LDOMs and virtual networks?
Got a question on how to switch networks with LDOMs. Basically I took over after a co-worker moved on and ran into an issue where he has an ldom configured on the wrong network. Just to throw some more confusion in the mix the ldom will be connected to an admin network and then a network with zones running off the ldom.
I look at a ldm list-bindings and see this in the VSW section:
Code:

As I'm understanding it the primary-vsw1 is correct and will stay and the primary-vsw4 will need to change to the same vlan as ldom3 (primary-vsw7 or 8)
So here's where the confusion sets in, I saw the nxge0 entry and thought the ldom was assigned to that port, went back and unplugged the cable and I'm still able to ssh into the zones (yes saw a nxge0 link down message in /var/adm/messages) so is there some redundancy? I see a VID of 77 on 3 interfaces so if one fails will it go down another interface?
Is there a better command to tell me how the ldom vlan is configured?
Thanks |
