Re: C240-M5SX - UCSC-SAS-M5HD getting errant over temperature messages

Elliot Dierksen · ‎11-09-2023

I am in the process of migrating my lab from M4 to M5 servers, and I have hit a snag. The problem is with my main NAS which is running TrueNAS 13.0. As part of the upgrade I ordered Western Digital 2TB WD Red SA500 NAS drives to replace the SATA HDD's in the old unit. I installed 2 of the brand new drives and after a few moments the fans go to full speed and the HBA shows those 2 drives as over temperature. It seems awfully unlikely that I got 2 DOA drives. I was able to create a ZFS pool on them, so the OS thinks they are performing correctly. BIOS version: C240M5.4.3.2a.0.0613231011, CIMC version: 4.2(3h).

Here are all the particulars.

This gets even stranger. Here is what the CIMC is reporting.

Since there are no flames shooting out of my server, I feel pretty confident that the drives aren't actually operating at 1 million degrees. I saw this article on Reddit talking about this a year ago.

https://www.reddit.com/r/homelab/comments/xru0ct/cisco_ucsc240m5_reading_smart_temp_incorrectly/

I suppose I could maybe understand this if I were using SSD's from Joe's used auto parts and disk drives, but these are WD ones intended for use in a NAS. The Reddit poster was using Seagate IronWolf , so that was also a quality drive. What the heck?

Kirk J · ‎11-13-2023

The CIMCs are designed for and optimized for gear on the Server's spec sheet. The CIMC's capability catalog has profiles for the 'approved' gear from the spec sheet, and knows what the thermal/cooling requirements are.

Any time you get gear that is not Cisco specific or has customized Cisco firmware, you have the possibility of mismatched polling values or the way the field values are processed.. My guess is that the CIMC is reading some other smart info field other than the actual temp one, or the non-cisco drive isn't presenting the temp field in the way the Cisco PID'd drives would.

If your installed OS supports smartctl, I'd be tempted to run some smartctl commands against those drives and see if you get any matches for the "1769504" value, and see what field that really is.

Selective Self-tests/Logging not supported

I don't see anything in there that matches the 1769504 number.

Steven Tardy · ‎11-15-2023

I saw this thread the other day and sent a link to someone in UCS engineering.

1769504 decimal is 0x1B0020 hex.
0x1B hex is 27 decimal.
0x20 hex is 32 decimal.

Don't know for certain, but seems these values are getting read incorrectly.

Typically I would say open a TAC case and have TAC open a CDET to get this resolved, but if you are not using "Cisco certified" drives, then I'm pretty sure UCS engineering will consider this an "unsupported" use case and never fix the CDET nor underlying issue.

May be worth a TAC case just so the CDET can get created and investigated to verify the issue and documented for others.

Elliot Dierksen · ‎11-15-2023

Thanks, I hadn't thought of the decimal to hex conversion. This is my home lab, so TAC isn't really an option. I suspect you are correct about the response being "unsupported" even if I did open a TAC case. I am starting down the road of using an LSI 9300 internal PCI card for those drives, but that requires me to replace the internal SAS cables. This is proving to be a harder upgrade than I was expecting. Sigh....
