You have to mount the partitions on the second hd on your e-smith system. It would go something like this:
#first make a directory to mount the drive to
mkdir /mnt/rh7
#now mount the drive with this command, assuming your partition is the first one on the 2nd hd is the primary slave
mount -t ext2 /dev/hdb1 /mnt/rh7
good luck!
