Recovering from an Abend of ARCSAEXT Processing

If the space management and backup exit abends, :

Does not process the data set
Stops processing the volume
Holds the function (backup or migration)
Issues message ARC0004I to the system console

does not disable the exit. Analyze the cause of the abnormal end to determine if it is repeatable. If it is, disable the ARCSAEXT exit by issuing the SETSYS EXITOFF(SA) command before releasing the held function (backup or migration).
