Red Hat Enterprise Linux 5.3 Support Notes for HP Integrity Servers

Kernel
• HP SAS Integrated Raid Configuration Utility May Cause Kernel Panics
The Integrated Raid Configuration Utility, cfggen, is a Linux command line utility that
configures the Integrated Raid functionality of the HP Serial Attached SCSI (SAS) controllers
that are used in LSI-1068-based controllers. The cfggen utility causes kernel panics when
creating volumes with RHEL 5.3.
Until this issue is resolved in the mpt driver, HP recommends that you use the EFI executable,
cfggen.efi, utility to create volumes.
If cfggen is installed on a system running RHEL 5.3, the HP Support Pack installer will
remove it.
For information about using the cfggen.efi utility, see the SmartSetup Scripting Toolkit

• Updating the MPT Fusion driver on rx2660 servers and BL860c and BL870c server blades
containing HP LSI1068 SAS controllers
The MPT Fusion driver included in RHEL 5.3 does not have the necessary agent components
required by HP System Insight Manager. This issue only effects rx2660 servers, and the
BL860c and BL870c server blades that contain an HP LSI1068 SAS controller.
If you are running HP Insight Management Agents for these SAS controllers on one of the
listed servers, you must update the MPT Fusion driver using the following steps:
1. Go to the http://www.hp.com/support/itaniumservers/ website.
2. Click on the appropriate product link for your server.
3. Click the Download drivers and software link.
4. Select a software/driver language from the list.
5. Click on the appropriate Linux distribution link.
All of the available driver and software updates are provided in a categorized listing
for your selection.
6. Click the Download button for the latest MPTLinux Driver Update for Integrity Servers
driver to download the tar file.
7. Install the driver on your system:
# rpm -ivh <downloaded driver name>
8. Reboot your system.
For additional information, see the documentation that is included with the MPT Fusion
driver update.
Hardware
• Intermittent FTP data truncation when using an HP Procurve 4108gl switch
If you are using an HP Procurve 4108gl switch on a heavily loaded system, you may
experience intermittent data truncation with FTP transfers through the network. This can
be avoided with the following steps:
1. Connect to the HP Procurve 4108gl switch using telnet or serial console, and then login.
2. From the switch command line interface, enter the config command.
3. Enter the no int all lacp command.
• System panics resulting from Fibre Channel storage arrays directly connected to the
system
System panics may occur on HP Integrity servers running RHEL when Fibre Channel storage
arrays are directly connected to the system.
