DFSMShsm issued the OPEN or CLOSE macro to open or close either an output data set or the SDSP data set during a migration operation. During OPEN or CLOSE processing, the ESTAE routine was invoked. An OPEN or CLOSE error message with component identifier IEC precedes this message. Message ARC1001I or the associated message ARC0734I gives the name of the data set that was being migrated.
Reason code 1 indicates that WORM tape is not supported for this function.
The migration operation of the data set ends. DFSMShsm processing continues.
Take the action indicated by the OPEN error message. Issue a command to cause migration of the data set if forced migration is required.
