HP ML350p G8 - Fan Solution Not Sufficient - ALL fans failing?

High-Performance Computing Workstations & Servers
1

Hi everyone! First time poster, long time watcher :smiling_face:

Does anyone have any experience with older HP Enterprise Servers at all? I’ve been using an old ML350P as a plex server for a while, and it has been… ‘sufficient’.

I’ve been planning to upgrade the CPUs and do some other tweaks, and finally got around to spending some time on the machine. I went to all of the trouble of upgrading the CPU’s, only to realised BEFORE i do this, i have to run an update ISO prior to doing this. I admitted defeat, and replaced the older CPU’s in the server, to begin the process of properly upgrading the CPU’s, the way HP wants… :face_exhaling:

On restarting the Server, it posted with RAM an CPU, then proceeded with:

1611 -Fan 1 Missing
1611 -Fan 2 Missing
1611 -Fan 3 Missing
1611 -Fan 4 Missing
Fan Solution Not Sufficient
Critical Failure Detected - System Shutting down in 5 Seconds!

Now, on a bit of research (not that it was required, really…) obviously the error is pointing out that the iLO (Intelligent Lights Out , HP’s IPMI) hasn’t detected any of the 4 fans, and has shut down to stop overheating.

Many have posted this, but usually only pertaining to having 1 fan not being detected.

My case, ALL fans are not detected. The fans are, however, On, spinning, and the 4 fan lights on the MB are all lit up with a GREEN LED.

I’ve tried cleaning the contacts, swapping fans, even resetting the NVRAM… to no avail.

Does anyone know of what is happening? Have i missed something? Should i roll back the BIOS? is there anything else i can do, other than buy a replacement montherboard?

It just seems odd that all of a sudden ALL fans aren’t recognised, when before they were all working fine.

Appreciate any help here guys… thanks in advance!

When my ML350p Gen 8 does stupid things on boot like that, a hard reset usually fixes it. Power off system, yank power cords, press power button to drain the capacitors.

Hmmm… haven’t done EXACTLY that, but i’ve literally pulled out both power supplies, and removed the BIOS battery…
Will give your suggestion a go, never thought of pressing the power to drain the capacitors tho!

Might actually do a complete BIOS & iLO clear, start from scratch…

:sweat:

Will let you know how i go!

I would suggest reflashing ILO and BIOS completly w/o preservance of any settings. A lot of NVRAM is going bad in gen9 lately, maybe its just a fallen bit in your firmware.

I mean, I dont know how that could happen in Gen8, but its a free solution.

Yeah, i think i might actually do that…! Thank you… will post back after i’ve tried that out :slight_smile:
Have also been hitting up HP directly with this issue… fingers crossed i can find and fix the issue, esp if it’s to do with ageing hardware, so anyone will be able to resolve later…

So… sigh i decided to clear the CMOS by removing the cmos battery.
This appears to have worked, as the date & time has been reset.
HOWEVER, i now can no longer log into iLO. What’s worse, is that i can’t get into the BIOS to reset/change the iLO password, because of this fan issue…

Did i just Brick my server? :scream:

Long shot but try it with a single cpu and maybe only fans 2-4 populated
