Support Notes for Red Hat Enterprise Linux AS v.4 Update 4 Announcement HP has certified Red Hat Enterprise Linux (RHEL4) AS v.4 Update 4 for the Intel® Itanium Processor® (kernel 2.6.9-42.EL; glibc-2.3.4-2.25) 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.
Known Issues 1. HP does not recommend using the drivers in the RHEL4 Update 4 installation for the A6826A, A7538A, AB379A, AD167A, orAD168A cards. To obtain the drivers that HP supports for the A6826A, A7538A, AB379A, AD167A, AD168A, AB429A, AD300A, AE311A, A8002A, or A8003A cards, respectively: a.

10. The Red Hat Enterprise Linux AS v. 4 kernel supports maximum memory of 2 TB, which is also supported by HP. 11. No support for uncertified .rpm packages. If you add uncertified .rpm packages to the operating system, the operating system will not be supported by Red Hat. Red Hat supports only .rpm packages bundled in supported Linux distributions for Integrity servers and official Red Hat Updates for those distributions. HP supports the Linux software it distributes. 12. Red Hat Enterprise Linux AS v.
slots have a unique address. Although your server should have the correct setting already, confirm it before proceeding and change it if necessary using the following instructions: a. From the EFI shell, enter acpiconfig. b. You should see the following output: acpiconfig settings: single-pci-domain If you see something different, continue to the next step to reset the value. Otherwise, stop here. c. To set the ACPI configuration value to single-pci-domain: 1.
22. Output from the Management Processor (MP) serial ports may hang due to a failure to reassert a transmit empty interrupt in the MP UART. When used as a serial console, this output hang may lead to a hang during Linux boot. This condition may occur on any low-end Integrity system using the MP console port as the Linux system console. This problem does not exist on mid-range and high-end Integrity platforms.
Integrity Superdome systems with five or more cells (threads enabled), or nine or more cells (threads disabled) need the largesmp kernel. A standard RHEL4 installation works even when more than 64 CPUs are present, but ignores extra CPUs. After the installation, manually install the largesmp kernel. For RHEL4 U4, this is the command: # rpm -i RedHat/RPMS/kernel-largesmp-2.6.9-42.EL.ia64.rpm A reboot is required after installing the largesmp kernel.
The elilo boot loader is the IA-64 initial program loader that starts the Linux kernel (both for installations and post-install). Normally, systems are configured to automatically boot without any user intervention. This workaround around requires user intervention as follows. During installation, when the system prints the ELILO: prompt, you must enter a string to override the default boot parameters.
