We run multiple TSM server instances on the same AIX box, but we
don't run them as root.  Instead, we run each one under it's own
userid.  Among other things, this solves the problem of which
server's processes you are looking at.  It also provides an extra
level of data protection to ensure that one server doesn't
accidentally overwrite data on another server.  It's not hard to do -
if you're using raw devices, you'll want to chown them appropriately.

In setting up our first server (AIX) with multiple TSM instances, I realize
that
a "ps -ef | grep dsm" show two processes - and no real way to easily tell
them apart.

   rsfebkup5p.fenetwork.com:/tsmdata/tsm2t/config==>ps -ef | grep dsm
       root  581662       1   0 14:45:41      -  0:03 dsmserv quiet
       root  639052       1   0 10:32:15  pts/0  0:00 dsmserv quiet

My solution was to create to two links to the dsmserv executable
in the install dir (/usr/tivoli/tsm/server/bin) with
different names.

   rsfebkup5p.fenetwork.com:/usr/tivoli/tsm/server/bin==>ls -l dsmserv*
   -rwxr-xr-x   1 root     system     19095507 Feb 21 16:59 dsmserv
   lrwxrwxrwx   1 root     system            7 Mar 30 10:36 dsmserv_tsm2t
-> dsmserv
   lrwxrwxrwx   1 root     system            7 Mar 30 10:37 dsmserv_tsmlm2
-> dsmserv

I then start the tsm servers with the link name.  Now, when I
run a "ps -ef" looking for the dsmserv processes, I get the following:

   rsfebkup5p.fenetwork.com:/usr/tivoli/tsm/server/bin==>ps -ef | grep dsm
       root  581710       1   0 10:37:53  pts/1  0:00 dsmserv_tsmlm2 quiet
       root  946238       1   0 10:38:44  pts/1  0:00 dsmserv_tsm2t quiet

Question:  Is this good/bad . . . has anyone done something similar?

Thanks

Rick
