/proc/mdstat and cciss not available, how to know your disk is raid

Im issuing a cat /proc/mdstat, dmraid -r, and finding a cciss, to know if my server is software raid and hardware raid. But all of them are missing.

What is the other way to know, your disk are raid, your disks is sync, your disk are out of sync, your disk is failed, ASIDE LOOKING AT THEM physically.

My server is old IBM blade hs21, under linux suse 10.3
and the other one is linux suse 11.5
