DFSMShsm issued the OPEN macro to open either the data set that is to migrate or the SDSP data set that contains the migrated data set. During OPEN processing, the ESTAE routine was invoked. An OPEN error message with component identifier IEC normally precedes this message if this is a true OPEN error. The preceding message ARC1001I or associated message ARC0734I gives the name of the data set that was being migrated.
The migration operation of the data set ends. DFSMShsm processing continues.
Take the action indicated by the OPEN error message. If the data set cannot be opened, recover the data set from a suitable backup version.
