I tried to install both firmwares on one of the nodes, but they're not compatible. Most of our disks are HGST HUH721010AL5200 10TB SAS disks. On 12/05/2025 10:51, Frédéric Nass wrote:
Hi Janek,
I just checked and we upgraded both HDD and SSD firmwares to those versions released last month.
HDD firmware (DELL/Seagate 'ST16000NM006J'): https://www.dell.com/support/home/en-us/drivers/driversdetails?driverid=xf65r&lwp=rt NVMe firmware (DELL/Kioxia 'Dell Ent NVMe CM7 U.2 RI 1.92TB'): https://www.dell.com/support/home/en-us/drivers/DriversDetails?driverID=VH1YP&lwp=rt
What models are your drives?
Regards, Frédéric.

Hi all,
Kernel is 6.8.0 (Ubuntu). The thermal settings on iDrac are already quite high and we have an overall good cooling system, so that shouldn't cause any issues. Our cold aisle is around 20˚C.
@Frédéric Do you have a link to the HDD firmware? I installed everything that's available in the Dell catalogue. Also, I don't know whether CPU usage is high during these lockups, since I cannot observe the host state when it happens. It's like the entire node goes down until either it recovers on its own or I do a hardreset.

There are separate thermal, overall performance, and fan states in iDRAC. I’ve found that I often have to bump up the default “fan offset” for more cooling.

Hi Janek,
We just had a very similar issue with recent hardware (DELL R760xd) going nuts (100% CPU load) for like 10 to 20 minutes and OSDs being reported 'down' as not responding in time.
Switching the CPU profile to HPC (High Performance Computing) and the thermal settings to Maximum Performance (or is it Optimized?) in BIOS, and upgrading HDD firmware to the latest one taht was only available from DELL's website (not yet in OpenManage catalog) fixed it.
Maybe you can give it a try.
Regards, Frédéric.

Hi, it's happening again. I haven't fully upgraded the firmware on all hosts yet, but at least on all MDS. I managed to finish the Ceph upgrade, but now I'm randomly getting the soft lockups again (mostly, but not only) on the MDS hosts.
Anything else I could check for?

Yes, we have a mirror of the Dell Firmware catalogue, so the servers can check what they need. There are three updates in total: BIOS, NIC, and Lifecycle Controller.
I hope the BIOS update fixes this.
