Summary
2. When the takeovers have completed successfully, examine the EMS event log on
both backup systems for a 735 message to determine which system is missing
audit information.
3. On the system with the least amount of audit information, issue a COPYAUDIT
command specifying the name of the other backup system and its RDF control
subvolume.
4. When the COPYAUDIT command has completed successfully, issue a second
TAKEOVER command on that same system.
5. Initialize, configure, and start RDF on whichever system you want
to be the primary in the new configuration.
6. Start application processing on the new primary system.
