Go to SolutionConnectX-6 Dx firmware issues for R7725 servers
We have just purchased 17 of these servers, and what an absolute mishmash of firmware versions we have received.
Specifically, we have the following versions in ascending order 22.32.2004, 22.36.1010, 22.42.10.00 and 22.43.2026
Quite reasonably, given they are all going to be part of a cluster, I would like to get them all running the same firmware version. I have been bitten too many times with different firmware versions, causing issues.
The problem is that the latest version I can download is 22.42.10.00, which is older than the version on some of the cards. However, the ConnectX-6 Dx cards in my XE8545 servers have an even later version, 22.44.10.36, available for download and are, in fact, running that. That update won't apply to my R7725's (I have tried).
Can whoever is responsible at Dell sort this out ASAP?
I would also note that some of the servers have CLPD version 1.03, while others have 1.04, with no firmware option to download and bring them all into alignment. These servers have been out for several months now, so there is no excuse.
Finally, the "new" experience when looking to download updates is a steaming pile of Brontosaurus droppings. Whizzy, slow and cluttered is always worse than functional, fast and clear.

Did I answer your query? Please click on ‘Accept as Solution’. ‘Thumbs up’ the posts you like!@DELL-Charles R I can assure you that my servers only have the ConnectX-6 Dx cards in them (for crazy pricing reasons both an OCP card and a PCIe card because it was cheaper than just an OCP card, go figure).
As such a couple of my servers with a ConnectX-6 Dx card have firmware version 22.43.2026 as reported by the firmware inventory on the iDRAC and mlxconfig.
Consequently, I will repeat my entirely reasonable request for at least firmware version 22.43.2026 for the ConnectX-6 Dx cards on the R7725. Noting again that the ConnectX-6 Dx OCP cards in my XE8545 servers are running 22.44.10.36, which is even more recent.If the July server update only includes 22.42.1000, which I can download as an individual update anyway, as I mentioned in my original post, it is as useful as a chocolate teapot.

Hello,
I found ConnectX-6 DX v.22.44.10.36
I'm not sure it will work with the R7725 but you can try.

Did I answer your query? Please click on ‘Accept as Solution’. ‘Thumbs up’ the posts you like!None of that worked. It is incredibly frustrating that Dell ship a collection of supposedly identical brand new servers, some of which have more recent firmware than others and for which there are no downloads available to align them all.
Then again the drives up the front in our XE8545's still don't have a firmware you can apply to them on the machine. Guru level hacking to extract the firmware, from the download for different servers, trim the Dell header off and apply on my "drivinator" machine. Really what is Dell playing at these days with firmware. That's the last two lots of machines Dell have shipped us with firmware update issues on kit costing more than a million dollars. That's frankly rubbish customer service.
Time I think to engage pro support and vent my spleen.

@jabuzz Did you find a solution to this?
@pieman1 Yep, got the time to work through all the machines again, applying firmware updates and stepping through 22.40.1000 was enough to get everything sorted. So everything is now on the latest firmware and all aligned, as there are now firmware updates for the CPLD, FPGA, etc., to bring everything to the same level.
That is apart from the PSUs, where some of our 1500W Delta PSUs were on 8727 and some on AE31. However upgrading the 8727 ones to AE31 and they end up being AE27. If you try to upgrade those to BC31, they end up being BC27 instead. The ones on AE31 upgraded to BC31 without issue.
Oh boy, what a complete and total disaster area firmware has been on these machines.Dell-Martin S

To ease any concerns about cluster power balancing or erratic iDRAC failures, you can confirm compliance through the lifecycle logs:- Check the iDRAC Job Queue. If the update task for the
xx27supplies completed with aStatus: Successand aJID_SUCCESScode, the digital signature and payload were accepted fully. - If the power supplies were mismatched in a dangerous way, the iDRAC would trigger a
PST0185(PSU Redundancy Degraded) or a configuration error. If both units show "Online" and "Green" in your power topology, they are safely load-sharing.

@Dell-Martin S The issue is that the PSUs are at "unknown" firmware levels. Applying firmware version AE31 to a PSU with firmware level 8727 should not result in it ending up at firmware level AE27, which is a firmware level not listed for that model of PSU.
The only levels I can download are 8727, AE31 and BC31, so where the heck do AE27 and BC27 come from?
As such, it is another case of the firmware for these machines being completely foobar.

Are you managing these 17 nodes via Dell OpenManage Enterprise (OME), or are you managing the iDRACs individually/via API?

Might not be the same but I reckon it probably is.
We received a bunch of OCP cards which wouldn't update either. After some searching we had to use this firmware as despite other firmware saying compatible it obviously was too larger step for it to install the absolute latest properly.
