Ok, so our main Problem:
Volume exported to SQL1 and SQL2 (same volume)
Copy exported to SQL1 and SQL2
in MPIO i see 4 Active and 4 Standby paths. Thats good i think.
On SQL1 the disk is active, on SQL2 it Shows reserved.
When we perform a Cluster Switch from SQL1 Server to SQL2 server, you should see the disks go offline on SQL1 and go online on SQL2 within a few seconds.
Sometimes, it really runs into a timeout after 15 MINUTES..only the disk Change!! And i don´t have a clue where to look anymore. HPE says, everything is finde on their end/system, so not very helpful
It worked a few months ago, but of course no one knows of any changes made. The amount of disks (at least 30 exported) could be a matter?
Ah can't help much with the Windows cluster side of things alas.
Assume both servers see the same set of active/standby paths and both servers have the same bandwidth to both arrays (i.e. cross site links aren't wet string)?
Do you have other clusters that still work or are they all broken?
In theory cluster switch should have no effect on array volume access, the exact same paths should be used by either server and you should be able to remove the 'copy' paths and the rcopy setup with no effect on cluster access and switching. Certainly that's how we've seen it in the past with an old Win 2008 cluster.
If both servers can access a LUN from both arrays all should be good, if that's all working then something like a windows hotfix missing maybe.
