My site has a number of HP-UX Oracle servers. We used to send
incoming backups to storage pools composed of sequential disk volumes
(which TSM treats like tape volumes with respect to mount points
and mount point limits), and data for Oracle restores is almost
always read from tape. We started off setting maxnummp equal to the
number of backup or restore streams TDP was configured for, and
got lots of sessions failing with messages indicating that the client
was trying to use too many mount points. We eliminated the problem
by setting maxnummp to twice the number of streams TDP was
configured for. We have never figured out why the extra mount points
are needed.
