Resolution

Modifications to the DEFSYS statement require a CA MIM restart with FORMAT=CF. The exception is adding a system to the DEFSYS statement after adding a system dynamically.

When a MIM system is started and joined to MIMPlex without DEFSYS statement definition, MIMPlex assigns system index numbers to INDEX and ALIAS of the MIM.

When a MIM system is started and joined to MIMPlex with DEFSYS statement definition, MIMPlex uses the information to assing the MIM.

Removing a MIM system without MIM control file format, ALTERSYS systemid, STATUS=DISABLE is available.
