Refer to "16.3.2 [Server] Tab" in the "User's Guide for Infrastructure Administrators (Resource Management) CE".
Checks of Spare Server Models and Configurations
The L-Server definition and spare server configuration are checked when configuring server redundancy during creation or modification
of a physical L-Server.
Confirmation is performed on the following items of an L-Server definition and spare server configuration:
-
Server Model
Check if there is a server compatible with the L-Server definition in the specified server pool.
The compatibility of server models is evaluated by the definition file for checks on spare server models and configurations.
The definition file is created when installing managers.
When installing a new compatible server model, update the definition file by adding the server model.
In the following cases, the same server model of physical server as the server specified in the L-Server definition is selected.
