proceed with disk replacement unless OK and Fail are 0. Any tips on what to do now? OS is 3.1.3 MU1

    1. Hi Mario

      You are quite right, do not proceed until all chunklets have been moved from the disk you are trying to remove. I think the issue is that you are using the -log option this is meant for 10K systems where a magazine contains multiple disks. You need to run servicemag start without the -log option, the format is servicemag start -pdid . So in your case servicemag start -pdid 11

      Hope that helps

      Richard

  10. Hi Richard

    I have failed drive in a 7400 and I want to remove it and not replace it. The system automatically ran servicemag when the drive failed so not sure how I go about dismissing that pd?

    Thanks
    Nathan

    1. Hi Nathan

      You would need to follow the process below, you can skip 1 as you have already moved the data

      1. Empty the drive (assuming plenty more drives above the cpg set-size * rowsize) behind the same node) -> movepdtospare -vacate -nowait

      2. Remove spares -> removespare :a

      3. Dismiss pd from config -> dismisspd

      4. Offloop drive -> controlmag offloop : (drive maintenance led will now be lit)

      5. Physically remove drive

  11. Replace a failed hard disk on our 3PAR V400.

    Initiated the command “servicemag start -pdid 15 and the command was successful.

    Next we replaced the new disk.

    Then we inititated the command “servicemag resume 0 9” very soon (We cant sure whether the plug led has been off)but this command failed and we got the following error:

    V400 cli% servicemag status -d

    thank you

  12. hello dears, thanks for your post
    can i replace a failed disk with disk wich get big capacity than the failed and other disk of the magazine

    1. Yes you can use different size disks in a CPG. Personally I wouldn’t recommend it as the smaller disks will get full quicker than the larger ones and you will end up with an uneven load.

  13. Is it possible to low-level reformat a disk with a different block/sector size? I came across an older 3PAR being scrapped that was full of ST3600057FC 600GB 15K FC drives, the same model number as the kind we use in our 10000 series. Anyway, I just tried using one as a replacement for a failed disk… it was recognized properly and updated the disk’s firmware, but showing Invalid Sector Size in management console. Checking the block size using showpd, I see its formatted with 512b and my 10000 is expected 520.

    1. Hi David

      This is not something I have tried. But logically what you suggest make sense, give it a go and let us know how you get on.

  14. Hi Richard, Great guide! I recently replaced a failed drive in my 7200 and now my removed drive shows a ? mark by it. When I do a showpd -space PID it shows the following:

    Id CagePos Type -State– Size Volume Spare Free Unavail Failed

    1 total 838656 0 0 838656 0 0

    The new disk shows:

    1 total 1142784 608256 35840 498688 0 0

    is it safe to dissmiss the old drive ID 6?

    When I run a showpd -c 6 it shows:
    Id CagePos Type State Total OK Fail Free Uninit Unavail Fail OK Fail Free Uninit Fail
    6 0:6:0? FC degraded 819 0 0 225 594 0 0 0 0 0 0 0

    1. Hi yes from these screenshots looks like 4 is the new working disk and disk 6 is the old one that has not cleared its self from the system. If disk 5 shows as 0 space used which it looks like here I would dismiss it like you said

  15. Just want to recheck if I am correct!

    In the description its written 26 with below line!

    In this case disk ID =26, cage position = 2:8:0

    However in the output id is 46.

    1. The disk ID is just an auto generator number, I would focus on the cage position to make sure you are looking at the correct disk

  16. Hello

    I have some problem with hp 3par 7200 with 900GB FC HDD.
    one of the HDDs is fail about 1 month ago , the pdid of my hdd is 0 19 , i replace it withe resvicemag procedure and everything is ok.
    after 1 day my new hdd is normal and the failed disk is gone but next day new disk is fail , i replace the fail disk again and after 1 day everything is ok.
    after 1 month hdd in 0 19 fail again and i replace it but after 2 day the new hdd has fail again.

    may the os version is my problem?

    please help me about this problem.

    thank you

  17. Hi Richard. Thanks for your post!
    I had a one fail disk (900GB FC HDD) in hp 3par 10000.Then i reaplced failed disk on new same disk and other disks in that magazine became degraded. Why has so occurred?

    1. This could be due to the increased pressure on the disks during a rebuild led to the failure or that servicemag command was not correctly issued

  18. I want to format drives from a decomm array and use on another array. All volumes and CPG’s removed. Is controlpd format wwn only available on certain Inform versions? I did not see “controlpd format” as a option?

  19. Hello Richard
    I just made the firmware upgrade of an HPE 3Par 7200 which has version 3.2.1.

  20. hi.
    I have a 3par 7400 and one of my 3TB hard drives is failed.
    but now I don’t have any 3TB hard drives for replacing.
    Is it possible to replace a 3TB hard drive with a 4TB HDD?
    best regards.

    1. It is in theory possible to use a larger disk. But I would always try and keep things uniform, or you will have some disks filling up quicker than others
