So I have 2 HP ML150g6's in a ESXi cluster.
Node 2 died on me today, went to login via vSphere client and did not respond and had just powered up a bit before so check server and red light flashing. Rebooted and I get a beep code. Beep pause beep beep. Not really a long and 2 short but a beep and pause then 2 beeps close to each other. I had used the server a week before and upgraded RAM but worked fine then and I seen it boot up though the KVM so was running and booted but died at some point.
I swapped all RAM and tested each stick, RAM is good. I also tested slots and they are good. (since I have had both motherboards replaced due to not being able to accepts fully populated RAM slots on each processor).
Pulled all cards = no change
Looked for something on beep codes but all says long and short and not sure what they are I am getting exactly.
I can swap all parts with my other but not much else to swap, both boot from ESXi on a USB stick and have not local disks.
Any ideas would be helpful while I think about and research on my own as well! Unfortunatly this is my test lab and contracts of course have now expired.
This node has been finicky though, regardless of BIOS setting always wants to power up when it seem power at the PS and BIOS says not to.
I updated BIOS's for fans running at full tilt but will see if there is anymore updates.
Regards
