5-136 Installing and Using Utilities
To split the system
1. Ensure that you have addressed any critical errors or warnings that were indicated by the
readiness check.
2. Exit any non-essential applications.
3. Click Split on the Active Upgrade page.
When the system successfully enters split mode:
•
Active Upgrade Console continues to run on the Production Side of the system.
•
The Active Upgrade Console switches to the Split System page.
•
The upgrade state, reported in the status bar, is Production Side\Split\Ready, indicating that
the system is currently split and ready to be merged after your software installation.
IMPORTANT:
Do not select [Abort] to interrupt the Active Upgrade process. The interruption could fail and the
duplex may not complete. If the interruption failed, restart the OS to finish the interruption normally
according to the following procedures; it enables to duplex the system.
(1) Select the Upgrade Side's PCI module on the ft Server Utility.
(2) Verify if [Status] of the Upgrade Side's PCI module is [Terminate].
(3) Select [Boot] to start the Upgrade Side's PCI module.
(4) Select [Retry] on the Active Upgrade console to finish the interruption process.
Splitting the system should take only a few minutes. The process will time out if it takes longer than
5 minutes.
IMPORTANT:
1. Throughout the upgrade process, icons will appear and disappear in the system tray as
PCI devices, such as Ethernet PCI adapters, are reconfigured or disabled for the current
upgrade operation. This is normal. Do not attempt to enable or reconfigure any of these
PCI devices while the upgrade session is in progress.
2. If your system is running EMC® PowerPath® software for an external storage system,
you might experience a brief delay (10-15 seconds) when the system splits, as PowerPath
reroutes storage operations through the Production Side.
3. If the Firewall setting is not appropriate, the split process could fail. If this occurs, select
[Abort] to terminate Active Update. After the Active Upgrade is finished, automatic
duplex processing is executed. When this duplex processing is completed, execute the
Active Upgrade again.
