I figured out what is happening, but not why it's happening. What is happening is that the TSM instance was started as root via the invocation in the /etc/inittab file, and is allowed to access the raw stgpool vol.
Here is the inittab entry created by TSM install for starting the instance at boot time. This is root running this: ttsmuser:2:once:/opt/tivoli/tsm/server/bin/rc.dsmserv -u tsmuser -i /tsmdata/tsmlm1/config -q >/dev/console 2>&1 # Tivoli Storage Manager My startup script for manually starting the instance was run as root with the same invocation: nohup /opt/tivoli/tsm/server/bin/rc.dsmserv -u tsmuser -i /tsmdata/tsmlm1/config -q & In BOTH OF THESE CASES, tsm is able to access the raw stgpool volume I detailed earlier which should be accessible by the instance owner. BUT, if the tsm instance is started AS THE INSTANCE OWNER HIMSELF, without the "-u tsmuser" parm on the dsmserv invocation, access to the raw stgpool vol FAILS. In other words, if I do the following TSM fails to open the raw stgpool vol: su - tsmuser nohup /opt/tivoli/tsm/server/bin/rc.dsmserv -i /tsmdata/tsmlm1/config -q & ==> Apparently, the inittab style invocation as root with the "-u tsmuser" parm is allowing dsmserv to run with root permissions, even though the actual process is running as the instance owner. . . . interesting . . .
