For further information on software based FCoE refer to: http://www.open-fcoe.org/openfc/wiki/
index.php/FCoE_Initiator_Quickstart.
Red Hat Enterprise Linux 5.3 provides full support for FCoE on three specialized hardware
implementations. These are: Cisco fnic driver, the Emulex lpfc driver, and the Qlogic qla2xx
driver.
iSER Support
iSER support, allowing for block storage transfer across a network, has been added to the scsi-
target-utils package as a Technology Preview. In this release, single portal and multiple
portals on different subnets are supported. There are known bugs when using multiple portals on
the same subnet.
To set up the iSER target component install the scsi-target-utils and libibverbs-devel RPM. The
library package for the InfiniBand hardware that is being used is also required. For example:
host channel adapters that use the cxgb3 driver the libcxgb3 package is needed, and for host
channel adapters using the mthca driver the libmthca package is needed.
There is also a known issue relating to connection timeouts in some situations. Refer to Red Hat
Bugzilla #470627

for more information on this issue.
2. Installation-Related Notes
This section includes information specific to Anaconda and the installation of Red Hat Enterprise
Linux 5.3.
Red Hat Network can install the new and changed packages and upgrade an existing Red Hat
Enterprise Linux 5 system. Alternatively, Anaconda can upgrade an existing Red Hat Enterprise Linux
5 system or perform a fresh installation of Red Hat Enterprise Linux 5.3.
Note: upgrading from beta releases of Red Hat Enterprise Linux 5.3 to this GA release is not
supported.
Further, although Anaconda provides an option for upgrading from earlier major versions of Red
Hat Enterprise Linux to Red Hat Enterprise Linux 5.3, Red Hat does not currently support this. More
generally, Red Hat does not support in-place upgrades between any major versions of Red Hat
Enterprise Linux. (A major version is denoted by a whole number version change. For example, Red
Hat Enteprise Linux 4 and Red Hat Enterprise Linux 5 are both major versions of Red Hat Enterprise
Linux.)
In-place upgrades across major releases do not preserve all system settings, services or custom
configurations. Consequently, Red Hat strongly recommends fresh installations when upgrading from
one major version to another.
2.1. All Architectures
The Text Mode installation of Anaconda now offers the option of switching to Virtual Network
Computing (VNC) to complete the installation.
