DFSMShsm was attempting to back up the volume with volume serial number volser. The BACKUPDEVICECATEGORY parameter was specified on the ADDVOL or BACKVOL command. However, the appropriate type of daily backup volume was not available.
The volume backup operation ends. DFSMShsm processing continues.
Assign additional daily backup volumes of the appropriate type. Retry the backup operation when the additional daily backup volumes have been assigned.
