Verifying The Upgrade Side Before Merging The System - NEC NovaScale R630 User Manual

CAUTION:
Any changes you make to files on the Production Side system disks will be lost during the commit process, because
the system overwrites these system disks (which contain the old version of your software) with the newer Upgrade
Side disks to complete the upgrade. If you need to preserve files from the original system disks, you can save them to
a data disk.
NOTE:
Be careful when switching between the Production Side desktop and the remote connection to the Upgrade Side desktop.
When you resume software installation or restart the system, always ensure that you are on the Upgrade Side.
TIPS:

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, as long as your activities do not require access to the following resources, which are currently
unavailable:
Network
External storage
Application data disks
For example, you might want to perform the following tasks before you merge the system:
Verify the presence and version number of each software package (see "Verifying the Status of Installed Software"
on page 5-131).
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 that everything is working correctly, 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 critical applications are still running on the
Production Side.
