I have a bad NIC in one of my slots on an ESX 3.0.2 server. Id like to remove the NIC and replace it with a new one. Before I remove the NIC id like to know if there are any commands I need to run to 'unregister" the NIC and then what commands I woiuld need to run to "register" the new NIC.
Are you talking about a hot-plug NIC replacement? I think the safest way would be to shutdown the ESX and then replace the faulty NIC.
However, if you are using VirtualCenter, remove the NIC from the vSwitch and after hardware replacement add the new NIC to the vSwitch.
"esxcfg-vswitch" is the commandline alternative....
In this case I would remove the pNICs from the associated vSwitches, replace the NIC and (re-)add the pNIC to the vSwitches.
I'm pretty sure that this really isn't required but to be safe...
The system will be able to be shutdown completely. no hot-swap needed. I just wanted to make sure that once I pull out the bad nic and replace it with the new one, VMware wouldnt go bonkers looking for the old one because it would have been still "registered". The bad NIC is not even being used yet. i was going to start using it and then realized it had a problem. It has not even been associated to any Vswitch's yet either.
So it sounds like its easier than i thought.
shutdown ESX server, pull out old nic, put new nic in, turn box back on and all should be fine.
