How can I change VIF trunk mode

SHANEMURRAY10 · ‎2011-07-20

Hi

I am using NetApp 7.3 on a clustered solution.

I need to change the trunk mode of 2 VIF's from "multilple" to "single" mode.

I simply browsed to the VIF and changed this but it doesnt seem to apply. What is the correct procedure to do this? Do I need to recreate the VIF?

Many thanks in advance

Hi,

Have you try to make down and up the VIF ?

By which mean, you change this mode ? System Manager ? CLI ? FilerView ?

Or last chance, if you are locked, reboot ... or in CFO, taker over giveback ...

In CLI, Could you give us the result of :

Vif status

and

rdfile /etc/rc

still need to change the switch config too.

And you can edit the rc file to:

hostname NetApp1

vif create single vif1 e0b e0a

vif create single iscsi e0c e0d

ifconfig vif1 `hostname`-vif1 mediatype auto netmask 255.255.255.0 partner vif1

ifconfig iscsi `hostname`-iscsi netmask 255.255.255.0 mediatype auto mtusize 1500 partner 172.16.2.105

route add default 10.50.1.1 1

routed on

options dns.domainname test.local

options dns.enable on

options nis.enable off

savecore

And then issue this command:

netapp1> source /etc/rc

If you do not change the switch config (port trunking), the network connectivity will be interrupted!

thanks!

I will give that a try and let you know how I get on!

You also need to change the switch config of the ports (or repatch the cables to other ports that are not "multi" trunked)...

Then the change to single should be working (up and down should be automagicaly)
