As I understand this, you are not currently backing up any of the cluster
drives now with the regular BA client?

The usual way to do this is to create a "virtual" TSM client node.
Most of my customers register the backup clients for the local filesystems
as the node/hostname,
and register the "virtual" TSm client name as the cluster name to back up
cluster drives.

You install a second scheduler service that runs as the "virtual" TSM client
to back up the cluster drive(s).  (It has it's own dsm.opt file, and it's
own scheduler log - they should live on a cluster drive.)

That scheduler service has to be made cluster resource, and you typically
install that 2nd service on all the cluster nodes so that the backups of the
cluster drive(s) can continue, even if the primary owner noder goes down.
That 2nd service will typically be running on 1 node, and shut down on the
others.  The Windows clustering software is repsonsible for starting the
service on the other node, if the 1st node dies.

If you've never messed with the Windows cluster manager, have one of the
Winders admins give you a tour.

I'm hesitate to go any further because I'm a little confused by the
statement "we have different cluster drives active on different nodes".
You have to think a bit about what you are trying to accomplish, and what
needs to fail over.
If you never intend to run backups in a failover situation, you only have to
install the scheduler service for the cluster drive on one node.
(OTOH, I had one customer with 4 nodes active-active-active-passive with
different Exchange stores active on each node, and it resulted in 5
scheduler services being installed on each node.)

Anyway, look in the TSM for Windows client manual, there is an appendix that
explains exactly how to set up a TSM backup for a cluster drive.  If you
only have the 1 cluster drive you care about, it won't be difficult.

BTW:  are you aware that TSm 5.2, it's been out of support for a long time?
suggest you get upgraded soon.
