Error description

  • For any tape related operation, the Tivoli Storage Manager
    server does use the real device file to query the persistent
    reserve key of the drive. Due to the current limitation of the
    IBM lin_tape device driver, the Tivoli Storage Manager server
    fails to query the persistent reserve key from a tape drive
    directly. The IBM lin_tape driver sets this query as an invalid
    operation and logs an invalid ioctl to the system log file,
    like:
    
    MMM DD hh:mm:ss vlzdsm1d kernel: lin_tape: lin_tape_drive_ioctl
    invalid ioctl.
    
    This does not affect the Tivoli Storage Manager server
    operations itself nor the usage of the tape device. The lBM
    lin_tape driver only returns the persistent reserve key via its
    pseudo device file.
    
    
    Tivoli Storage Manager Versions Affected:
    Tivoli Storage Manager Server versions 7.1.3 and above on all
    Linux platforms

Local fix

  • None (as these additional ioctl messages can be ignored)
