3.1.2 Matrix Server Upgrade Guide

Appendix A: Install the RHEL4 Operating System and Kernel 59

4. Modify the EXTRAVERSION variable to identify the patched Matrix

Server kernel. The variable is located in the Makefile in the directory /

usr/src/linux-<kernel>. The variable specifies the portion of the kernel

name that follows the kernel version number (2.6.9 in our example).

The variable must be set to the name used by the binary RHEL4

kernel. This is typically the build number. You may also want to add a

suffix that identifies the kernel environment, such as PS or PolyServe

to indicate that the kernel was built for PolyServe Matrix Server. For

example, if you are building the Red Hat 2.6.9-34.ELsmp kernel,

EXTRAVERSION would contain the following:

EXTRAVERSION = -34.ELsmp-PS

NOTE:

Some third-party software requires that the kernel name match

the binary kernel name exactly. If you are using such software,

do not include a suffix to identify the kernel environment.

Install the Matrix Server Support RPM

The Support RPM contains Matrix Server support files for each kernel

supported in the release. To install the Support RPM, mount the

PolyServe CD on /mnt/cdrom or go to the location where you downloaded

the software and then run the following command. Be sure to install the

version of the RPM that corresponds to your architecture (i586 for 32-bit

or x86_64 for 64-bit).

# rpm -i <mountpoint>/pmxs-rhel4-support-3.1.2-<xxxx><arch>.rpm

The installation creates a subdirectory in /usr/src/polyserve for each kernel

provided in the RPM. Each kernel subdirectory contains the following:

•A configs subdirectory containing sample configuration files for that

kernel.

•A patches subdirectory containing the PolyServe kernel patches for

that kernel.

• The KDB patch required to build a debug kernel.

Install the PolyServe Kernel Patches

You can now patch the kernel source with the PolyServe kernel patches

provided in the PolyServe Support RPM. Before beginning, verify that the
