Every Monday morning at 8:30, I run this scheduled command:

        mov drm * wherest=mo tost=cou s=dbno

An operator removes the cartridges form the 3494 I/O convenience station
and sends them off to the vault.  But the command "q drm" issued
immediately after the move process completes always looks something like this:

UC0986             Vault               10/08/2001 09:36:46
UC0987             Vault               10/08/2001 09:36:46
UC0988             Vault               10/08/2001 09:36:46
UC0989             Vault               10/08/2001 09:36:46
UC0904             Mountable           10/15/2001 07:01:12   TSMLIB
UC0901             Mountable           10/13/2001 07:01:26   TSMLIB

There seem to always be 2 or 3 cartridges that don't get moved and remained
in the "mountable" state for the rest of the week.

Can anyone tell me what is going on here?
