When you use Multilink Ethernet on NetApp Filer(7-Mode), it is necessary to create a multi-type virtual interface from multiple interfaces by executing the following command on NetApp Filer(7-Mode);
vif create multi <virtual interface name> -b [rr|mac|ip] <interface1>, <interface2>, …
The virtual interface name is specified as vif0, vif1, vif2, and so on.
The value -b indicates load balancing. rr indicates round-robin distribution mode, mac indicates a MAC address, and ip indicates an IP address. Specify proper values according to the environment.
Example
vif creates multi vif0 -b ip e0,e1
The virtual interface is created with the above command. If NetApp Filer(7-Mode) is restarted, the virtual interface will be lost. Using the following steps, it is necessary to set /etc/rc that a virtual interface is automatically created during NetApp Filer(7-Mode) restart:
Mount /vol/vol0 on the NetApp Filer(7-Mode) management server.
Add the "vif create single" command that is used to create a virtual interface above the ifconfig line. The ifconfig sets up an actual interface in /etc/rc of NAS. Then, give a commentary # to the ifconfig, and add a new ifconfig line for the virtual interface.
Example
vif create multi vif0 -b ip e0,e1 #ifconfig e0 192.168.0.1 mediatype auto #ifconfig e1 192.168.0.2 mediatype auto ifconfig vif0 192.168.0.1 mediatype auto
