Example 7-4 shows where the VIF is configured in setup. Configure a multimode VIF, which is
the default, by using all four Ethernet ports of the N series controller.
Example 7-4 Configuring a multimode VIF
Do you want to configure virtual network interfaces? [n]: y
Number of virtual interfaces to configure? [0] 1
Name of virtual interface #1 []: vif1
Is vif1 a single [s], multi [m] or a lacp [l] virtual interface? [m] m
Is vif1 to use IP based [i], MAC based [m], Round-robin based [r] or Port based [p] load
balancing? [i] i
Number of links for vif1? [0] 4
Name of link #1 for vif1 []: e0a
Name of link #2 for vif1 []: e0b
Name of link #3 for vif1 []: e0c
Name of link #4 for vif1 []: e0d
Please enter the IP address for Network Interface vif1 []: 9.11.218.173
Please enter the netmask for Network Interface vif1 [255.0.0.0]:255.0.0.0
The Interface Groups can also be configured by using Data ONTAP FilerView or IBM System
Manager for IBM N series.
7.3.5 Configuring interfaces for takeover
During the setup process, you can assign an IP address to a network interface and assign a
partner IP address that the interface takes over if a failover occurs. In that case, the IP
addresses from the controller that is taken over can be accessed, even if it is down for
maintenance.
LAN interfaces can be configured in the following ways:
򐂰 Shared interfaces
򐂰 Dedicated interfaces
򐂰 Standby interfaces
Configuring shared interfaces with setup
A shared network interface for the local controller and the partner. If the partner fails, the
network interface assumes the identity of a network interface on the partner. However, it
works on behalf of the live controller and the partner. A network interface performs this role if
it has a local IP address and a partner IP address. You can assign these addresses by using
the partner option of the ifconfig command.
Example 7-5 shows how to configure the shared interfaces. The IP addresses of the
controller that is taken over is accessible on the local controller port e0b.
Example 7-5 Configuring shared interfaces with setup
Please enter the IP address for Network Interface e0b []: 9.11.218.160
Please enter the netmask for Network Interface e0b [255.0.0.0]:255.0.0.0
Should interface e0b take over a partner IP address during failover? [n]: y
Please enter the IPv4 address or interface name to be taken over by e0b []: e0b
After finishing the setup, the system prompts you to reboot to make the new settings effective.
Attention: If the partner is a VIF, you must use the VIF interface name.
