Recovering from an Abend of ARCTVEXT Processing

If the tape volume exit abends, DFSMShsm:

Disables the exit.
Issues message ARC0502I and records it in the log for the function DFSMShsm has been performing.
If the tape volume exit abends during ABACKUP cleanup processing, DFSMShsm issues message ARC6187E and holds ABACKUP processing after cleanup has been completed.

Analyze the exit to determine if the abend is repeatable. If it is, replace the broken exit with a version that has been fixed. Reenable the exit with the steps described in Installing DFSMShsm Exits.
