Once the beta channel has been subscribed, run the following command 
from a shell prompt on each target system to update any packages for
which new versions exist:


You will see a list of packages that are available to be installed.
Select all packages and step through the instructions.  Note: you will
optionally be able to skip installation of the kernel.  Do not skip the
kernel!  Be sure to select it as well for installation.

For more information, Red Hat Network user guides and FAQs are 
available on the RHN website at https://rhn.redhat.com.

* Note: Systems that are updated with the beta update will not be

              Red Hat Enterprise Linux 4 Update 1 Release Notes

   Copyright (c) 2005 Red Hat, Inc.



   The following topics are covered in this document:

     o Changes to the Red Hat Enterprise Linux installation program

     o General information

     o Changes to drivers and hardware support

Changes to the Red Hat Enterprise Linux Installation Program (Anaconda)

   The following section includes information specific to the Red Hat
   Enterprise Linux installation program, Anaconda.


   In order to upgrade an already-installed Red Hat Enterprise Linux 4 system
   to Update 1, you must use Red Hat Network to update those packages that
   have changed.

   You may use Anaconda to perform a fresh installation of Red Hat Enterprise
   Linux 4 Update 1 or to perform an upgrade from the latest updated version
   of Red Hat Enterprise Linux 3 to Red Hat Enterprise Linux 4.

     o If you are copying the contents of the Red Hat Enterprise Linux 4
       Update 1 CD-ROMs (in preparation for a network-based installation, for
       example) be sure you copy the CD-ROMs for the operating system only.
       Do not copy the Extras CD-ROM, or any of the layered product CD-ROMs,
       as this will overwrite files necessary for Anaconda's proper

       These CD-ROMs must be installed after Red Hat Enterprise Linux has
       been installed.

General Information

   This section contains general information not specific to any other
   section of this document.

     o Red Hat Enterprise Linux 4 Update 1 now includes the diskdump
       facility,which can serve as an alternative to (or be used in
       conjunction with) the Red Hat netdump facility.

       The diskdump facility for i386 systems currently support the aic7xxx,
       aic79xx, mpt fusion, megaraid, and SATA devices. On ia64 systems, the
       aic7xxx, aic79xx, mpt fusion, and SATA devices are supported. On AMD64
       and Intel(R) EM64T systems, the aic7xxx, aic79xx, mpt fusion,
       megaraid, and SATA devices are supported. Finally, on PPC64 systems,
       the ipr and sym53c8xx_2 devices are supported.


       The megaraid and SATA devices are newly supported in Red Hat
       Enterprise Linux 4 Update 1.

       Usage of the diskdump facility requires a dedicated disk device or
       disk partitions that are large enough to contain all physical system
       memory. In the event of a system crash, memory will be written to the
       configured disk location. Upon subsequent reboot, the data will be
       copied from the configured disk location and formatted into a vmcore
       file, identical in functionality to that created by the netdump
       facility, and stored in the unique subdirectory /var/crash/. The
       vmcore file may be analyzed using the crash(8) utility.


       The diskdump facility may fail to write a dump file if cluster mode is
       enabled on megaraid adapters. You can disable cluster mode on megaraid
       adapters using the device's WebBIOS utility. Consult your manufacturer
       documentation for more information on using WebBIOS.

       The kernel modules required for the diskdump facility are
       automatically included in the Red Hat Enterprise Linux 4 kernel. The
       associated user-space diskdump package is named diskdumputils-1.0.0,
       and like netdump, is installed by default.

       The available and appropriate disk location must first be configured
       and then preformatted for use. After formatting, the diskdump facility
       may be turned on with chkconfig(8), and then the service must be
       started. Detailed documentation concerning configuration and user
       tasks is included with the diskdumputils at the following:


       Further information can be found in the diskdumpfmt(8),
       diskdumpctl(8), and savecore(8) man pages.

Changes to Drivers and Hardware Support

   This update includes bug fixes for a number of drivers. The more
   significant driver updates are listed below. In some cases, the original
   driver has been preserved under a different name, and is available as a
   non-default alternative for organizations that wish to migrate their
   driver configuration to the latest versions at a later time.


   The migration to the latest drivers should be completed before the next
   Red Hat Enterprise Linux update is applied, because in most cases only one
   older-revision driver will be preserved for each update.
