Error description

  • Backups can fail with "ANR0530W Transaction failed for session
    12345  for node <Node_Name>  - internal server error detected.
    (SESSION: 12345)" when writing to a disk storage pool with cache
    enabled that is full, and where cache space needs to be
    deallocated to allow space for the data to be written. This
    happens when multiple clients request space to be deallocated at
    the same time. A full cache is when a disk storage pool has Pct
    Util as 100% but Pct Migr is less than 100%.

Local fix

  • Disable cache for the disk storage pool. First, update the
    stgpool to have cache=no. This alone does not disable caching.
    You need to run move data for each volumes to new or empty
    volumes, or delete the volumes and create new ones.
