Error description

  • Tivoli Storage Manager Server may fail to dismount a cartridge
    from a tape drive when the Logical Block Protection (LBP) option
     is enabled. The ANR8302E and ANR8355E messages
    do show up at the server console.
    ANR8302E I/O error on drive <drive name> (mtx.x.x.x) with
    <volume name>
    (OP=SETMODE, Error Number=6, CC=207, rc =2863, KEY= 05, ASC=1A,
    ASCQ=

    in a state capable of performing request). Refer to the
    Tivoli Storage Manager documentation on I/O error
    code descriptions.   (PROCESS: 2)
    
    ANR8355E I/O error reading label for volume
    <volume name> in drive <drive name> (mtx.x.x.x). (PROCESS: 2)
    
    
    Customer/L2 Diagnostics:
    The problem is in the Logical Block Protection function that can
    cause Tivoli Storage Manager device driver  to use an incorrect
    data length for the SCSI mode select command.
    In this case the data length is related to the tape medium
    format and the setmode command is unable to interpret it
    correctly when the Logical Block Protection is enabled on the
    tape drive itself.
    Gathering a PVR MMS DDTRACE will shows:
