It may be necessary to break an xHA pair, for example, to troubleshoot issues on each node separately. Whenever you break an xHA pair, you should verify that all services provided by the new standalone server are operational before the server re-enters full production.
Breaking an xHA pair returns each server to its original stand-alone state, so they appear on the Servers tab as individual servers. The server that held the active role remains connected to Address Manager, while the server that held the passive role is disconnected and has HA-NODE2 appended to its name. Each server is re-assigned its original IP address.
To break an xHA pair:
- Select the Servers tab. Tabs remember the page you last worked on, so select the tab again to ensure you're on the Configuration information page.
- From the configuration drop-down menu, select a configuration.
- Under Servers, click the xHA pair.
- Click the menu beside the xHA pair name and select Break.
Review the information in the xHA and Break
Options sections of the page:
- The xHA section lists the name and server profile of the xHA pair and the types of servers in the pair.
- The Break Options section lists the individual servers, their connection status, their active or passive state in the pair, and their IP addresses. If Dedicated Management is enabled, this section lists the IP address of the Management interface (eth2).
- If the xHA pair cannot be broken, select the Break xHA configuration in Address Manager interface only check box. This option breaks the xHA pair in Address Manager even if the xHA settings are not removed on the actual servers.
- Under Change Control, add comments, if required.
Note: If you can't break the xHA pair, contact BlueCat Customer Care.
