Hi all, hoping someone has some experience with backing up a Windows SQL
cluster. I am having the below issues:
Netbackup 6.5.2, AIX master + media + Windows media.
2-node Windows SQL cluster = 2 physical servers, 2 virtual servers, 2
SQL instances.
Typically we have 1 virtual server + instance on each physical server
and this runs fine.
Each physical server has a dedicated backup NIC on 1GB LAN, and each has
a static IP assigned.
This works for backup fine, until a failover of the cluster happens
without a failback.
So we created virtual backup nics, that are tied to the real backup
nics. We did this via Windows cluster administrator.
Now when a cluster failover happens, the virtual backup IP's follow to
the active node - good.
However, if we set (in the hosts file) that the backup client is
assigned the virtual NIC, when the backup starts the master server can
talk to the client via the virtual backup IP, but the client responds to
the master server via the real backup IP. Netbackup promptly fails the
job, because of this discrepancy as seen in dbclient log.
If I update the hosts file to include the real backup IP of the host,
then the job runs fine. This of course would mean that everytime the
cluster failed, I would have to update the hosts file which would be
unacceptible.
How are others doing this?
thanks
