Thanks to everyone that responded. We had a couple of problems that we 
eventually corrected. Our main problem was caused by the CICS Transaction 
Gateway (ctg) not returning control from the Linux INIT script. I will 
pass along the steps we took for those newbies like myself, who might find 
themselves in a similar situation.

We run Linux in a native LPAR. We use the HMC as the Linux console. Since 
ctg did not relinquish control, the init script stopped. We had no ability 
to logon or enter any Linux commands. Out goal was to disable the 
automatic startup of CTG. Since startups are in /etc/init.d/ which is part 
of the root file system, we identify volser LNX001 at UCB address 2534 as 
the necessary DASD containing the root file system. The Linux Recovery 
System was successfully booted from the installation CD and the following 
steps were taken to disable the automatic startup of CTG.

Load the appropriate DASD driver
modprobe dasd_mod DASD=2534 dasd_disciplines=dasd_eckd_mod

Define UCB 2534 to Linux
echo "add device range=2534" >> /proc/dasd/devices

Mount the root file system on /mnt
mount /dev/dasda1 /mnt

Run subsequent Linux commands with /mnt as the root
chroot /mnt

Disable automatic startup of CICS Transaction Server
chkconfig ctg off

Shutdown the Linux Recovery System.
shutdown ?h now

Reboot the Linux LPAR as normal.
