During the ABACKUP of a migration level 2 (ML2) data set, an attempt was made to update the MCV_FABACKUP flag (volume in use by ABACKUP) of the MCV record associated with the ML2 volume on which the data set resides. The update of the MCV failed.
volser indicates the ML2 volume on which the data resides.
agname indicates the name of the aggregate group being processed.
Aggregate backup fails.
When the cause of the MCV update error is corrected, reissue the ABACKUP command.
