The query shows there is only 1 active backup task. We think we've figured
out what is happening. We have INUSE(RETRY(Y) DELAY(0) SERIALIZATION
(PREFERRED) coded so HSM was allocating a second drive to back up datasets
that were in use after the initial backup task completed.

Visnson,
When you have MAXBACKUPTASKS=01, and you are seeing multiple drives
mounted, what does a Q AC display show as active tasks.

Er Jay, We're talking about tape drives here.
1 Backup Task should have 1 DASD unit as input and 1 Tape unit as output.
The OP specified Duplexing was turned off

Unfortunately, we're still running z/OS 1.7, so IBM will not allow us
to open
a PMR for this issue. We are a small shop and do not have a lot of
tape
drives available and are trying to minimize
OS- z/OS 1.7 put RSU0809
DFHSM SETSYS MAXBACKUPTASKS(1) and DUPLEX BACKUP(N)
When AUTOBACKUPSTART DFHSM is allocating two tape drives. Even though
the Setsys is set to MAXBACKUPTASK (1).
Any ideas why?
