What was the actual action CA-DISK was performing to trigger the error?
Why does an ACF2 failure of CA-Disk merges cause data loss?
This user had the authority for deletion of the volumes from TMS...
TMSTMSTV-00 QS7831 EXPIRE COMPLETE - EDMID=SAMS .
However, the ACF2 violation was when CA Disk was trying to remove the catalog entry that the user was not authorized to do.
ACF99913 ACF2 VIOLATION-08,05,xxxxxx,ARCIVE,xxx.xxx.xxx
ACF95913 -AMS/CATALOG FUNCTION SUPPRESSED; AUTHORIZATION IS REQUIRED.
MERGE does perform IXMAINT type activity, along with Merging unexpired data to new tapes.
That is... If a data set on the input tape qualifies to be expired,
Merge will delete it rather then move a "dead" data set forward to a new tape.
MERGE will not do RE-catalog action during a Merge.
But, if Merge will remove an expired data set, it will UNCATALOG that data set.
So, don't jump to think that a real data set was wrongly deleted.
The ACF2 log for the user would show the error and the action being attempted.
The ACF2 administrator should be able to provide the user the proper access.
