2.23. Installation Complete

Congratulations! Your Red Hat Enterprise Linux installation is now complete!

The installation program prompts you to prepare your system for reboot.

OpenPower, p5, i5, and pSeries — Completing the Installation

Do not forget to remove any boot media.

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 or HMC SRC says E1F1, then press [1] to enter the System Management Services GUI. Click on Select Boot Options. Select Select Boot Devices. Select Configure 1st Boot Device. Select the disk containing Red Hat Enterprise Linux. Set the other devices as you wish. Then exit the SMS menus to boot your new system.


Steps in the SMS menu may be different depending on the machine model.

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 non-iSeries systems at the boot: prompt for a list of valid boot labels.)

  • Do nothing — after YABOOT's timeout period, (by default, five seconds) YABOOT automatically boots the default boot entry.

Once Red Hat Enterprise Linux has booted, one or more screens of messages should scroll by. Eventually, a login: prompt or a GUI login screen (if you installed the X Window System and chose to start X automatically) appears.

iSeries — Completing the Installation

When the installation program completes, it prompts you to press the [Enter] key. The LPAR then reboots with the installed Red Hat Enterprise Linux OS.

The installation program has completed the following tasks:

  • Installed a kernel to the B slot and kernel parameters ro root=LABEL=/

  • Installed a kernel to the PPC PReP boot partition, if one exists

  • The A slot has been left alone for the users discretion


iSeries users may also find the following information about kernel slots useful:


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.

The first time you start your Red Hat Enterprise Linux system 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.

For more information on using the Setup Agent, refer to the chapter titled Getting Started in the Red Hat Enterprise Linux Step By Step Guide.
