"No Network Adapter" Error installing/upgrading ESXi 5.1 on HP BL460c G7

Yesterday I had to update a bunch of HP BL460c G7 servers to the latest ESXi 5.1 Update 1. The first thing I did was download the HP customized ESXi 5.1U1 ISO which can be found at the HP website. After loading up the ISO and booting from it, the ESXi 5.1 installer would load but would always be stuck with the following errors:

  • When installing/upgrading from the HP ESXi 5.1U1 ISO, a "no network adapter" error appears
  • When upgrading using VMware Update Manager, the task is stuck at 22% and the console screen shows an error that it couldn't find the network adapter with a specific MAC address followed by "appending output to nohup.out"

A quick google search returns issues where earlier versions of the HP ESXi ISO did not contain the required Emulex drivers. This did not solve the issue as these missing drivers were added to the version I downloaded.

After a bit more troubleshooting, I stumbled upon the solution. In order to resolve the "no network adapter" issue, you must update the firmware of the Emulex 10GbE CNA adapters. This can be found under the HP drivers site labelled as "OFFLINE Firmware image (.iso) for HP Emulex 10GbE Converged Network Adapters and 10GbE Network Adapters".
