Description Shell command returns “Permission denied” or similar message.
Explanation You have to be logged on to the system as root in order to execute the shell commands, which
you need to run while performing the installation, upgrade, or uninstallation steps.
Workaround Make sure you are logged on as root user. You can check this with the command below:
# whoami
root
If the command responds with the user name other than root, log out from the system and log in
again with the root user name. Re-invoke the command that failed.
Description Installation process of Red Hat Enterprise Linux 4 (RHEL 4) does not detect disks in the correct
order, thus obstructing the installation from succeeding.
(Red Hat Enterprise Linux system specific)
Explanation On a system with SCSI host bus adapters attached, if kernel modules for these adapters are not
loaded in time, the disk order as detected by the RHEL 4 installation differs from that detected
by the BIOS. In this case, the actual startup disk may not be shown as being the first disk.
Workaround Start the RHEL 4 installation in expert mode and ensure the modules for the adapters attached
to the system are loaded in the appropriate sequence. For example, load the module for the
adapter to which the boot disk is connected first, followed by modules for all other adapters.
To start the RHEL 3 installation in the expert mode, boot the system from the RHEL 4 installation
CD-ROM, wait for the boot prompt, and specify the following boot options:
expert noprobe.
When you are asked to load the device drivers, load them in the appropriate order.
