Error description

  • The Tivoli Storage Manager server can trigger errors similar to
    the following /var/log/messages and dmesg:
    
      Jun 24 10:08:33 server kernel: lin_tape: IBMtape51----900FE
                      unable to get inquiry page 86
      Jun 24 10:08:33 server kernel: lin_tape: qry_blk_prot cannot
                      get inquiry 0x86
    
    This issue occurs with the lin_tape device driver on Linux
    platforms using IBM tape devices that do not support the
    Logical Block Protection (LBP) feature.  The following TechNote
    describes the drives and firmware levels that *do* support LBP
    (and would not experience this problem):
    
      http://www.ibm.com/support/docview.wss?uid=swg21568108
    
    If you are using IBM drives not listed in the above TechNote
    (for example, LTO3 drives), this problem may apply.
    
    Depending on the number of drives and workload of the
    environment, these errors may be generated hundreds or
    thousands of times per day and flood /var/log/messages.
    
    Customer/L2 Diagnostics:
    None.
    
    Initial Impact:
    Low
    
    Tivoli Storage Manager Versions Affected:
    All 6.2.4+, 6.3.1+, and 7.1 servers on Linux using non-LBP
    capable IBM tape drives.
    
    Additional Keywords:
    TSM LIN_TAPE IBMTAPE TAPE LTO3 LTO2 LTO1 QRY_BLK_PROT LBP
    LOGICAL BLOCK PROTECT PROTECTION INQUIRY PAGE 86 0X86
    

Local fix

  • There is partial relief for this issue in lin_tape 2.9.6+.  At
    that level or higher, the "lin_tape: qry_blk_prot cannot get
    inquiry 0x86" message no longer occurs, however, the "900FE
    unable to get inquiry page 86" message does still occur.
