ESXupdate Error Code 15

I ran into this issue a couple weeks ago, and after two weeks of Dell and VMware troubleshooting, the issue still was not resolved. I discovered the resolution and wanted to share with everyone in case you come across this same issue.

Issue:
Two brand new Dell R740xd servers, both with an Intel x520 NIC adapter in one of the slots. I had installed the Dell custom ESXi 6.7 image, but noticed that the x520 NIC was visible in the iDRAC console but was not detected in ESXi. I then wiped the server and installed the Dell custom ESXi 6.5 U2 Build 10719125 image, again the x520 NIC was visible in the iDRAC but not detected in ESXi.

Resolution:
I found an article, sorry can’t remember where, that stated the x520 NIC adapter need the ixgbe 4.4.1 driver, which was not present in either of the Dell custom ESXi images I had tried. I installed the drivers and still the NIC did not show in ESXi in either server. I then did updates in Update Manager, which brought it up to build 13004031, which SOLVED the problem. So it was a combination of the 4.4.1 driver not present in the ESXi image and the build version. In conclusion the 6.7 ESXi image might have worked as well IF it had contained the correct ixgbe driver.

Download and Install the 6.0 ixgbe 4.4.1 NIC driver:

The link VMware provides for a 6.5 ixgbe 4.4.1 driver does not work, so use the 6.0 one above.
