Have you tried the following first?
DSPTAP ... ENDOPT(*UNLOAD)
Failing that, have you tried the web interface to the management port on the back of the tape library to move tapes around?  I used that quite frequently.

Subject: How to unload a stuck tape on a 3573 LTO7 Half Height drive
I have a LTO7 volume that will not unload from a 3573 tape library.
These are half height drives.
The volume actually got stuck on the load, nothing written.
I remember on the 3582 FH drives, there was a button  you could hold in that would force a unload.
I'm note finding/seeing that same button the 3573 HH.
Any thoughts from the group.
Thank You
