 
   Problem:
        This user reserved multiple 1/2" cartridge tapes and a 
        potential deadlock situation currently exists.  The 
        requested EVSN is in the ACS but there are no available
        ACS drives to mount it on.
 
   Operator options include:
        -  Deny Request
        -  Use Device Control to make the drive(s) available
        -  Remove the tape from its current ACS and use a
           standalone drive
        -  Remove the tape from its current ACS, place it
           in an accessible ACS, and Resubmit Request to
           the robotic daemon
        -  Wait, the deadlock may resolve itself
