# RHEL requires some extra work...
# To start, on RHEL, Amazon uses your device above, 'sdx', in the console, but at the hardware level creates a device named something like: /dev/xvdad

# Then you have to format and mount it.
#  mkfs.ext3 /dev/xvdad
#  echo "/dev/xvdad /mnt/sillyname ext3 noatime 0 0" >> /etc/fstab
