Support Notes for Red Hat Enterprise Linux 5 Announcement HP has certified Red Hat Enterprise Linux (RHEL) 5 for the Intel® Itanium Processor® (kernel 2.6.18-8.el5; glibc-2.5-12) on HP Integrity servers. For a list of the HP servers supported by RHEL 5, see the Linux 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 installation number that each customer receives from HP when ordering either RHEL.
Known Issues 1. HP has identified an issue with the RHEL5 ext3 file system which under some conditions may result in system panics. Red Hat has provided an errrata to include a correction for this issue. This errata is available to subscribers of the Red Hat Network at the following URL: http://rhn.redhat.com/errata/RHSA-2007-0376.html HP recommends that you install this errata. 2. 3. For the RHEL 5 pre-install, HP uses the non-virtualized kernel, kernel-2.6.18-8.el5.
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. 32-bit emulation is not automatically installed with Red Hat Enterprise Linux 5.
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. When rebooting the system, the user should either manually confirm the system has booted, or use scripts to track the system boot on the serial console and automatically intervene as necessary. The only intervention required to continue the boot process is to send a character to produce a receiver interrupt on the console UART (for example, pressing a key).
This does not cause a system crash or affect system operation, but it produces alarming kernel messages. 25. The HP Array Configuration Utility Command Line Interface (hpacucli) create commands can cause kernel panics. The hpacucli command is used to create logical drives in the MSA disk arrays. A fix will be applied to future versions of the CCISS driver. Until a fix is available, HP recommends that you use the ORCA.EFI utility to create volumes.
