The UCS drives I have are firmware A005 since we keep them updated with HUU as recommended. The UCS-C22-M3 requires a 9240-8i for ESXi to be able to be installed. We are trying to find an actual use for it. The 9240-8i requires firmware A001 to be on my drives (Cisco part A03-D300GA2, which is Seagate ST300MM0006), according to the compatibility matrix.
Is there any way to downgrade the firmware to match (and fix the "unsupported" error in LSI WebBIOS), or does everyone just buy new drives?
You may want to check to confirm the LSI raid controller is running at least package version 20.13.1-0255.
This was available as of huu 3.01c for c22m3's
I could maybe see a scenario where your 9240 doesn't have the later firmware,,, and isn't sure what to do with the supported drive running a later firmware.
Do you get the Seagate drive firmware from the HUU update process?
Looking at the EOL statement for the C22M3, https://www.cisco.com/c/en/us/products/collateral/servers-unified-computing/ucs-c-series-rack-servers/eos-eol-notice-c51-733776.html

The only updates you would have seen for this server after 2016 are vulnerability/security updates.
Also noticed the 9240 raid controller is a linked component listed in the EOL statement at https://www.cisco.com/c/en/us/products/collateral/servers-unified-computing/ucs-c-series-rack-servers/eos-eol-notice-c51-733777.html, so would not expect to see firmware released after 2016 for it either.
I checked LSI/Broadcom's site for the 9240 and the last firmware update specifically for the 9240 was in 2015.
As the HDs are not specific to just that server or raid controller, you can see additional firmware updates come out for those (i.e. via C220/240 HUUs ).
I can see how you might get into your scenario where the HD update is later than the raid controller, making the controller think the drive isn't a supported model.
The HUU doesn't do HDD firmware downgrades, but you may be able to try using the Webios (contrl+h) utility, or storcli utility to push the older drive firmware. I don't have any docs on this process, as it's not the supported way for upgrading(downgrading) drive firmware.
Updating to the latest supported firmware is generally a recommend troubleshooting procedure.
However, I think you may have mixed and matched your firmware sources, which is where we ran into issues. Which specific HUU did you get the drive firmware from?
Don't really see any good options that doesn't include newer hardware.
