Restoring the node configuration using a configuration backup file

You restore the node configuration using the configuration backup file that you identified and made available to the recovering node.

1. If the node is healthy, then at the advanced privilege level of a different node, use the cluster modify command with the -node and -eligibility parameters to mark it ineligible and isolate it from the cluster.

   If the node is not healthy, then you should skip this step.

   Example

   This example modifies node2 to be ineligible to participate in the cluster so that its configuration can be restored:

   cluster1::*> cluster modify -node node2 -eligibility false
   
2. Use the system configuration recovery node restore command at the advanced privilege level to restore the node's configuration from a configuration backup file.

   If the node lost its identity, including its name, then you should use the -nodename-in-backup parameter to specify the node name in the configuration backup file.

   Example

   This example restores the node's configuration using one of the configuration backup files stored on the node:

   cluster1::*> system configuration recovery node restore -backup cluster1.8hour.2011-02-22.18_15_00.7z
   
   Warning: This command overwrites local configuration files with 
            files contained in the specified backup file. Use this
            command only to recover from a disaster that resulted 
            in the loss of the local configuration files.
            The node will reboot after restoring the local configuration.
   Do you want to continue? {y|n}: y
   

   Result

   The configuration is restored, and the node reboots.

3. If you marked the node ineligible, then use the system configuration recovery cluster sync command to mark the node as eligible and synchronize it with the cluster.
4. If you are operating in a SAN environment, use the system node reboot command to reboot the node and reestablish SAN quorum.
