DFSMShsm was attempting to move the backup versions off the migration level 1 volumes, back up any eligible data sets that might have migrated, or create new backup versions from a data set backup command. During the backup operation, DFSMShsm attempted to allocate a daily backup volume to continue the backup operation or to deallocate the daily backup volume that was currently being used for the backup operation. An error occurred in the allocation or deallocation process, and the daily backup volume was not allocated or deallocated properly. The daily backup volume for which the allocation has failed is identified in message ARC0500I.
The backup operation ends. DFSMShsm processing continues.
Notify the storage administrator, who can determine the cause of the allocation or deallocation failure and assign more daily backup volumes if necessary.
None.
