## Validating a cluster

Use this action to determine if your cluster configuration is correctly configured. This action is not available in startable-CD mode or when the ServeRAID Manager is a plug-in for another program.

1. Click a system from the Main Tree.

2. Click Actions --> 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 Main Tree.

3. Select your second system from the Node B drop-down list box.
   Note: The Node B system defaults to the first system in the Main Tree other than the Node A system. If there are no remote systems in the Main Tree, click Cancel to return to the Main 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 completes, 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. Specify the file name for the message field log and click OK.

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