How to migrate an interface gruop nondisruptive from 1GbE to 10GbE ?

[ROUSSEAU_SFR]

Hi,

I want to migrate an interface group (nas330fct) from 1GbE to 10GbE.

e3a, e3b, e4a, e4b are 1GbE ports:

IFGRP	Interfaces
nas330fct	e3a, e3b, e4a, e4b

10GbE ports are e1a & e1b. IFGRP nas330fct should be the same (it have many vlan configured, so many IPs). Only interfaces need to be change from 1GbE to 10GbE.

I want to do this but it's disruptive:

ifconfig nas330fct down

ifgrp delete nas330fct e3a e3b e4a e4b

ifgrp add nas330fct e1a e1b

ifconfig nas330fct up

Do you have an idea to do a non disruptive operation ?

I think you can make the desired changes in the RC file-->Perform a takeover (Non Disruptive) -> Perform a giveback so that the new configurations can be re-read and all the vfilers/vlans's come alive on the new 10 GB NIC's

Ok so the process is:

1) From Netapp1: takeover of netapp2

2) Edit /etc/rc of netapp2:

Add:   ifgrp create lacp nas330fct -b ip e1a e1b

Remove: ifgrp create lacp nas330fct -b ip e3a, e3b, e4a, e4b

3) Giveback of netapp2

4) Repeat steps 1 to 3 with takeover of netapp1

Are you ok with this ?

Yes, this should work. But I would first test LACP on e1a and e1b just to make sure it's configured properly on the switch. Create a new ifgrp, assign a temporary ip, and test...

Yes this should work - in the RC file when you change the identity of the VIF from 4 ports to a 2 port one,basically nothing changes provided the data gets routed through the same VLAN.I am sure you are retaining the name of the VIF  as well.

Ensure that the new ports are plugged into the same VLAN and this VLAN is part of the same IPSPACE which was being used by the older 4 ports.

I dont anticipate any more problem.

As usual before performing the giveback perform a netdiag on individual network ports to ensure these are up and running.

Also makes sense to get the LACP tested by creating a temp IFGRP and an IP.
