To troubleshoot when the Crawl or Query component is not responding

1. Launch the SharePoint 2010 Central Administration web page.
2. On the Search Administration page, view the details of the relevant Search service application.
3. Check the Status of the Crawl or Query component.

   If the Status is "Not Responding", perform the following steps.

4. Launch the SharePoint 2010 Management Shell, and execute the following PowerShell script:

   C:\Program Files\Veritas\Cluster Server\bin\SharePointSearch\ SearchServiceAppDetails.ps1

   Provide the application name as input. The script displays the details of the Search service application components.

5. Make sure that the storage for the index location on the Crawl Server or Query Server is accessible.
6. Restart the SharePoint Server Search 14 service.
7. Wait for a reasonable amount of time, and then verify that the component status is Online.
8. Ensure the following for the Query component only:

   • The ShareName attribute of the FileShare resource (for example, SharePointSearch_VM_Query_Share) has the correct value. Compare it with the Name property of the Query component in the output of the PowerShell script.

   • The FileShare resource is online.

9. If the component status is still not Online, then on the CrawlComponent or QueryComponent Server, perform one of the following tasks:

   • If you created the service group manually, restore the registry keys that you backed up before creating the service group or after modifying the Search service application.

     See Configuring a service group for a SharePoint Search service application manually.

   • If you created the service group using the SharePoint Search Configuration Wizard, restore the registry keys that the wizard backed up.

     See Restoring the Crawl or Query component registry keys.

10. Restart the SharePoint Server Search 14 service, and then check the component status again.
