How do I Determine why the Server Freezes After a Patch or Update?

Server requires a reboot/reset when it tries to reboot during a Cluster Aware Update. The server showing it's powered off or it's powered on, but there is no video signal in the remote Keyboard-Mouse-Video (KVM).

In order to determine the scope of the issue, it's necessary to revise the BIOS version and the Sysinfo log to discard any hardware failure.
