Red Hat Enterprise Linux 5 5.3 Release Notes - Red Hat Customer ...

compatible with existing single-machine mirrors. When switching a mirrored logical volume
between single-machine and cluster-aware, no resynchronization is necessary.
1.2. Resolved Issues
system-config-network requires the fonts provided with xorg-x11-fonts-Type1 in order to
display. However, this fonts package was not previously set as a dependency for system-confignetwork
and it was therefore possible (for example, in the case of a minimal installation) for
system-config-network to be present on a system and yet unable to function because these
fonts were missing. This update sets xorg-x11-fonts-Type1 as a dependency for systemconfig-network
to ensure that these fonts will be available and that system-config-network
will display correctly.
In Red Hat Enterprise Linux 5.2, a 64-bit version of httpd was included in addition to the existing 32bit
httpd in the PowerPC architecture. If a user installed both versions, an httpd conflict would
occur, preventing httpd from functioning properly.
To resolve this issue, the 64-bit version of httpd has been removed from this release. Any systems
with the previous 64-bit version of httpd installed should remove the package before upgrade.
1.3. Driver Updates
the SCSI device handler infrastructure (scsi_dh) has been updated, providing added support for LSI
RDAC SCSI based storage devices.
the tg3 driver for Broadcom Tigon3 ethernet devices has been updated to version 3.93. This applies
several upstream changes for new hardware. However, the 5785 hardware is not fully supported.
This device may be detected by the driver, but lack of PHY support may cause these chips to not
function correctly and may require the user disable any on-board 5785 cards in the system BIOS.
scsi-target-utils now features iSCSI Extensions for RDMA (iSER), which is based on the Linux
Target (tgt) framework. iSER is included in this release as a Technology Preview, and provides
capabilities for both single and multiple portals on different subnets. Note, however, that there are
known bugs with using multiple portals on the same subnet.
To set up an iSER target component, install the scsi-target-utils and libibverbs-devel
packages. The corresponding library package for your system's Infiniband hardware is also required.
For example, in HCAs that use the cxgb3 driver the libcxgb3 package is needed, and for HCAs
using the mthca driver the libmthca package is need.
The MPT Fusion driver has been updated to version 3.04.06, providing the following bugfixes and
enhancements:
Previously, the MPT Fusion driver always allocated I/O resources, even if they were not required,
which may have caused issues in low resource environments. With this update, the driver now
uses the pci_enable_device_mem and pci_enable_device functions to differentiate the resource
allocations.
Previously, the kernel would panic when the mptsas and mptcl modules were loaded in parallel.
With this update, this issue has been resolved.
Previously, system power state changes (such as hibernation and standby) were not functioning
correctly with 106XE controllers. With this update, the driver has been modified to free and
allocate resources in power management entry points.
1.4 . Virtualization
Ein Fehler im IDE/ATA Treiberstapel, der ein kernel-xen verwendendes Systemvom Booten in die
kdump-Umgebung hindern konnte, wurde jetzt behoben. In früheren Releases trat dieser auf, wenn
das System auf eine Kernel Panik traf während das IDE-Gerät I/O durchführte und das IDE-Gerät
durch einen Gerätetreiber gesteuert wurde, bei dem es sich nicht um libata handelte.
A softlockup may have occurred when creating a guest with a large amount of memory.
