How You Migrate to a DASD Control File

While CA MIM is executing you can migrate to any properly formatted DASD control file that is allocated to all systems in your MIMplex. Migration to a DASD control file occurs in one of several ways:

• From a virtual control file to a DASD control file
• From one DASD control file to another DASD control file
• From a coupling facility structure control file to a DASD control file

To migrate to a DASD control file:

1. Issue the following command to view the list of available control files:

   DISPLAY FILES
   

2. Issue the following command to initiate the migration to a specific file:

   MIGRATE CONTROLFILE=nn
   

   nn

   Specifies the control file ID of the DASD control file

To migrate CA MIM to the next available control file

1. Issue the following command:

   MIGRATE CF
   

Note: When you migrate from a virtual control file to a DASD control file, the virtual control file is deactivated automatically.
