Support Notes for Red Hat Enterprise Linux AS v.4.6 Announcement HP has certified Red Hat Enterprise Linux (RHEL4) AS v.4.6 for the Intel® Itanium Processor® (kernel-2.6.9-67.EL; glibc-2.3.4-2.39) on HP Integrity servers. For a list of the HP servers supported by RHEL4, see the Linux on Integrity certification matrix at the following Web site: www.hp.
CD to install additional utilities and tools such as HP system management software. For instructions, see Operating System Installation (page 6). The HP Smart Setup CD ships with your system hardware and is also available for free download under the Linux link at the following Web site: http://www.hp.com/go/integritylinuxessentials Documentation Red Hat provides its own installation guide for operating system installation.
Downloading RHEL from the Red Hat Web Site You can choose to download the RHEL operating system directly from the Red Hat Web site and not receive a media kit from HP containing the software. This scenario occurs when the media option AJR is deselected from the order. (The media kit option is always selected by default. ) It is necessary to register at the Red Hat Web site prior to download. Registration requires the activation code that each customer receives from HP when ordering either RHEL.

12. This issue affects Linux running on all Integrity systems. The Management Processor UART on these systems does not supply the Carrier Detect signal. This causes applications to hang when opening the UART device, waiting for Carrier Detect, unless they use the O_NDELAY or O_NONBLOCK flag. For example, echo foo > /dev/ttyS0 hangs.
nPartitions, halting the operating system from an nPartition with softpowerdown enabled causes only the resources on the local nPartition to be powered off. You can run the acpiconfig command with no arguments to check the current setting and the softpowerdown setting; however, softpowerdown information is displayed only when different from normal behavior. To power on hardware that has been powered off, use the PE command at the management processor command menu.
22. System panics may occur on Integrity servers running Linux that have fibre channel (FC) storage arrays directly connected. If you plan to connect FC storage to Integrity Servers running Linux, you must connect through a FC switch. For the BL860c Blade servers, customers must use either the FC switch module (AE370A/AE371A/AE372A) or an external FC switch. 23. After installing the operating system, if a message similar to the following is displayed, you will need to take action. Loading.
