Hi, I need some advice on how to successfully apply the latest firmware HUU to a Cisco UCS C220 server with Secure Boot enabled.
I'm trying to upgrade from 2.0.x to 3.0.4d. When I boot from the physical dvd or mount iso using vKVM, I get an error immediately after selecting the drive, stating "Secure Boot Violation. Invalid Signature Detected". I've also tried upgrading through IMC Supervisor but that produces a very generic error that is extremely difficult to troubleshoot.
I've seen some information in one of the configuration guides that suggests a signed version of the HUU media is needed, but I cannot find where to download this. Has anyone else faced this issue?
Many thanks for your help.
