UCS C220 M3 Spontaneous shutdowns without errors nor warning

Fallstop
Level 1
Level 1

Hello,

I have an old Cisco UCS C220 M3 server which was stable for a couple weeks and has become increasingly unstable, to the point it no longer survives 10 minutes booted into an OS. There are no patterns to diagnose, just a very sudden power off that happens at no particular point, even during post, and a suspicious lack of errors. The status shows as fully healthy with everything listed, and absolutely nothing logged except for one "normal" message being spammed in the system event log. This is pretty concerning because CIMC should log something on shutdown no matter what.

 

"normal" message being spammed: "MAIN_POWER_PRS: Presence sensor, Device Removed / Device Absent was asserted"

Here is the idea of the spam quantity:

Bios and CIMC are updated to the latest 3.x, other devices are also updated to there respective versions.

 

BTW, I'm attempting to run such an old system because I picked up this server + part server for 200USD.

 

Thanks in advanced.
