Specifying partners in an asymmetric HA pair setup

You can use the interface name of the partner instead of the IP address to specify the partner interface when setting up an HA pair.

About this task

In this example, two storage systems, storage system1 and storage system2, are configured as shown in the following table:

Storage system

vFiler unit (associated IP address)

IPspace

Interface name

storage system1

vfiler0 (1.1.1.1)

default

e0

vFiler1 (2.1.1.1)

ips1

e1

vFiler2 (3.1.1.1)

ips2

e2

storage system2

vfiler0 (1.1.1.2)

default

e0

e4a

e4b

Steps

  1. Specify partner interfaces on storage system1 by creating a host-partner relationship using the following commands:
    ifconfig e0 1.1.1.1 netmask 255.255.255.0 partner e0
    ifconfig e1 2.1.1.1 netmask 255.255.255.0 partner e4a
    ifconfig e2 3.1.1.1 netmask 255.255.255.0 partner e4b
  2. Specify partner interfaces on storage system2 by completing the following steps:
    1. Create two IPspaces: ips1 and ips2.
    2. Assign interface e4a to ips1 and interface e4b to ips2.
    3. Create a host-partner relationship on storage system2 by entering the following commands:
      ifconfig e0 1.1.1.2 netmask 255.255.255.0 partner e0
      ifconfig e4a partner e1
      ifconfig e4b partner e2
