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
