Error description

  • A Tivoli Storage Manager server may calculate the "PCT Migr"
    value incorrect. The value will be too low until the Tivoli
    Storage Manager server is rebooted.
    As the value is not calculated in the correct way, threshold
    based migration will not take place.
    
    
    Customer/L2 Diagnostics:
    Collect the "show sspool" output and trace the "q stg <poolname>
    f=d" command using the SSPOOL traceflag.
    
    You are affected by the APAR when the NumEmptyVols value in the
    "show sspool" output is higher then the NumDefVols value
    and differs from the corresponding empty vols value in the
    trace:
    ...
    [asutil.c][1737][AsGetPoolStatus]:used cap 32283305454347, used
    vols 40, total vols 68 empty vols 0 scratch 80
    ...
    
    show sspool:
      -> Pool VTL(15): Strategy=30, ClassId=13, ClassName=LTO,
            ......
            AS Extension: NumDefVols=40, NumEmptyVols=48,
            NumScratchVols=40, NumRsvdScratch=0
    
    Tivoli Storage Manager Versions Affected:
    Tivoli Storage Manager 6.3
    
    
    Initial Impact:
