An error occurred while DFSMShsm was creating a new entry in the DFSMShsm control data set or updating an existing entry. Message ARC1001I precedes this message, where reascode is the return code indicating the type of failure. For reascode values, see Table 6.
The operation ends. DFSMShsm processing continues.
Notify the storage administrator. If reascode is 4, 8, or 12, correct the problem, possibly using the FIXCDS command. If reascode is 16, an I/O error is the normal cause, and an error message from the ERPs should be found in the DFSMShsm job log SYSMSG data set. If reascode is 20, an internal DFSMShsm error occurred. If reascode is 21, a retained backup copy was encountered. Retained backup copies can only be processed on a z/OS® V1R11 or later system.
