The CA MIM Health Check is showing an exception for one of the control files. How is this to be handled?

More verbose information regarding the health check can be reviewed for recommended actions.
This can be done using SDSF (ck) or CA SYSVIEW (hc) commands. For this specific health check, the following information is presented.
* Medium Severity Exception *
The allocated CA MIM control files have been evaluated and
errors have been found.
Explanation: The allocated CA MIM control files have been evaluated
on system XE03 and errors have been found.
System Action: The system continues processing.
Operator Response: Report this problem to the system programmer.
System Programmer Response: View the 'CA MIM Control File Status
Report' above. This will help you identify the CA MIM control file
that has been marked in ERROR.
The Status Report will also help you determine the DDNAME and DSNAME
values of the control file in ERROR. These values will be needed
for the CA MIM DEALLOCATE and ALLOCATE commands which will be
executed to clear the ERROR flag.
The DDNAME value is formed by using 'MIMTBLnn', where nn is a
two-character numeric File ID value from the Status Report. The
DSNAME value is formed by using the actual Data Set name value from
the Status Report.
For example, if the Status Report shows that DASD control File
ID=00, Data Set name=MIM.PRIMARY.CF is in ERROR, the following
series of CA MIM commands could be executed to clear the ERROR flag
and return the file to a USABLE state:
1. DEALLOCATE DDNAME=MIMTBL00
2. DISPLAY FILES
(verify File ID=00 is not in the display.)
3. ALLOCATE DDNAME=MIMTBL00 DSNAME=MIM.PRIMARY.CF
4. DISPLAY FILES
Verify File ID=00 is shown in the display with the proper Data Set
name, and has a Status of USABLE.
If the control file in ERROR is a coupling facility list structure
control file, instead of using the "MIMTBL00" parm above, one would
use the "XESFILEID=00" parm, and instead of using the
"DSNAME=MIM.PRIMARY.CF" parm one would use the
Once the control file ERROR flag has been cleared and the file has
been restored to a USABLE state, [email protected] should
be rerun to verify that the ERROR exception has been cleared.
Because control file states are from the local system point of view,
once you have cleared the ERROR flag on the local system, you will
want to verify the health of the control files on all other systems
in the MIMplex.
