If you can ascertain the cause of the gap, correct the problem
and reply RETRY to the message. If the gap is caused
by HSM backup activity, reply RETRY to message ATR202D
after you get accompanying message ARC0723I.
Note: Replying ACCEPT
to message ATR202D hardens the gap as a data loss to RRS. Internal
flags are set that cannot be updated without a warm start.
When
the gap condition is against the RRS RM.DATA or RESTART log stream
and:
Can be corrected, use an RRS warm start to reset
the internal flag settings.
Cannot be corrected, use an RRS cold start to
recover.
If you cannot find the cause of the gap condition, capture a dump
of RRS and system logger to provide to the IBM® Support Center. Provide the dump along with
SYSLOG and formatted LOGREC data.
