Use the following procedure to configure server switchover settings:
In the RC console resource tree, right-click a server (or a physical OS or VM host on the server) and select [Modify]-[Spare Server Settings] from the popup menu.
The [Spare server settings] dialog is displayed.
In the [Spare server settings] dialog, set the following parameters:
From the spare server list, select the checkbox in the "Selection" column of the server that is to be used as the spare server.
One or more spare servers can be specified, including spare servers from different chassis.
If more than one is specified, an unused spare server will be selected from the list of available candidates when a server switchover occurs.
Information
A server for which any of the operations listed below have been performed is either currently set as an active server or is in the process of being set as an active server. Therefore, it cannot be used as a spare server. However, in configurations in which a spare server is shared between physical OS's and VM guests (using the high-availability feature provided with their server virtualization software), a server running a VM host can be set as a spare server if its status is either "normal" or "warning".
Agent registration
I/O virtualization
Server switchover settings
To change a server with the above settings to a spare server, the server must be deleted and then re-registered. Note that if the server is registered while it is running, an agent will be registered automatically. For this reason it should be registered while it is stopped. For details on server registration, refer to "6.1.3 Registering Managed Servers".
To delete a spare server that has been added, refer to "9.8 Cancelling Server Switchover Settings".
Note
When using the VIOM-based I/O virtualization switchover method, make sure no server profile is assigned to the spare server
This checkbox is available only if the WWN of the servers selected from resource tree is being virtualized using HBA address rename or VIOM.
The checkbox is unavailable if the WWN is not being virtualized or boot configuration is set for a VIOM server profile.
Select this option for servers that boot from a local disk while using SAN storage to store data. If selected, spare server(s) will also be able to boot locally and access the same SAN storage data space after a switchover.
Do not select this option for servers that boot from a SAN disk.
Select this option to enable automatic adjustment of VLAN ID or port group settings during a server switchover. If selected, the internal LAN switch ports connected to the spare server will be set with the same VLAN settings as those of the ports connected to the primary server.
This option is selected by default.
This feature is available only for PRIMERGY BX blade servers.
When VIOM is used, it is available only when a LAN switch is in switch mode.
Note
Do not select this option if VLAN settings are to be manually adjusted from the LAN switch's management interface (either graphical or command-line interface).
Select this option to enable Auto-Recovery.
Server failures are detected when the server's status changes to "error" or "fatal" and its operating system stops functioning.
Do not select this option if primary servers are to be manually switched over.
This option is selected by default.
Click <OK>.
The server switchover settings are configured.
Point
The conditions specified in "9.3 Server Switchover Conditions" must be satisfied for a server switchover to execute correctly.
Once settings are complete, perform switchover and failback on each spare server that has been set up to verify that these operations can be executed correctly.
For details on switchover and failback methods, refer to "Chapter 10 Server Switchover" in the "ServerView Resource Coordinator VE Operation Guide".
[VM host]
The automatic startup of VM guests after the switchover of their VM host depends on their virtual machines' startup configuration within the server virtualization software used.
Refer to the manual of each server virtualization product for details.
According to the server virtualization product used, a newly created VM guest may require some re-configuration before running a server switchover.
Refer to "A.2 Configuration Requirements" for details on such settings.
