Changing VLAN on AIX lpars in the same subnet
Hi Guys,
Our lpars is currently running on 2 different vlans (20, 30). Now we have a requirement that vlan 30 needs to be change to vlan 31 at the same subnet. I'm not sure on what is the best approach for this or what change is involve on the AIX side.
This is our setup.
Network switch - trunked (allowed vlan 20, 30)
note: vlan 20 is the previous default vlan before it was changed to "trunked" and added vlan 30.
VIO1 and VIO2 - SEA (ent4) with ent2 (PVID 1) and ent3 (PVID 88, VLAN ID 30) attached to it.
lpar 1 - ent0 (PVID 1)
lpar 2 - ent0 (PVID 30)
Scenario:
Network team needs to change vlan 30 to vlan 31.
Change to be made on AIX lpars:
1. on VIOS, Add a new virtual adapter on SEA with PVID 89, VLAN ID 31
2. on lpar 2, this is where I'm confused if I need to change anything or not. Do I need to change PVID 30 to 31? Or I can just DLPAR the current ent0 and add VLAN 31 there?
I'm also confused on how PVID works on AIX clients.
Any inputs will be very much appreciated.
Regards,
K
