Power Path Migration Enabler question

Jump to solution

Hi,

I am migrating a large lun 1.7TB using PPME off of my cx3 to a vnx. We have lots of luns on that server which are that size and so because the data is frozen(no more writes), I figured rather than take a whole weekend of down time, I can migrate lun by lun at my leisure using PPME. My two questions are: do I have to offiline the lun I want to migrate(only reads are happening), and can I migrate a metalun? I checked the white paper and did not see a restriction listed about metaluns however, I wanted to get some feedback. Many thanks in advance! Admingirl

PPME is designed to migrate active/online volumes between disparate storage. PPME actually doesn’t care whether the LUN is thin, thick, meta, etc since it’s moving data from the host’s perspective.

No, thankfully it's a stand alone server.

If you hadn't noticed already, the latest release of PP 5.7 now supports clusters...

From the release notes for PP 5.7 SP1

"Support for migrations in an MSCS cluster environment without the need to either
shutdown any nodes in the cluster or disable any failover groups to perform a cluster

migration."

that is great news for folks with clusters, many felt nervous running with only one node online during PPME session and still having to take the resource offline to commit the session. Thank you Richard.
