HP PC Hardware Diagnostics UEFI helps you diagnose and fix PC memory, disk, etc, problems on Startup. Learn how to use it, install it or disable it.

HP Print and Scan Doctor will then run a series of diagnostics and attempt to fix any issues it detects. This may include checking the printer’s status, network connections, driver problems, etc.

So, power host down, check memory, run HP diagnostics, pass, run HP SmartStart firmware up date, clean IML in iLO and reboot into vSphere.
