Configuring a partner interface in an HA pair

To prepare for a successful takeover in an HA configuration, you can map a network interface to an IP address or to another network interface on the partner node. During a takeover, the network interface on the surviving node assumes the identity of the partner interface.

Before you begin

When specifying the partner IP address, both the local network interface and the partner’s network interface must be attached to the same network segment or network switch.

About this task

Step

  1. Depending on the partner configuration that you want to specify, enter the following command:
    If you want specify a... Enter the following command...
    Partner IP address
    ifconfig interface_name partner address

    interface_name is the name of the network interface.

    address is the partner IP address.

    Partner interface name
    ifconfig interface_name partner partner_interface

    partner_interface is the name of the partner network interface.

Example: Specifying a partner IP address and partner interface name

Consider node1 and node2 are two storage systems in an HA configuration.

If the IP address of the interface e8 on node2 is 198.9.200.38, the following command allows the interface e1 of node1 to take over the IP address of node2 for the duration of the takeover:
node1> ifconfig e1 partner 198.9.200.38
Instead of specifying the IP address, you can also specify the partner interface name. The following command allows the interface e1 of node1 to assume the identity of e8 of node2 for the duration of the takeover:
node1> ifconfig e1 partner e8
