This chapter explains how to use server switchover settings and automatically recover from server failures.

Current recovery settings can be confirmed by selecting a physical OS or VM host in the server resource tree of the ROR console and
from the spare server settings displayed in the [Resource Details] tab.

The following information is displayed:

Primary server

Displays the name of the physical server that will be replaced when server switchover occurs.

Active server

Displays the name of the physical server that is currently running.

Server switchover method

Displays the specified server switchover method.

Automatic server recovery

Shows whether automatic server recovery is enabled or not.

Network switchover

Shows whether network settings will be automatically adjusted during server switchover.

Spare server

Displays the name of the physical server that will replace the current active server when server switchover occurs.
More than one spare server will be displayed if more than one has been specified.

Use the following procedure to configure server switchover settings:

When using local disks as system disks, and iSCSI storage as data disks, refer to the advisory notes described in "Table 8.1 Supported
Storage Device Configurations" in "8.1.1 Storage Configuration" in the "Design Guide VE".

1.

In the ROR console server 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.

2.

To use this feature, the following settings must first be defined:

Spare server

From the spare server list, select the checkbox in the [Select] 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

For SPARC Enterprise servers, only the storage affinity switchover method can be selected. In the storage affinity switchover
method, configuration of WWN information is necessary. For how to configure WWN information, refer to "10.1 Configuring
WWN Settings for ETERNUS SF Storage Cruiser".

When using the storage affinity switchover method, it is necessary to configure the target CA so that it matches the WWPN
value in the access path settings of the primary server.
