ESXi Upgrade Failure

Upgrading one of my ESXi hosts in my lab failed on me, sure enough I figured this might happened and put a head on my usually headless server. This means I plugged in a monitor. at the screen I was this:

well that sucks, googling I found this thread from VMware.

looking closer at the boot error before this it stated:

system does not have secure boot enabled. This being an old mini desktop from the mid 2000’s it had uEFI but did not have the “feature” of secure boot. Clearly an after thought of the time. Now the odd part is when I hit the boot menu key “f12” in my case, I had the “legacy” BIOS style, list as P0: Hard Disk and EFI: Hard Disk. When I picked P0 one it booted just fine. So I figured just a simple boor order fix adjust some settings much like the thread (disable EFI boot and stick with legacy). I couldn’t see a way in my EFI/BIOS options to disable the alternative boot types, so I put the legacy type at the top of the list and the EFI one at the bottom, yet every time I booted it would boot the EFI one. When I check the vCentre system it wouldn’t remediate aka update to the new version, so I had to click remediate, run downstairs, and ensure I was there to pick the Legacy Disk boot, even after setting the boot order in the BIOS it wouldn’t stick to legacy and this was the only way I could get the upgrade to succeed.

Oh yeah.. this happened to me to, while I was trying to migrate some servers, I wanted to move some VM’s vNic into different VMPGs so I decided to rename the one they were currently using. I created the new VMPG in the alternative vSwitch, and i was a bit stumped to see them already there. I had presumed that once I renamed the VMPG it would reflect as the new name on the VM settings and still be on that old vSwitch (in secret it is). When I went to delete the vSwitch it told me error failed to delete “a specified parameter is not correct”. Googling I found this 10 year old blog that still relevant in ESXi 6.5.

Had to simply edit the VMs vNics and change them back. Dang Computers…
