749.0. "UNICENTER locking tape" by RHETT::LAROSE () Fri Jun 06 1997 05:28

    FYI, watch out for UNICENTER locking the tape robotics.
    
    A customer experienced the following problem at NSR V3.2A
    while using a TZ877 sequential loader:
    
    Symptom:
    NSR wrote to tape fine, but when tape is filled NSR gave the
    pending message without ejecting and going to next tape.  But,
    on occasions it would eject fine.
    
    Eventually the customer did the file command and saw the following
    information:
    
       # file /dev/nrmt1h
       *ENF*CAIENF_F_0141 07:26:48.419 NOT YOURS: dev /dev/nrmt1h
        mounted by uid 0 and pids 1059, 0, 0, 0, 0
    
    Solution/Analysis:
    The customer had installed UNICENTER and the NSR tape drive was
    enabled in UNICENTER's tape management facility. He didn't recall
    setting this up and believes UNICENTER did it automatically. His
    solution was deinstalling UNICENTER, which he didn't need.  The 
    drive could probably be disabled in the tape management facility.
