Explanation
When DFSMShsm attempted to load an exit to listen
for an ENF, the load failed with abend code displayed.
- If the exit is ENF15, then DFSMShsm cannot detect changes to the
SMS configuration.
- If the exit is ENF64, then DFSMShsm cannot detect dynamic changes
to volume sizes.
- If the exit is ENF72, then DFSMShsm cannot detect over threshold
events for SMS-managed volumes and cannot start on-demand migration.
System action
DFSMShsm processing continues.
Programmer response
Determine the cause of the
load failure based on the explanation of the abend code. If the exit
is ENF72, then enable interval migration until the cause of the failure
is resolved. Correct the cause of the failure and start DFSMShsm again.
