HPE ProLiant DL360 Gen10 SPP USB Boot

TLDR: Make sure the USB drive is USB 2.0 and under 32GB and the HP USB Key Utility must be used.

Had a bit of a game with this today, server not updated since 2017 so with a couple of versions of iLO to upgrade through thought it would be easier to put the SPP on a USB drive.

Downloaded the ISO (which took forever to find, thanks HP) and imaged with Rufus which didn’t work. Then found the HP USB Key Utility and tried another 2 USB 3.0 drives which also didn’t work. The server recognised the drive but when trying to boot it wasn’t having it.

One 32GB USB 2.0 drive later and it’s finally booted.

Error: “Cannot find vSphere HA master agent” After vCenter 8.0 Update 3e

After patching our vCenter this afternoon from 8.0 Update 3d to 3e I encountered the following errors:

Cannot find vSphere HA master agent

vSphere HA agent for this host has an error: The vSphere HA agent is not reachable from vCenter Server

Broadcom has a fairly helpful guide which basically involves turn HA off and back on again.

However it doesn’t mention to wait at least 5 minutes after switching HA off. The first time I did the switch off and back on it didn’t fix the issue but after switching off, waiting 5 and then switching back on the hosts remediated and elected themselves correctly.
