Error description

  • Tivoli Storage Manager servers on AIX with libraries defined
    with RESETDrives=Yes can use two different methods to preempt a
    drive reservation.
    Persistent reserve
    Persistent reserve is used if all of the following 3 conditions
    are true:
      Persistent reserve is supported by the device
      Persistent reserve is enabled on the device driver
      Tivoil Storage Manager server is 6.3 or higher
    LUN reset
    If the conditions are not met for persistent reserve, the server
    completes a reset of the path to the target device.
    When LUN reset fails, the following error message will be
    recorded in the activity log:
      ANR8973E  Device reset failed to break the reservation set
      by another system for device DRIVE1 with path
      /dev/rmt1.
    The server can fail device reset when dsmserv is running as a
    non root user (such as the DB2 instance user ID).  The server
    should be updated to clearly indicate when permissions are not
    adequate for device reset and should provide recommendations for
    performing drive reset.
    Tivoli Storage Manager Versions Affected:
      Tivoli Storage Manager server version 6.1 and above
    KEYWORDS:
    TSM IBM SPECTRUM PROTECT RESETDrives LUN reset
    

Local fix

  • Power cycle the tape drive
      Or
    Configure environment for persistent reserve (if supported).
