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.
-
Click Break.
