Installation guide

Appendix C. Troubleshooting Your Installation of Red Hat Enterprise Linux 63
One possible solution is to try using the resolution= boot option. This option may be most helpful
for laptop users. Refer to Appendix F Additional Boot Options 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.
C.3. Trouble During the Installation
C.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 Appendix E Driver Media.
You can also refer to the Red Hat Hardware Compatibility List, available online at:
http://hardware.redhat.com/hcl/
C.3.2. Saving Traceback Messages Without a Diskette 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.
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.
C.3.3. Trouble with Partition Tables
If you receive an error after the Disk Partitioning Setup (Section 4.14 Disk Partitioning 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 recog-
nizable by the partitioning software used in the installation program.
Users who have used programs such as EZ-BIOS have experienced similar problems, causing data to
be lost (assuming the data was not backed up before the installation began) that could not be recovered.
No matter what type of installation you are performing, backups of the existing data on your systems
should always be made.
