3698.0. "Mounting tape timeout parameter ?" by PADKOA::COSTEUX (Le Plat Pays qui est le mien...) Wed Mar 19 1997 17:14

    While doing a Backup to a tape the Backup utility mounts the tape (if
    not yet mounted) and if the tape is not ready to mount for any reason
    one get the message:
    %MOUNT-I-OPRQST, Please mount volume XXXX in device _$1$MUA0: ('node_name')
    
    ... and if nobody correct the problem the Mounts hangs forever...
    
    Is there a way to timeout the Mount operation (and abort it) if there
    is no action within a given time to correct the problem ?
    
    I tried to modify the SYSGEN parameter TAPE_MVTIMEOUT but no change
    (i'm not surprised as it's not really the good parameter (if any) to
    change).
    
    Thanks in advance for any comment.

    Hm, not sure what your customer has in mind. Assuming they have only
    one tape device without a loader, why not have BACKUP waiting for
    someone to mount the tape?
    
    One solution is to start a 2nd batch job before the backup command. The
    2nd job just checks that tape mounting progresses. If not take whatever
    action necessary (e.g. run a small program which sends a $FORCEX to the
    backup job to exit BACKUP and proceed).
