Use the following procedure to switch applications over to a spare server and replace a server with minimal interruption.
1. Perform Server Switchover
Switch over the server to replace with its spare server.
For server switchover, refer to "Chapter 4 Server Switchover" in the "Operation Guide VE".
The server to replace is automatically powered off after switchover.

Change the BIOS settings of the replacement server to match the operating environment.
For details on BIOS settings, refer to "8.2 Configure the Server Environment" in the "Design Guide CE".
Shut down the server after completing BIOS settings.
Configure the remote management controller of the replacement server with the same IP address, user name, password, and
SNMP trap destination as those set on the original server.
