VMware Hypervisor failed to boot after update C220M4 to latest BIOS

[doran_lum]

With the recent update of our vCenter, there were a lot of storage errors. I spoke to VMware support and they mention the physical hypervisor does not have the latest BIOS. Our VM boots from a USB thumbdrive.

After updating to the latest 3.0(4i), I encounter the error below.

How should I troubleshoot on this ?

I would try booting the same ESXi Installer ISO version that the server is running on, and see it detects your esxi installation partition.

Searching on those errors mostly comes up with ESXi patching related issues such as:

Do you get the option to revert your hypervisor (see https://kb.vmware.com/s/article/1033604 ) ?

Thanks,

Are you within the support matrix?

Your hypervisor may have had too old of drivers for the 3.x firmware code. Here's a good doc on the driver installation process:
