Aborting the Upgrade

If necessary, you can abort the Active Upgrade process and restore the system to its original state at
any point of the upgrade process prior to committing the upgrade.
CAUTION:
You cannot abort the upgrade process after you commit an upgrade because the original state of
the system is lost (overwritten) as a result of completing the upgrade process.
When you abort an upgrade, the Active Upgrade Console:
•
Cancels the current Active Upgrade operation.
•
If applicable (and if your system is in the merge state), initiates a system restart. It shuts
down the Upgrade Side and restarts the system from the Production Side, which automatically
restarts your applications from your original Production side system disks.
•
If applicable, reestablishes the mirror of any internal RDR system disk by overwriting the
upgraded partner disk with the original partner disk.
•
If applicable, reestablishes the mirror of any internal RDR data disk by overwriting the stale
partner disk with its newer, live partner disk (the disk to which your applications have been
writing data throughout the upgrade process).
•
If applicable, bring the Upgrade Side online to enable fault-tolerant, duplex mode.
To abort an upgrade, click the Abort button on the Active Upgrade page, the Split System page, or
the Merge System page.
IMPORTANT:
Your screen might flicker and you might briefly lose control of your keyboard and mouse as the
system recovers its original state.
The abort process should take only a few minutes. When the process completes, the upgrade state is
Fault Tolerant\Abort\Ready. You can click Finish to clean up ftServer resources, as described in
"Finishing the Upgrade" on page 5-157.
If the abort process fails the first time, you can click Retry to try again. If the problem persists, see
"Troubleshooting" for information about resolving the problem.
