Hi,

One of our customers has enabled network failover on 2nd level vifs for their cluster,

When trying to add a new vlan, they are getting error below

nbg2-fas13> vlan add fas13-2ndLvl01 316

vlan: Create failed. Negotiated failover is enabled on interface fas13-2ndLvl01.

nbg2-fas13> ifconfig -a

Do you think we could disable nfo, add new vlan, and then re-enable nfo ?

Thanks and regards

That should work..you could also set nfo on each vlan ifconfig itself instead.

Thanks Scott,

We shall give that a go alright so

We would need to get an outage to test new /etc/rc config if we went to enable on each vlan config

and this particular customer won't allow changes to /etc/rc with change request and tests after changes made

regards

Jack

Makes sense. I prefer customers that plan and schedule 🙂

Hi All,

I did some testing today, and unfortunately  it did not go too well, I was able to disable negotiated failover on my vif,

And then create the new vlans, but not re-enable it !

vlan: Create failed. Negotiated failover is enabled on interface vif1.

Any ideas ?

So with vlans it looks like nfo is per vlan ifconfig only. Unless ontap 8 and there is an ip on the base I tagged vif.

Cheers Scott,

Only saw this now, yeas, it looks like that alright,

I shall investigate further next oppertunity i get

thanks & regards

Each time, I have to ad VLAN on nfo interface, I do that.

I'm working on DoT 8.1 GA and NFO is set on the vif not per VLAN.

scottgelb

Nfo can be applied to any interface you ifconfig. If the base Ifgrp then it won't apply to a vlan on that Ifgrp unless the vlan ifconfig has nfo. The base ifgrp is a different logical interface than the vlan. Apply nfo to any/every interface you want failover to occur on. Then make sure the options is set to any_nic or all_nics if you want all interfaces with nfo to have to fail or just one for the failover to occur.

I'm interested in reading what NFO can do on a VLAN basis.

DoT can detect an issue on VLAN configuration like the loss of a VLAN into a trunk?

I put on the ifgrp because I know that on this particular interface, if something goes really wrong, I want to takeover.
