Virtual Machines loose Network after ESXi 5.0 Upgrade

Hello

We have upgraded vcenter from version 4.1 to 5.0 without any issues

After upgrading the first of 11 ESXi hosts we have a problem with network connectivity.

Everything has been configured as before but one of the network adaptors is showing as on "stand by"

When i try to migrate a live virtual machine to the upgraded Host, the migration works fine but the VM instantly looses network connectivity.

Any idea what i am missing?

THanks

1. Are the Servers on the HCL?
2. Are the network cards on the HCL?
3. Have you checked you do not need updated drivers from VMware ?

go to configuration - > netowrking -> and then from "vswitch 0" the properties.

Look in the lower right bottom if both adapaters are standing on active.
If not edit the vswitch go then to the nic teaming tab and move the standby adapter to the active group and press ok.

This should fix it.

THanks, thats what I was missing!

However, even though both adaptors now show as active, if i migrate a VM to the upgraded host it still looses network connectivity

Any ideas?

The Host is on the HCL, as is the network card, but im not sure how to check for updated drivers

check your vlan id's
one has id 1 and the other server has no id

HCL - Hardware Compatibility List

Go to the VMware Site, and Check the additional drivers.

How many portgroups are on the vSwitch?

Make sure Network Labels are COMMON between Hosts.
