Support Notes for Red Hat Enterprise Linux AS 4.7 for HP Integrity Servers

2. Signal the init process to re-read the inittab file with the following command:
kill -HUP 1
3. If you are logged in to the console, exit then log in again to restart the agetty process.
Installation
• Installation failure when using autopartition
The installation of RHEL AS 4.7 might fail if using the autopartition function on a server
with multiple disks.
If you encounter this issue, remove all disks from the server except those on which you are
installing RHEL AS 4.7. Replace the removed disks once the OS installation on the targeted
disks is complete. You may then need to edit the device file name of the /boot/efi mount
point in the /etc/fstab file because the device file may have changed when the disks
were replaced.
• Simultaneous installations of RHEL 3 and 4
If you have RHEL AS 3 installed on a disk partition on your server and want to install RHEL
AS 4.7 on another, you must change the name of your boot manager entry on the RHEL AS
3 partition. This is because RHEL 3 and 4 use the same name for the boot manager entry.
Before installing RHEL AS 4.7, you must change the name of the RHEL AS 3 boot entry. The
EFI Boot Manager does not have a rename function to use to rename the RHEL AS 3 entry
so you have to add a new boot entry.
To add a new EFI boot entry, select the Boot Option Maintenance menu (also called Boot
Configuration in new EFI Boot Managers), and then add a new boot entry for RHEL AS 3
using a unique name with the same boot parameters as the existing RHEL AS 3 entry.
• Load order of drivers may be altered
If you are transitioning to RHEL AS 4.7 from either RHEL 3 or RHEL 2.1, recognize that the
load order of storage and networking drivers in this OS version is the reverse of the order
in RHEL AS 3 and 2.1. The numbers on the device file names for your NICs appear in the
opposite order than the previous versions of RHEL.
• Load of RHEL failed error
After installing the operating system, if a message similar to the following is displayed, you
must take action.
Loading.: Red Hat Enterprise Linux Load of Red Hat Enterprise Linux
failed: Not Found Press any key to continue
Execute the following steps from the EFI shell:
1. Enter the following commands to reconnect and regenerate all mappings:
Shell> reconnect -r
Shell> map -r
2. Boot to the operating system by exiting the shell by entering exit.
3. Select the EFI boot menu entry for the installed operating system.
Kernel
• HP SAS Integrated Raid (IR) Configuration Utility May Cause Kernel Panics
The Integrated Raid (IR) Configuration Utility, cfggen, is a Linux command line utility
that configures the IR functionality of the HP Serial Attached SCSI (SAS) controllers that
are used in LSI-1068-based HP SAS controllers. The cfggen utility causes kernel panics
when creating volumes with RHEL4U7.
