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%. . .

Tivoli Storage Manager Versions Affected: Tivoli Storage Manager 6.1.3.x on all supported platforms. . . Initial Impact: High . . Additional Keywords: TSM zz61 cache internal error
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.
