Re: [Veritas-bu] Standalone to Custered migration

Earlier this year, I replaced the master
server cluster at a previous employer. We went with the same vendor,
namely Sun, but while the old servers were still in operation I built the
new servers in a cluster. According to Veritas support, even the
node names of the nodes in the new cluster had to remain the same, so now
that I think of it, going from non-clustered to clustered in this way probably
wouldn't work. The EMM DB _does_ contian information about the NetBackup
cluster and which of the nodes is active.
There's probably some magic that can
be done on the EMM DB with nbemmcmd to update it with cluster information,
but Symantec is probably the only one who knows the incantation.

doing a bprecover sounds like it might work. Just make sure you make the
cluster name the same as the name of the original standalone. You definitely
want to read the HA guide. What clustering software are you using?
You are correct:
>From the “Veritas NetBackup™ High Availability Administrator’s Guide”
(NetBackup_Administorator_HighAvalability.pdf) document:
Page 14: “NetBackup does not support the conversion of an existing non-failover
NetBackup server to a failover NetBackup server. Contact Symantec Enterprise
Technical Support.”
In other words, this requires consulting services.
I guess that's what you get for not reading the first couple of chapters
because you think they are just a bunch of fluff.
We've tried doing the recovery after configuring it in the cluster. The
problem at that point is that NetBackup is not aware that it's in a cluster,
which causes a big problem with the device configurations.
We are using the latest version of VCS, so it's definitely supported, just
apparently not with using our old EMM database. Any ideas on how
to remedy this situation, or when it will be supported? I really
don't want to have to re-inventory or loose 7 years worth of old tapes.
Maybe we can get one of our DBA's to crack open the Sybase Database and
find a solution to our problem?
