Pinned topic V7000 migrate volume (N6040 DataOnTap OS Volume) to other Pool

‏2012-02-24T04:51:52Z |
Hello!

Currently, in V7000 we have a Pool (PoolA) with a Volume (PoolAVol1) assigned to N6040 for DataOnTap(8.0) system.

Now, we have a new Pool (PoolB) in V7000, using other disks, could we use “Migrate to Another Pool” real time migrate PoolAVol1 to PoolB with no down time? Is it a correct way to relocate DataOnTap system volume?

I tested, Migrate volume with Data is fine, but I am not sure if volume with OS.

thank you very much!

    I think you means using nSeries gateway to access V7000 volume. If this is the situation, it is not supported officially. But it maybe still work as you experienced.

    Hello~
    Yes we are using nSeries gateway connect V7000 and it was recommended by local IBM last year. We now want to move all DataOnTap OS+Data volumes from PoolA to PoolB. Tested migrated data volume was success. But we are not sure the OS volume and we have no way to test. That's why I want to get support from IBM but seem no people from my local support can answer till now. Maybe it is really not support so I need to find another way. thanks!

    1) Validate the current root volume (usually vol0) and the new root volume:
    vol status

    2) Ensure that the ndmpd daemon is turned on using the ndmpd on command on the filer.

    3) Copy the entire /etc directory from the current root volume to the new root volume:
    ndmpcopy /etc /vol/new_rootvol/etc

    4) Flag the new root volume as the root volume:
    vol options new_rootvol root

    5) If desired, rename the old and new root volume. The following command renames the volume :
    vol rename

    6) Verify that the shares and exports are updated accordingly, by running the following commands:
    cifs shares
    exportfs
    Reboot the filer
    Verify the new root volume settings:
    vol status

    Hi,

    Not really sure if I have catch your question correctly. I understand you have a StoragePool A and B; then you have a vdisk created on StoragePool A and now you want to move to StoragePool B ?

    The pre-requisite to migrate vdisk around StoragePool is the size of extent, they must match (exactly the same).

    I'd recommend to run in low I/O activity to avoid major issue; the migration supposed to be transparent.

    Thanks !
