Error description

  • Lanfree backup to a virtual tape library,  where libtype=VTL,
    that does not properly emulate the drive feature Append-Only
    mode, can fail with:
    
    ANR8302E (Session: 26, Origin: STANAME)  I/O error on drive
    DRIVE0 (/dev/rmt0) with volume 123456L5 (OP=ALLOWOVERWRITE,
    Error
    Number=22, CC=0, rc = 1, KEY=05, ASC=24, ASCQ= 00)
    
    
    This same failure can also be seen on the server if the library
    is defined as a SCSI library type.
    However, if the library is defined as a VTL library type on the
    server, the error will not surface,
    because the server incorrectly fails to utilize the drive
    feature Append-Only mode.  Please note
    that if the virtual tape library correctly emulates the
    Append-Only mode, there is no issue
    regardless of configuration.
    
    
    
    VTL's that do not emulate or support the Append-Only feature
    need to use
    TSMONLY for the CHECKTAPEPOS option on all servers and storage
    agents
    using the library.
    
    
    
      Tivoli Storage Manager Versions Affected: 6.3.x
      Initial Impact: Low
      Additional Keywords: TSM
    

Local fix

  • Set CHECKTAPEPOS option to TSMONLY on all servers and storage
    agents
    using the library.

Problem conclusion

  • This problem was fixed.
    
    NOTE: When this fix is applied, the LOCAL FIX may still need to
          be applied until the VTL library correctly emulates the
          Append-Only mode drive feature.
    
    Affected platforms:  AIX, HP-UX, Solaris, Linux, and Windows.
