If you receive an error message stating No devices found to install Red Hat Enterprise Linux, then there may be an issue with your DASD devices. If you encounter this error, add the DASD=<disks> parameter to your parm file (where disks is the DASD range reserved for installation), and start the install again.
Additionally, make sure that you format the DASDs using the dasdfmt command within a Linux root shell, instead of formatting the DASDs using CMS.
If you receive an error after the Disk Partitioning Setup (Section 2.11 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 recognizable by the partitioning software used in the installation program.
No matter what type of installation you are performing, backups of the existing data on your systems should always be made.
If you are using Disk Druid to edit partitions, but cannot move to the next screen, you probably have not created all the partitions necessary for Disk Druid's dependencies to be satisfied.
You must have the following partitions as a bare minimum:
A / (root) partition
A <swap> partition of type swap
When defining a partition's type as swap, you do not have to assign it a mount point. Disk Druid automatically assigns the mount point for you.
During some upgrades or installations of Red Hat Enterprise Linux, the installation program (also known as anaconda) may fail with a Python or traceback error. This error may occur after the selection of individual packages or while trying to save the upgrade log in the /tmp/directory. The error may look similar to:
Traceback (innermost last): File "/var/tmp/anaconda-7.1//usr/lib/anaconda/iw/progress_gui.py", line 20, in run rc = self.todo.doInstall () File "/var/tmp/anaconda-7.1//usr/lib/anaconda/todo.py", line 1468, in doInstall self.fstab.savePartitions () File "fstab.py", line 221, in savePartitions sys.exit(0) SystemExit: 0 Local variables in innermost frame: self: <fstab.GuiFstab instance at 8446fe0> sys: <module 'sys' (built-in)> ToDo object: (itodo ToDo p1 (dp2 S'method' p3 (iimage CdromInstallMethod p4 (dp5 S'progressWindow' p6 <failed>
This error occurs in some systems where links to /tmp/ are symbolic to other locations or have been changed since creation. These symbolic or changed links are invalid during the installation process, so the installation program cannot write information and fails.
If you experience such an error, first try to download any available errata for anaconda. Errata can be found at:
