On failover, the interface will move to the partner defined on the ifconfig line. As long as the vif keeps the same name, you can edit the vif config in the rc on the orginal filer and the failback will work just fine.
Assuming the partner filer has 'vif_rsec' in the ifconfig partner line, this should work:
Before: ifgrp create lacp vif_r0 e0a e0b ifgrp create lacp vif_r1 e0c e0d ifgrp create lacp vif_rsec vif_r0 vif_r1
After: ifgrp create lacp vif_rsec e0a e0b e0c e0d
Change interface names and type as needed.
If you are using vif_r0 and vif_r1 on the partner, you'll have to move the interfaces to vif_r0 as you discussed.

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,
