I know this is a different product but it uses and OBSI module which specifies "ADSM" instead of tapes or drives. The "mount points" needed, thus, are not directly attibutable to the tape or drive resources available but seem to represent communication threads available. During testing, we found that sometimes backups would work with 1 mount point, they would work most of the time with 2 and work all the time with three. Hope this info is of some help.

Re: SQL-Backtrack and multiple tapes
Hallo thanks all for your help. Redefining the storagepool to filespace-based collocation and changes in the pool defs of SQL-BT has fixed the problem. Greetings from Hamburg Rolf Meyer SATISFACTORY Info Business Systems GmbH

Rolf What is your device class mount limit?

Re: SQL-Backtrack and multiple tapes
I use TSM 4.1.2 on Solaris 8 with BMC SQL Backtrack for Oracle. Trying to do a backup of a 300G SAP DB using more than one backup stream. SQL-BT starts two sessions to TSM, one gets a tape from 3494 lib, other stays on MediaW. Both stream go to same Managementclass/Storage Pool. How should I configure TSM to let SQL-BT writing to more than one tape. We have done this successfully. We configured SQL-BackTrack so that it would use a different prefix for the filespace names created by each stream, and configured the TSM storage pool for collocation by filespace (as opposed to collocation by node).
