Need to migrate data from an HP MSA 1000 controller.

G'day,
I have about 2 TB of data which I need to migrate from an older MSA 1000 onto a CX4. I would like to use the
powermig utility as we have used it successfully in the past to migrate from older IBM ESS and Hitachi storage. The
MSA is nowhere to be found on the hardware support list.

Unfortunately, I don't have a spare MSA 1000 in my test lab and this system is in 24/7 production.

Has anyone successfully connected a server to an MSA using PowerPath, and migrated data using the "powermig techtype
-hostcopy" function to migrate data.

Thanks in advance

Hi there ..like the nickname :)

i checked E-Lab navigator and did not see Powerpath supporting MSA-1000, but i did see that SanCopy is supported between MSA-1000 and CX4. If you can get SanCopy license on CX4 you can pull data from MSA-1000. It's not an online migration as it would be with powermig but something to consider.

Are you be able to provision one LUN from the MSA to a test host, install PowerPath and connect to the CX4? Might be worth a shot.

We can try this however this is a closed environment and any changes would require 3 weeks of Request for Change approvals and then actual implementation.
May wind up going that route, but would have liked to know there is a case out there where someone actually connected to the device with PowerPath, even if it is only a single path to the storage. The RFC would require some kind of documentation saying that this has been tested elsewhere, otherwise the request will undoubtedly be denied and returned.

I'm not sure how to get you that information, unless someone sees this thread and replies..

SanCopy may be an option ...
Worst case is downtime as we Robocopy or securecopy the last data over to the new lun. Means reducing the paths from 4 to 1 on the MSA and installing powerpath for the CX ...

I'm not crazy about running HP's securePath and PowerPath on the same box, so I'd have to evict one of the cluster nodes, uninstall SecurePath, install powerpath, then reduce the paths to the MSA to 1 and add the path to the CX. then rejoin the cluster and try the failover before running the migration... but if I don't see the drive from the powermt display then I don't have a shot.

I would have liked to have zero downtime ... something that was alluded to at a businness conitnuity meeting by our superiors. Gotta love it, they promise, we deliver ...

There is an HP EVA 6100 in the room so I may see if HP has any migration tools that I can use to leverage that unit temporarily and then use the powermig to move it from the EVA to the CX ... although more work than I would like.
