ARC1254I

Explanation
 The ARCMDEXT exit for migration
processing, ARCADEXT exit for data set deletion or data set retirement
processing, or the ARCMMEXT exit for second-level migration processing
ended abnormally (abended). DFSMShsm has placed a hold on the migration
function so that no migration or data set deletion commands can be
processed until the hold is removed by using the DFSMShsm RELEASE command.

System action
 DFSMShsm processing continues without the
migration function.

Operator response
 If you determine that the DFSMShsm migration function
(migration and data set deletion) can process without the installation-wide
exit, using the SETSYS command with the EXITOFF parameter, turn off
the installation-wide exit, and release the migration function.  Note: If
the ARCADEXT exit abends and you turn off the exit and release the
migration function, DFSMShsm might delete data sets that the
exit would have kept.

Programmer response
 Correct the cause of the abend, and relink
the exit module. The exit can be reactivated with a SETSYS command.
