Error description

  • Reclamation is completing without processing all of the volume
    which is eligible
    for being reclaimed based on the Pct. reclaimable space for the
    volume.
    ANR1804W is genereated for the volume which is eligible for the
    reclamation.
    Following is the possible senario when the problem occurs.
    
    1. In storage pool A there are 2 volumes (VOL1, VOL2) which are
    eligible for a reclamation, and 10 empty volumes.
    2. Run reclaim stgpool against storage pool A.
    3. VOL1 is opened as input volume, and VOL2 is opened as output
    volume.
    4. After the reclamation completes for VOL1, VOL2 is requested
    as input volume, and ANR1804W occurs because it was used as
    output volume.
    
    actlog shows following message:
