Microsoft SQL Clustering and PPME
Recently had a customer ask questions around PPME & MSSQL for a multi-node Microsoft Clustered Migration.
I thought I read awhile back in PPME that the passive node (nodes in this case)are not required to be down, as PPME is now is cluster aware.
Seeing as I cannot find the documentation that states this I am looking for the following and hoping you guys can help.
1. Is this correct?
2. If yes on 1 can you please pass along the document
3. Is a reboot still required to the window clustered hosts? or just the commit commands?
Please advise and Thank You!!

This is correct, however, the new way of using PPME with all nodes remaining up, this is for windows 2008 servers and higher.
if you still have windows 2003 server than the other nodes must remain down while only 1 node the active node running the migration remains up,the way things used to be.
**with PP 5.7 SP1 this new feature for using PPME does exist that all nodes may remain up during the migration but must have server 2008 or higher.
no reboot required. document is attached pages 40

fyi with 2003 server the -cluster option is not used, but is now used with PP 5.7 SP1 with 2008 server and higher.

I believe it was PowerPath 5.7 SP1 that introduced that functionality, look at the release notes for that version.
