Recovering from an Abend of ARCRDEXT Processing

If the recall exit abends, DFSMShsm

Does not recall the data set
Holds undirected recalls
Does not hold directed recalls
Issues message ARC0004I and records it in the migration activity log
Stops returning volumes to JES3 for setup, and JES3 setups that refer to migrated data sets end in error

DFSMShsm does not disable the exit. Analyze the cause of the abend and determine if it is repeatable. If it is, disable the ARCRDEXT exit by issuing the SETSYS EXITOFF(RD) command before releasing recall and JES3 setup.
