Server switchover is a function that enables applications to be switched over to and restarted on a pre-assigned spare server when a primary server fails or needs to be shut down for maintenance.
Server switchover is the basis for the Auto-Recovery function, which is able to automatically switch over applications to a spare server upon failure.
Server switchover settings should be configured before using the server switchover function.
Refer to "Chapter 9 Server Switchover Settings" of the "ServerView Resource Coordinator VE Setup Guide" for details on server switchover settings and an overview of the server switchover function.
Note
When the switchover method is backup and restore
When backing up or restoring system images, or collecting or deploying cloning images, no more than four processes can be executed simultaneously. If four processes are already executing, any system image restore triggered by a switchover or failback operation will enter a wait state. Any process put under wait state will be resumed after one of the already running processes completes.
