Installation guide

There are some video cards that have trouble booting into the graphical installation program. If the
installation program does not run using its default settings, it tries to run in a lower resolution mode.
If that still fails, the installation program attempts to run in text mode.
One possible solution is to try using the resolution= boot option. Refer to Chapter 15, Additional
Boot Options for IBM Power Systems for more information.
Note
To disable frame buffer support and allow the installation program to run in text mode, try
using the nofb boot option. This command may be necessary for accessibility with some
screen reading hardware.

14 .3.1. No devices found to install Red Hat Enterprise Linux Error
Message
If you receive an error message stating No devices found to install Red Hat Enterprise
Linux, there is probably a SCSI controller that is not being recognized by the installation program.
Check your hardware vendor's website to determine if a driver diskette image is available that fixes
your problem. For more general information on driver diskettes, refer to Chapter 13, Updating drivers
during installation on IBM POWER systems.
You can also refer to the Red Hat Hardware Compatibility List, available online at:

14 .3.2. Saving T raceback Messages Wit hout a Disket t e Drive
If you receive a traceback error message during installation, you can usually save it to a diskette.
If you do not have a diskette drive available in your system, you can scp the error message to a
remote system.
This information does not apply to users of headless IBM System p systems.
When the traceback dialog appears, the traceback error message is automatically written to a file
named /tmp/anacdump.txt. Once the dialog appears, switch over to a new tty (virtual console) by
pressing the keys Ctrl+Alt+F2 and scp the message written to /tmp/anacdump.txt to a
known working remote system.

Setup” ) phase of the installation saying something similar to
The partition table on device hda was unreadable. To create new partitions it must be
initialized, causing the loss of ALL DATA on this drive.
you may not have a partition table on that drive or the partition table on the drive may not be
recognizable by the partitioning software used in the installation program.
