Haven’t done it with VCS (we do RAC
on Linux which uses Oracle Clusterware).
As noted below the DB seen on each node is
actually the same DB so you only need to back it up once.
I’d recommend setting up RMAN to
backup via RAC’s virtual IP rather than either node’s physical
IP. Although it is one DB there is a separate instance on each node and a
virtual IP associated with each of those. On failure of a node the virtual IP
for that node fails over to one of the other running nodes. If you’re
backups rely on the virtual IP you won’t have to do any adjustment for a
failure of a physical node.

configure nodes of VCS Oracle Rac cluster asmediaservers
You back up a database, not a cluster, and
the one RAC database is on two servers. You only need to have one
media server and you can run the backups through that one server.
If you intend to have more than one media
server, you'd have to figure a way to divide the database tables of the single
instance across two servers and the admin of that would probably be too much
hassle. If you've got one instance on two server, just ignore the other
server for backup purposes.
My $.02, at least.

Subject: [Veritas-bu] configure
nodes of VCS Oracle Rac cluster as mediaservers
Hi, I am configuring a 2 node VCS cluster for backup and i would like
to know the recommendations for doing this. Both nodes will have access to a
virtual tape library which is san connected. The cluster is running Oracle RAC.
I have installed the media server software on each node of the cluster
and used the physical node name during the install. I want to back up each node
directly to the virtual tape library.
DO i need to run the cluster_config script? I do not necessarily want
Veritas to manage media server failover between the nodes as this is an
active/active cluster.
Should i configure each node of the cluster as though it were an independent
SAN media server?
