Analyzing the ANR1221E error message

When you receive error message ANR1221E, the cause is typically due to insufficient space in the target copy storage pool.

1. Issue the QUERY STGPOOL stgpoolName F=D command.
2. Issue the following SQL select statement from an administrative client to this server: select stgpool_name,devclass_name,count(*) as 'VOLUMES' from volumes group by stgpool_name,devclass_name.
3. Compare the number of volumes reported by the select statement to the maximum scratch volumes allowed (as reported by the QUERY STGPOOL command). If the number of volumes reported by the select is equal to or exceeds the Maximum Scratch Volumes Allowed, update the storage pool and allow more scratch volumes. If scratch volumes are not used in the storage pool (scratch=0), then ensure that you add more private volumes. Issue the UPDATE STGPOOL stgpoolName MAXSCR=nn command, where stgpoolName is the name of the storage pool to update and nn is the increased number of scratch volumes to make available to this copy storage pool.
   Important: The tape library should have this additional number of scratch volumes available, or you need to add scratch volumes to the library prior to issuing this command and retrying the BACKUP STGPOOL operation.
