DL380e with Critical Temperature Threshold Exceeded

My DL380e server has just started rebooting and giving the following errors every few hours. See below. The room is not overly hot (27C) and the server is not under much load. 

A few days ago some changes which did not cause the problems, but may be related.  It was working fine for a week with 6 drives in the array, and the problem occured when a seventh disk inwas added into the array and the array expanded. 

- replaced the last disk in the array with a HGST 900GB 2.5 SAS drive and expanded the 7 disk array to most capacity on the disks. All the disks are the same HGST SAS drives (NETAPP X423_HCOBE900A10)

- moved the boot partition to a different logical drive and re-installed the OS (Ubuntu) 

- fitted a small 12v fan to the p420 to reduce the noise. This is being powered from the molex cable intended for the rear LFF cage

What could be the cause of the critical temperature error and reboot?

When I use the hpasmcli utility I see something strange is the problematic sensors. It is problematic as there is NO WAY any part of the server is at 18C, and sometimes sensor #45 reads 1C!

Re: DL380e with Critical Temperature Threshold Exceeded

Hi,

The Issue pointing to - Temperature Sensor 46, 47 - Location Storage , which could be the Storage Sub system( HDD's , Controller)

We could Suggest you to update the Controller Firmware , however now that you are using Non-HPE HDD's and their Firmware is not been tested with the particular server.

So non HPE drive is installed which has a non HPE firmware and if there is a conflict that the controller is unable to communicate with the drive firmware then there is a possibility of occurance of such issues.

and the Server ( Ilo ) is unable to read the temp of the non hpe drive.

Suggestions :
1. You can still try and update the below Firmware and check.
> BIOS
> Ilo
> Controller Firmware.

2. Please use HPE recommended HDD's:

Re: DL380e with Critical Temperature Threshold Exceeded

Thank you for the reply It did not help. There is nothing wrong with the net_app disks, they were not the trigger for the overheating errors. 

It was the small 12v fan. When this was removed from the power supply the fault vanished. 

Very strange. But... the fan is now being powered by an external 12v supply.
