# Validating a cluster

Note: You cannot use this action in startable-CD mode or when using the ServeRAID Manager as a plug-in application.

Use this action to determine if your cluster configuration is configured correctly.

1. In the tree, click (system).

2. Right-click Validate cluster. The "Validate cluster" window opens. The system you selected in step 1 is listed in the Node A box.
   Note: You cannot change the Node A system in the "Validate cluster" window. To select a different system, click Cancel to return to the tree.

3. Select your second system from the Node B drop-down list.
   Note: The Node B system defaults to the first system in the tree other than the Node A system. If there are no remote systems in the tree, click Cancel to return to the tree and add a remote system.

4. Click Start. The ServeRAID Manager scans both systems to verify the configuration. The progress indicator reports the progress of the validation.

5. If you want to stop the validation before it is completed, click Cancel. Otherwise, if the ServeRAID Manager found problems with the configuration, it reports the problems in the message field. If there are no problems with the configuration, the message field reports only the cluster pairings found.

6. To view the problem report events in an easy-to-read window, double-click an event in the message field.

7. To save the contents of the message field, click Save. A "Save as" window opens.
8. Specify the file name for the message field log and click OK.

9. Click Done to exit the "Validate cluster" window. If the configuration has problems, use "Configure for clustering" to fix the problems; then, use "Validate cluster" again.
