VCS v5.1 (Windows)
Using VCS for NBU cluster..... We have mirrored catalog SAN disk at 2 sites in campus cluster.
For testing, SAN mirroring link was cut first, then 10 minutes later the IP network cut between the 2 sites. The failover started after the IP network was cut, but failed because the 2nd node 'failed to import cluster dynamic disk group' (SFW logs).
I have heard this may have occurred because the active nodes disk had the most up-to-date catalog information, and because the mirroring was cut the secondary nodes catalog disk was 'out of date' so not brought up in case of data loss. Basically we ended up with one node being offline, and the other one faulted.
I hope that made sense? Has anyone heard of this happening before?
Is there a way in SFH to force an 'out of date' catalog disk online after a failover has faulted?
Any help would appreciated.
