The parameter Servername in the dsm.sys file specifies which options to use.
You can specify this parameter in the dsm.opt file.  I create two
directories with separate dsm.opt files and run the backups from separate
directories.  The key is for this parameter in the dsm.opt file to point to
which parameters you want.

A better way might be to create a third nodename that backups up the data on
the whichever server is primary.  Then when they fail over or whatever, it
doesn't have to be backed up again.  I am not sure if this is a situation
with Veritas though.

        Subject:        Backing up Shared Disks

        My TSM server is AIX 4.3 and TSM 4.1.3.
        My TSM client is Solaris 2.8 and TSM 3.7.1.2

        I have a Veritas Cluster that has a shared disk  to two servers. I
want TSM
        to back up the disk  wherever it is attached via the Virtual IP
Address. I
        talked to TSM support and they said this wasn't supported but I
could try
        having two stanzas in my dsm.sys file. The first would be for the
core
        server and exclude the shared disks. The second stanza would be the
virtual
        IP and would exclude the core system and backup the shared disk .
Naturally
        they would have two different include/exclude files. I tried setting
this
        up but when I run a backup it acts like it doesn't see the second
stanza.
        Does anyone have this running? Any help would be greatly
appreciated. Here
        is my dsm.sys file:
