All,

I am needing to re-order some of the virtual interfaces on an HA pair of 3170s running OnTap 7.3.7. The current configuration has:

2 x 1 Gbe interfaces in an LACP 'vif_r0'

2 x 1 Gbe interfaces in an LACP 'vif_r1'

1 second-level vif, vif_rsec, comprised of vif_r0 and vif_r1.

What I want to (eventually) get to is:

4 x 1 Gbe interfaces in an LACP vif_r0

And I don't want to take a downtime to do it. Unfortunately, with an HA pair, this isn't going to be possible (I don't think…).Once a failover and configuration change is made, the takeover partner doesn't have a "correct" interface to give back to, since it's "partner" interface name has changed. So what I'm proposing is:

Leave the second-level vif alone.

Remove the physical interfaces from vif_r1 and put them in vif_r0.

The question I have is: can I fully de-populate a vif of physical interfaces? Will it stick on the last one? I don't have anywhere to test this, so I'm hoping someone with some spare capacity can either test it and let me know if it will work.

Thanks in advance,
