We've neglected to upgrade our PowerEdge R910's BIOS since we bought them 3-4 years ago, so we are currently running on 1.1.7 - for the past 2-3 days, I have trying to upgrade the BIOS to 2.10 (and below) but failing miserably.
I have updated the iDrac firmware to 1.98 (Build 08) and Lifecycle Controller Firmware to 1.6.0.73, when I go into LC Platform Update, select FTP, I get the available list and the only component which needs to be updated is the BIOS, everything else has successfully updated fine. When I select BIOS update, it starts to download the file and then apply it but an error mismatch notification is displayed and server reboots back into LC.
I have gone to downloads.dell.com site and downloaded previous BIOS updates ie R910010202C.exe, R910-020500C.exe and the latest R910-021000.exe, copied one of them onto a USB stick and tried to update the BIOS within LC Platform Update via USB - it reads the USB and then comes up with a Dell Non-Authorised message (which is what I was getting via the FTP update before updating iDrac & LC to a newer version).
We are running ESXi 5.5U2 on the units and I'm at loss now on how I can bring the BIOS update to date.
Any help/suggestions is much appreciated.
