Error description

  • Data movement out of a deduplication storage pool may fail
    with resource waiter abort and lock conflict. This may affect
    the MOVE DATA and MIGRATION processes. For example, in the case
    of migration from a deduplication pool, the following errors
    may be logged in the Tivoli Storage Manager activity log :
    
    ANR0538I A resource waiter has been aborted.
    ANR1130E Migration is ended for volume <volume_name>.
     There is a lock conflict.
    ANR1029W Migration process nn terminated for storage pool
     <stgpool_name> - lock conflict.
    ANR0985I Process nn for MIGRATION running in the BACKGROUND
     completed with completion state FAILURE at <timestamp>
    
    Customer/L2 Diagnostics:
    A TSM server trace (AF DEDUP) will show the following errors :
    
    <timestamp> [xx][aferase.c][632][AfDeleteBitfileFromPool]:
     Error locking deref chunk table.
    <timestamp> [xx][afmove.c][6023][MoveCluster]:
     MoveBatch returned rc=82.
    
    Diagnostic show commands will show a transaction holding
    the "bf deref chunks" lock. For example :
    
    Show txnt :
    
    Tsn=0:nnn, Resurrected=False, InFlight=True, Distributed=False,
      Persistent=True, Addr 4a80738

      Participants=1, summaryVote=ReadOnly
      EndInFlight False, endThreadId 20, tmidx 0 0,
      processBatchCount 0, mustAbort False.

          DB: --> OpenP=... for table=BF.Dereferenced.Chunks.
          DB: --> OpenP=... for table=BF.Queued.Chunks.
      ...
      Locks held by Tsn=0:nnn :

    Other symptoms include the following error :
