I almost stopped reading at "BIOS from 2007".

You should definitely upgrade the BIOS before barging in and saying
you've got a problem ;)

Was the drive handled by mpt too, or by mps ?

Let's see you update the firmware and tell us ;)

Usually, this is done using dell's ISO image.

You can either do that directly in front of the server, or remotely with
dell's DRAC and by using virtual media.

Keep in mind that virtual media might or might not be supported by your
DRAC firmware version.

If you can't use the virtual media, you may also boot dell's ISO via PXE.
