It looks like hdb1, hdb2, and hdb3 are part of device mapper devices,
which probably explains why you can't mount them.  It looks like these
partitions have been claimed by the mdp device, which seems to be part
of the software RAID system, in which case you might have to mount
/dev/md devices or /dev/mapper/<something> devices.

If you have some sort of hardware RAID controller, it might also be
the type that requires the OS to handle the RAID, and most of these
are now handled by the device-mapper and md drivers as well.
