David,
The dsmcad has an option for the location of the dsm.opt file - see below:


client acceptor daemon:
dsmcad -optfile=/usr/tivoli/tsm/client/ba/bin/myopts.opt

Subject: TSM client backing up to two TSM servers

I'm trying (for political reasons) to back up a linux TSM client (v5.4) to two 
different servers (v5.4).  I have two stansa in dms.sys, each one pointing to 
one of the servers.  I have two opt files, each one poionting to a different 
stanza in the dsm.sys.  I can dsmc -optfile=xxxxx to each of the servers.  How 
do I set up two dsmcad's talking to the two servers, each listening for a 
schedule?
