Google Search Appliance: Configuring GSA Mirroring 11
5. To add a mirror for the current search appliance, type the GSA Appliance ID, Appliance hostname,
Admin Username, and Password under the section Please enter the configuration information
for the node.
If Admin NIC is enabled on the node that you are adding, use the IP address or hostname of the
primary NIC for the Appliance Hostname, click Admin NIC enabled on remote node? and type
the IP address of the remote node’s Admin NIC in Admin NIC IP Address.
6. Check Enable (if not checked by default).
7. Click Done or Add Another Replica.
8. Optionally, click Export and save the mirroring configuration file.
9. On your replica (mirror) search appliance, log in and perform the following steps.
10. Right-click the About link, choose Open in New Tab, and confirm that the replica node is on the
same software version as the master search appliance.
11. Click Status and Reports. The Crawl Status page is displayed.
12. Click Pause Crawl.
13. Click Index > Reset Index.
14. Click Reset the Index Now.
15. Wait until the reset index process has completed and the values under Crawl Status on the
Content Sources > Diagnostics > Crawl Status page are 0.
16. Repeat steps 9 to 15 on each additional mirror node.
17. On the master node, click Apply Configuration on the GSAn > Configuration page. This broadcasts
the configuration data to all search appliances in the GSA n network. Note that document serving
will be interrupted briefly on the master node after you click Apply Configuration.
Because the search appliances in a GSA
n
configuration continuously attempt to re-establish the
connection between nodes, there is no specific action required if you reboot a node or take it offline.
