Verifying the Upgrade Side Before Merging the System
After you have upgraded or installed software on the Upgrade Side, you can perform limited testing on the
Upgrade Side system disks.
Important Before merging system, the following resources are unavailable on Upgrade Side.
You can perform limited testing on the Upgrade Side system disks, as long as your
activities do not require access to the following resources, which are currently
unavailable:
– Network
– External storage
– Data disks
Verification before merging system
•
Verify the presence and version number of each software package
(Refer to
Chapter 1 (8.11 (3) Verifying the Status of Installed Software)
in
Maintenance Guide
.
•
If possible, verify that you can start the applications you installed or upgraded.
•
If possible, configure the settings for any applications you installed or upgraded.
If you are satisfied:
•
You can merge the system to stop your applications on the Production Side and restart them on the
Upgrade Side for final verification.
If there are any problems:
•
You can abort the upgrade to return the system to its original state.
Aborting the upgrade while the system is in split mode will not incur downtime, because your applications
are still running on the Production Side.
(4)
Merging the System
After finishing to perform the upgrade tasks on the Upgrade Side of the system, you can merge the system to
verify your changes before you permanently commit them.
Merging the system:
•
Stops your applications and services on the Production Side.
•
Merges system resources so that the network, external storage, and data disks become available to the
Upgrade Side.
•
Restarts your applications (including the Active Upgrade Console) from the Upgrade Side.
Important If you are using Backup Exec, perform merge process after the system is split and
the OS restarts.
If you do not restart the OS on the Upgrade Side, merge process may fail. If it failed,
press Abort to finish the Active Upgrade. After the Active Upgrade, the duplex
process will be done automatically; after the duplex process is done, retry the Active
Upgrade.
