Error description

  • Cleaning drive operation can be invoked unexpectedly while drive
    operation such as mount/dismount running on Tivoli Storage
    Manager server or Storage Agent.
    The situation can occur when the "cleanFrequency" option for
    the drive definition is set to "gigabytes" or "asneeded" on
    Windows platforms.
    Even when the amount of bytes written does not reach the
    gigabytes set or there is no valid request from H/W, Tivoli
    Storage Manager server mistakenly interpret SENSE code from
    drives and judge that drive cleaning should be made.
    
    Tivoli Storage Manager Versions Affected: All supported versions
    on Windows platform.
    
    
    Customer/L2 Diagnostics (If Applicable)
    When collecting the results of "show library" commands for every
    few minutes, it can be seen that needsCleaning flag become "1"
    even though the value of KBytesProc does not exceed the value of
    CleaningFreq or though there has not been H/W cleaning request.
    
    Here will be seen in the result of "show library" command.
    ---------------
    CleaningFreq(GB)=XXXXX, KBytesProc=YYYYY, needsCleaning=1.
    
    
    Initial Impact: Middle
    
    Additional Keywords: zz55 zz61 zz62 zz63 cleanFrequency
    needsCleaning clean drive
    

Local fix

  • To avoid the problem, set cleanFrequency option to "none" with
    "update drive" command.
    When the value is set for the option, drive cleaning operations
    which are invoked by H/W should be suppressed.
