we are using VSphere 4.1.1 with esxi i a HA Cluster with one big dvSwitch for all the VMs.
Now i want to remove (only from one of my esxi's) a physical nic that is located within a dvswitch. (On the host under the Configuration - Network Tab)
What happens in this case? Lose the vms their network connection for a short time? Or will be the nic (vmnic5) removed on all esxi's globally??
Thx in advance
At the host's configuration->network tab, DV switch configuration is done on a per host basis, it won't affect global settings. One can add/remove vmknic , uplink on a per host basis at this place.
The only thing to watch out for is that you NIC sequencing can change of you change the physical hardware - so make sure that once you bring the host back online your mappings are still ok and all networks function as expected before adding VMs back to the host.
