DASDONLY or CTCDASD Formatting

If the following are true:

• The GMR resides in the DASD control file or coupling facility structure.
• Checkpoint files are not required, and you are using the DASDONLY or CTCDASD communication method with the REQUEUE feature of ECMF not active.

Then do the following:

1. Stop CA MIM on all systems in the MIMplex by issuing the following command:

   @SHUTDOWN,GLOBAL
   

2. Start CA MIM on the first system by issuing the following command:

   S MIMGR,FORMAT=CF
   

3. Start CA MIM on all other systems normally by issuing the following command on each system:

   S MIMGR
   

If checkpoint files are required, and you are using the DASDONLY or CTCDASD communication method with the REQUEUE feature of ECMF active, us the following procedure:

1. Stop CA MIM on all systems in the MIMplex by issuing the following command:

   @SHUTDOWN,GLOBAL
   

2. Start CA MIM on the first system by issuing the following command:

   S MIMGR,FORMAT=BOTH
   

3. Start CA MIM on all other systems normally by issuing the following command on each system:

   S MIMGR,FORMAT=CKPT
