I am trying to revive an old IBM x3650 M2 server, but am running into trouble with IMM/IPMI related to the FW being almost as old as the server itself. Server is from 2010, firmware is from '09 (UEFI) and '11 (IMM/DSA) and is running ESXi.
I checked the official supportsite (that has no firmware at all for the server) and did my best Google-fu, but have not found any useable FW download. The problem I'm having (IMM changes "Failed in the backend") is "common" and others have resolved this same issue with a firmware update, so that's my focus.
There might be other ways to find/update FW that I haven't thought of, and any ideas are more than welcome.
