Error description

  • If during Tivoli Storage Manager storage pool migration a volume
    is identified to be processed by a REPAIR STGVOL process, this
    might fail with ANR4759E.
    
    The activity log will report a sequence like:
    ANR1100I Migration started for volume <volume>, storage pool
      <poolid> (process number <number>). (SESSION: <migration
      sessionid>, PROCESS: <processid>)
    ANR1102I Removable volume <volume> is required for migration.
      (SESSION: <migration sessionid>, PROCESS: <processid>)
    ANR0984I Process 747 for REPAIR STGVOL started in the BACKGROUND
      at <time>. (SESSION: <repair sessionid>, PROCESS: <processid>)
    ANR4752I REPAIR STGVOL process 747 started for 1 volumes.
      (SESSION: <repair sessionid>, PROCESS: <processid>)
    ANR1101I Migration ended for volume <volume>. (SESSION:
      <migration sessionid>, PROCESS: <processid>)
    ..
    ANR4759E REPAIR STGVOL failed to process <volume>. (SESSION:
      <repair sessionid>, PROCESS: <processid>)
    
    The symptom is caused by migration leasing a volume for
    processing, and the lease not being freed before the REPAIR
    command is invoked.
    
      Tivoli Storage Manager Versions Affected: all V6 servers
      Customer/L2 Diagnostics (If Applicable)
    A trace with tracflag REPAIRVOL shows the following
    messages:

    Failure leasing volume.

    [22469][ssalloc.c][2692][DoRepairStgVols]:DoRepairStgVols:
    Exiting with rc 155.
    
    RC 155 translates to SSRC_VOLUME_ALREADY_LEASED
    
    SHOW SSL will report
      Volume <volume>(<volumeid>) --> Mode=Access, PoolId=15,
    Strategy=30, SessId=<migration sessionid>, Tag=4
      Initial Impact: Low
      Additional Keywords: REPAIR STGVOL TSM ZZ61
    
    Reclamation can also show this same condition.
    
    Platform/Version affected:
    
    Tivoli Storage Manager Server V55 V61
    

Local fix

  • Manually run the
    REPAIR STGVOLS VOLName=<volumename>
    while there is no lease (SHOW SSL) active for the volume.
