I believe that the 'RAID' setup is actually underneath
the /dev/mapper/VolGroup00-LogVol00 device. That is to say that part of
your RAID1 is handed up to LVM for your root filesystem. If you look at
how LVM is managing your disks(system-config-lvm) you will see
that /dev/mapper/isw_cfaabdceig is chopped up into the /boot slice and
another chunk that is used by LVM.
