[Veritas-bu] Question posed to ACSLS/STK8500 users.

We have it set to 200.. But sometimes we have issues with netbackup
releasing tapes after backups.  Sometimes the tape stays in the drive for
30-40 minutes, even if we have jobs in queue.
We have logged cases to Symantec about this and also to STK/SUN. But no one
can tells us what`s wrong.

We had similar problems a year back or so. But then the SL8500 was kind new
here and after some firmware upgrades and some new elevators and arms in
place the problem disappeared.

I would also recommend what Mike recommended... In the beginning it was hard
keeping trace of all device names and which drive it was connected to. 

Also check the acsss_event.log to see if there are any errors
mounting/umounting tapes and send them away with the elevator.
