Under normal operation, xHA automatically fails over to the passive node in the event of a hardware, network, or service failure related to the active node. However, you can initiate a manual xHA failover for maintenance or verification purposes.
Warning: BlueCat advises
customers to never perform a manual xHA failover immediately after modifying the
network and interface configurations of an xHA pair (such as the xHA backbone,
additional IP service addresses, or VLAN interfaces). Doing so can result in loss of
the modified data. If the manual xHA failover must be performed after changing
interface or network configurations, allow several minutes for the data to
synchronize between the Active and Passive nodes of an xHA pair before performing
manual xHA failover. For more information, refer to the Knowledge Base article on BlueCat Customer Care.
To initiate a manual xHA failover:
- Navigate to .
- Select the active xHA node in the data grid.
- Use the Action menu to select Trigger xHA failover.
- In the dialog, select Yes to confirm you want to initiate the failover.
When you initiate manual xHA failover, the dialog displays a loading indicator until the failover process is complete.
xHA failover reverses the roles of the appliances in the cluster: the passive appliance becomes the active node, and the formerly active appliance becomes the passive node.
