8 Troubleshooting

You may encounter problems during the FSE installation, upgrade, and uninstallation process. Before you contact HP technical support, you should verify that all the prerequisites are met and that you have followed the corresponding procedures as described in this guide, including, for example, the operating system preparation phase. See also the FSE release notes for additional problems related to installation, upgrade, and uninstallation.

This chapter includes the following topics:

•General problems, page 67

•Installation problems, page 67

General problems

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.

Installation problems

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.
