what i would do is
reboot the system but with the kernel options init=/bin/bash (you can
edit a grub stanza at boot up time so no need to make it permanent)
then I would have a look at the system from the kernels perspective see
what drives are available hd's or sd's. work out the problem from there.
Then look at the raid device, I would try and assemble them (not
recreate them) and see what the problem is, have a look at dmesg and
syslog.
I would work it from there.
