Downgrade ILOM / BIOS / RAID controller on X6-2, X5-2, X4-2, X3-2
I have a case where I think an ILOM-update incl. bios and raid controller update has degraded the performance of an X6-2 server. I want to go back to an earlier version of the BIOS and Raid controller. Is there a guide or a do's and don't for downgrading firmware on an Oracle server using fwupdate in Solaris 11?
