You have -2- processes requesting tapes on DLT1.
Process 144 Migration requests a mount and locks the Drive
Seession 277 (Backup) - is there a file limit sending files directly to
tape? -
              requests a mount but the Drive is locked.
You cann set the MOUNTRetention value short enought, so the tapes can be
dismounted after write  and the MOUNTWAIT value large so the requesting
processes will wait for a mount, but this  will degrade the
transferrate.


Well, what the ADSM-Server should do is not only services the clients,
but optimize the client requests.
