I think this concern is primarily for *software* RAID arrays, especially
when you want to setup a software root-RAID. I have limited experience
with hardware RAID arrays, but I don't know why it would be a
problem. Linux (or any other OS for that matter) essentially "sees" the
hardware array as disk space and other than any special monitors to detect
disk failure, doesn't really concern itself with a failed drive. The
health of the array should normally be monitored by the hardware raid
card's BIOS.
Again, I don't claim to be an expert on hardware RAID and someone else may
point out the error of my ways, but I don't see why you'd have any
difficulty putting the whole mess on a hardware RAID array.
