vSphere HW and Tools Upgrade Anomalies

Jump to solution

I just did an upgrade on our virtual machines to hardware version 7 and the latest tools. I started getting errors that our DHCP scope was filling up. I checked it and it was handing out IP addresses to our vm servers. All of them have statically assigned IP addresses. I cleared all the records out of DHCP, but does anyone have any ides why this would happen? Does this create some hidden NIC or something? And will it continue happening?

Thanks,

Scott

Apparently the HW upgrade does actually replace the NIC - leaving the old one "sort of there" - see vmproteau's pdf

So I guess that could be related to where your dhcp leases were coming from - or maybe as some intermediate stage of the upgrade the dhcp leases were allocated before the static addresses replaced them?

In what order did you upgrade? (Correct should be VMware Tools first and then HW Version)

That's correct. It actually won't let you upgrade the harware until tools is upgraded.

Has any seen this at all? It seems like really odd behavior?

This is exactly what I was looking for. Thanks a lot. Now I get to remove ghost NICs from all our servers.
