3. When you are done installing software on the Upgrade Side and you start the merge process,
the Active Upgrade Console switches to the PrepareMerge state, during which it runs
additional readiness tests and background tasks. If the system is ready, the console immediately
switches to the Merge state and restarts your applications on the Upgrade Side.
4. When you are satisfied that everything is working correctly and you start the commit process,
the Active Upgrade Console switches to the Commit state, during which it starts the
resynchronization of your RDR disks. You can subsequently start the finish process, during
which the Active Upgrade Console switches to the Finish state, cleans up system resources,
and then returns the system to the Idle state. The upgrade session is complete.
If necessary, you can abort the Active Upgrade process from the PrepareSplit, Split, PrepareMerge,
and Merge states. When you abort the upgrade session, the Active Upgrade Console switches to the
Abort state, during which it restores your system to its original configuration and starts the
resynchronization of your RDR disks. You can subsequently initiate the finish process, as you
would after committing an upgrade.
Alternatively, you can retry any of the Active Upgrade states to recover the system from a transient
failure and move on to the next states without aborting the entire Active Upgrade process.
All of these Active Upgrade states are reported in the activity log and status bar of the Active
Upgrade Console during the upgrade process. See "Understanding the Active Upgrade Console
Interface" on page 5-104 for more information.
