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!

Re: V7000 migrate volume (N6040 DataOnTap OS Volume) to other Pool2012-02-29T03:59:58Z in response to ERICCCCCI 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.

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!

Re: V7000 migrate volume (N6040 DataOnTap OS Volume) to other Pool2012-02-29T15:04:31Z in response to ERICCCCC1) Validate the current root volume (usually vol0) and the new root volume:
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 :
6) Verify that the shares and exports are updated accordingly, by running the following commands:
Reboot the filer
Verify the new root volume settings:

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.
