I recently purchased the MFS2600KI server blades. I was running on firmware 10.9 on my MFSYS25V2. After installing the MFS2600KI in the MFSYS25V2 it was not detected. I assumed since the MFS2600KI is relatively new the MFSYS25V2 needed a firmware update.
In the natural progression of things I ended up on the Intel Downloads page for the MFSYS25V2 page. I selected Independent OS's and BIOS.
The following two popped up:https://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=21139&ProdId=3331&lang=eng Firmware update for Intel® Modular Server System MFSYS25V2
andhttps://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=21637&ProdId=3331&lang=eng Firmware update for Intel® Modular Server System MFSYS25V2 only
This is where I ran into the problem because I selected the one with the higher number (11.6) thinking it was more current.
Now I found out that 11.6 does NOT support the MFS2600K but the 10.16 does. The dilemma I am in is that I cannot downgrade to the 10.16 firmware.
Is there a procedure that can be used to downgrade or restore the older firmware?
10.16 is actually a later version, but without Virtualization Manager. It's supported to upgrade from 11.6 to 10.16. For more details, please refer to the release note.
