an MD device will only be applicable if you are using software raid.  you
need to also check whether you are using hardware raid (PERC 2/Si onboard
or a PERC2 or 3 PCI card) or just the onboard scsi bus for software raid.

if you can do a ctrl A i am assuming it is indeed a perc hardware container
so there is some problem at that level.

in the perc controller bios can you see all the individual drives ?  there are
some dell diagnostics on the dell installation cd i believe, though i am not
sure how much can be tested here - e.g if all the drives seem fine then it
is most bizarre.

in the controller itself there might be an option to "reconstruct" raid from
the existing drives.  at this point i'll defer to someone from dell to answer
this query who might be able to talk you through that process.

do you know what the cause of the failure was - i.e did it just stop working
at some point and was rebooted or what else happened ?
