Herb, why don't you use client option sets - that way you don't put
anything into any of the TSM client directories and furthermore, any change
can be done at the TSM server via Web Admin as opposed to having to go to
the client and editing dsm.sys/opt files.

Subject:  Configuring dsm.sys and dsm.opt for multiple clients on one host




Our environment includes an AIX/HACMP cluster.  Some disks are shared,
non-concurrently, by the active and standby hosts. We have configured three
TSM client nodes, one permanently on each host to back up its non-shared
disks, and a third that runs on whichever host is accessing the shared
disks.

In order to do this, we need separate include/exclude lists for the nodes,
which requires separate dsm.sys files.  The TSM 3.7 "Installing the
clients" manual (p.34)  says "Do not put any user created files into
/usr/tivoli/tsm/clients/ba/bin, the directory into which the TSM product is
installed.... Include-exclude files, dsm.opt and dsm.sys files should not
reside in this directory". Later on (p.48) the same manual says that the
DSM_DIR environmnet variable must "point  to the executable file dsmtca,
the resource files, and the dsm.sys file. ... If DSM_DIR is not set, the
executables are expected in the default installation directory."  Sounded
to me like you can;t get there from here.

Our solution was to make a copy of  /usr/tivoli/tsm/clients/ba/bin, put the
second client's dsm.sys and dsm.opt files in there and point to it with
DSM_DIR and DSM_CONFIG.  This works but seems kind of clumsy.  Has anyone
else encountered this problem and found a more elegant solution?

Thanks, Herb
