What's the device type for the DB backup? We'll see this when SAN discovery hasn't caught up with new device paths after a replacement. The telltale will be ANR8975I messages on the library manager and ANR8974I messages on the clients.
As others noted, though, it can also be an API package problem. It might be fruitful looking in the activity log around the time backups start, along with the db2diag.log and tsmdbmgr.log files.
