R815 Error code 2900:0221 CPU voltage sensor
One of our R815 servers (fitted with quad AMD 6380 Opteron CPUs) halted and powered off during the night last week and on arrival in the server room, I noticed the LCD display had turned orange with a warning about a CPU voltage regulator being out of limits. After disconnecting the AC power cords, waiting a few seconds and reconnecting I powered the server back on again and the LCD message cleared and the server booted normally.
So I ran the UEFI hardware diagnostics and it came up with one error:
Test Results: fail
Device : IPMI
test : IPMI System_Event_Log_Check
Error Code 2900:0221
Msg: IPMI - Nov 04 18:08:34 2015: processor:: Voltage sensor (1.2V VDDR)
state asserted "CPU1"
Is this something to be worried about since the server has been running at full load on all 64 CPU cores for 5 days without any problems? Or does the error message actually refer to the IPMI/BMC processor CPU and not one of the Opteron CPUs?

Thanks for the prompt reply - I'll update the BIOS and iDRAC firmware as soon as I can schedule some downtime on the server.
Thanks & regards,
Andy

Just thought I'd mention that I cleared the hardware log through iDRAC yesterday afternoon and about 30 minutes later, the system spontaneously rebooted itself and the LCD display turned amber with the CPU 1.2 V VDDR voltage regulator error message appearing again. The system seems to be running fine so I will do the iDRAC & firmware updates as soon as I can.
