Under normal operation, xHA automatically fails over in the event of a hardware, network or service failure related to the Active node. However, you can perform a manual xHA failover for maintenance or verification purposes.
When you perform an xHA failover manually, the roles of the servers in the xHA pair are reversed: the Passive server becomes the Active node, and the formerly active server becomes the Passive node.
If a server is disconnected, the Failover function is unavailable for use.
To perform an xHA failover:
- 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 xHA pair name menu and select Failover.
Review the information in the XHA and
Failover sections of the page:
- The XHA section lists the name and server profile of the pair.
- The Failover 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 IPv4 address of the Management interface (by default, eth2).
- Under Change Control, add comments, if required.
- Click Failover.
