Chapter 2. Installing Red Hat Enterprise Linux

You should now vary off your partition and configure the NWSD for running Red Hat Enterprise

Linux, rather than installing it. You should change your IPL Source to either B or *NWSSTG. If

you change it to *NWSSTG (booting off of your PPC PReP boot partition) you also need to add

IPL Parameters. Now when you vary on your NWSD it boots up to your installed system.
Note that users installing exclusively to native SCSI disks cannot boot from *NWSSTG.
Remember that the only place you can log in as root is at the console or other devices as listed in

/etc/securetty

. If you want to log in as root from remote systems, use

ssh

pSeries — Completing the Installation

Do not forget to remove any diskette in the diskette drive or CD in the CD-ROM drive.
After rebooting, you must set the open firmware boot device to the disk containing your Red Hat

Enterprise Linux PReP and / partitions. To accomplish this, wait until the LED indicator says

E1F1

, then press [F1] to enter the

System Management Services

GUI. Click on

Multiboot

and

then click on

Boot Sequence

. Select the disk containing your Red Hat Enterprise Linux and type

. Set the other devices as you wish, then click on

Save

, then

Exit

. Click on

Exit

from the main

menu to boot your new system.
After your computer’s normal power-up sequence has completed, YABOOT’s prompt appears,

at which you can do any of the following things:

•

Press [Enter] — causes YABOOT’s default boot entry to be booted.

•

Select a boot label, followed by [Enter] — causes YABOOT to boot the operating system

corresponding to the boot label. (Press [Tab] for pSeries systems at the

boot:

prompt for a

list of valid boot labels.)

•

Do nothing — after YABOOT’s timeout period, (by default, five seconds) YABOOT automat-

ically boots the default boot entry.

Once Red Hat Enterprise Linux has booted, one or more screens of messages should scroll by.

Eventually, a

prompt or a GUI login screen (if you installed the X Window System and

chose to start X automatically) appears.

The first time you start your Red Hat Enterprise Linux machine in run level 5 (the graphical run level),

the

Setup Agent

is presented, which guides you through the Red Hat Enterprise Linux configuration.

Using this tool, you can set your system time and date, install software, register your machine with

Red Hat Network, and more. The

Setup Agent

lets you configure your environment at the beginning,

so that you can get started using your Red Hat Enterprise Linux system quickly.
If you are not sure what to do next, we suggest you begin with the other Red Hat Enterprise Linux

manuals available online or on the Red Hat Enterprise Linux Documentation CD included with your

Red Hat Enterprise Linux product.
HTML, PDF, and RPM versions of the manuals are available on the Red Hat Enterprise Linux Docu-

mentation CD and online at http://www.redhat.com/docs/.

Note

Although this manual reflects the most current information possible, read the

Red Hat Enterprise

Linux Release Notes

for information that may not have been available prior to our documenta-

tion being finalized. They can be found on the Red Hat Enterprise Linux CD #1 and online at

http://www.redhat.com/docs/.
