If any hardware failure occurs such as a failed hard disk on the Identity Server machine, you can preserve its configuration and apply it to the replacement machine.
Remove the Identity Server from the Identity Server cluster configuration. (See Removing a Server from a Cluster Configuration.)
Delete the Identity Server from the Administration Console. (See Managing a Cluster of the Identity Servers.)
Uninstall the Identity Server. (See Uninstalling the Identity Server in the NetIQ Access Manager 4.1 Installation and Upgrade Guide.
This is not required when you are using a new machine for the restored Identity Server.
Install the new Identity Server, which imports it into the Administration Console. (See Installing the Identity Server on Windows in the NetIQ Access Manager 4.1 Installation and Upgrade Guide.)
If you have customized login pages, error pages, messages, or configuration files, copy these files to the Identity Server.
Assign the new server to the Identity Server cluster configuration. (See Assigning an Identity Server to a Cluster Configuration
.)
