My client is studying the implementation of a SAN. And on top of that there will
be two SAN's in two different places to be able to create a DR site. What my
client is asking is to study if it is feasable and thinkable to do the backups
on the two different SAN's (with tape robot and necessary TSM Servers)
alternatively ie one day at TSM server 1 the other day to server 2.

In my idea it is the dsm.opt or the dsm.sys which directs the client to the
server. Alternating to the two TSM servers would mean updating these files and
restarting the client every day. Not forgetting the difficulty to figure out to
which TSM server to connect to restore a file of a few days ago not knowing by
which server it has been backed up.

Does anyone see a possible configuration to fullfill my client whishes? Any
comment is appreciated.
