You can configure xHA with dedicated management enabled on both nodes, or disabled. xHA can also be configured with IPv4 only, or with IPv4 and IPv6.
xHA with dedicated management enabled requires the use of new IPv4 addresses for both the Management interface (eth2) and the Service interface (eth0). When creating an xHA pair with IPv4 and IPv6, you must also configure a new IPv6 address for the Service interface.
xHA with dedicated management disabled requires the use of a new IPv4 addresses for the eth0 interface. When creating an xHA pair with IPv4 and IPv6, you must also configure a new IPv6 address for the eth0 interface.
- For more information, refer to Updating or applying patches to servers in an xHA pair.
- You can't configure interface and network settings of DNS/DHCP Servers that are part of a functioning xHA pair. Configure interface and network settings before creating a high-availability pair.
- You can't configure interfaces if the DNS/DHCP Server is under Address Manager control. Remove the DNS/DHCP Server from Address Manager control to configure interfaces.
- You can't configure interfaces if network redundancy (bonding) is enabled. Disable redundancy from the Administration Console to configure interfaces. Disabling bonding will also remove the DNS/DHCP Server from Address Manager control.
