If you do it with ifconfig, you will have to manually edit your /etc/rc and /etc/hosts files to make the settings permanent. Other options are to run setup or use FilerView to create it. These should both update all necessary files for you.

Either way you have to take the existing link down and bring up the new one, so there will be service interruption on that network.

Guys,

I've got to convert some filers from single links to VIFs to my cisco switches. I know I can do this with some edit to the rc file and a reboot.

Can I do it with the system up and with minimal disruption to NFS traffic? Or should I just look for some downtime and reboot?

Basically, I've got a single link on e11a now. I'd like to vif e11a and e11d. So, from the console could I do:

ifconfig e11a down vif create multi v1 -b ip e11a e11d ifconfig v1 <hostname>

And be done with it? I assume I might have to make some changes on the Cisco side as well, but I'd like to minimize my outage if possible.

When I do this, I check and double check my command and make sure it is all one line... something like this:

(remember, this is one continuous line) route -f ; ifconfig e11a down ; vif create lacp vif0 -b ip e11a e11b ; ifconfig vif0 192.168.1.10 netmask 255.255.255.0 up ; route add default 192.168.1.254 1

Notes: If your switch and ONTAP (7.2.1 and higher, I think) supports it, use LACP. It has much better and faster fail over capabilities. Otherwise, try multi mode. Make sure to use the "up" at the end of the ifconfig line. I also think, when using vifs, mediatype is automatically set to auto and flowcontrol is set to full.
