What I do an it may take up more space but it gives me a little more
flexibility is I have
/usr/tivoli/tsm/tsmsvr2
/usr/tivoli/tsm/tsmsvr4
/usr/tivoli/tsm/server

I keep a copy of everything regarding each machine in it's own directory
tree including the code.  Then I have a rc.adsmserv2 and rc.adsmserv4 to
start each.  This helps me to upgrade one server and not the other.
Hope this helps
