Hello all!
Just one interesting question about VCS GCO. I was told that VxVM mirror
is not supported if using with Global Cluster Option. Only replicated
volumes can be used ...
Is it true? It seems strange to me... Why not? I think it is quite
possible to failover mirrored VxVM volume
To mirror volumes you must be dealing with a relatively small distance,
such as less than 80K. For these distances, why not use a single cluster
called a stretch or campus cluster? In SF 5.0 there is the concept
of site awareness so that VM is aware of the two sites and if a volume
at the remote
We made a decision to not support VxVM mirror in a GCO environment
because it breaks our ability to use SCSI-III based fencing. While you
could make the mirror work, it is not a Symantec supported
configuration. For dual cluster configs we would require some form of
replication.
