Revert to the Original MIMplex

When the new system does not join the MIMplex:

  1. Shut down CA MIM on that system.
  2. Enter the FREE command from one of the active systems.

Once the system has been added with the DEFSYS command, there is no way to remove it. You may need to restore the INIT member to the original state, and perform a global shutdown and control file/checkpoint file format.
