3.1.2 Matrix Server Upgrade Guide

Appendix A: Install the RHEL4 Operating System and Kernel 60

/usr/src/polyserve directory contains the version of the kernel that you are

building.

To install the PolyServe kernel patches, complete these steps:

1. Run the following command:

# /usr/src/polyserve/mxpatch -i

A message stating that the kernel patches are being applied should

now appear.

2. To verify that the patches have been applied to the kernel source, run

the following command:

# /usr/src/polyserve/mxpatch -v

Compile the Kernel

Following is a suggested procedure that you can use as a guide for

building the kernel. Modify this procedure as necessary for your local

circumstances.

NOTE: If the servers have identical hardware configurations, you can

create the kernel on one server and then copy it to the other

servers.

1. Go to the /usr/src/linux-<kernel> directory on the server and run the

make mrproper command.

# cd /usr/src/linux-<kernel>

# make mrproper

2. The Matrix Server Support RPM includes sample configuration files

that are recommended for use with the Linux kernel and Matrix

Server. The files are based on the configuration files provided by Red

Hat and are placed in the /usr/src/polyserve/<kernel>/configs directory.

The files provided for the 32-bit kernel are for the following systems:

• ps_config.i686. Uniprocessor systems using an i686 chip.

• ps_config.i686-smp. SMP systems using an i686 chip.

• ps_config.i686-hugemem. Systems using an i686 chip and having

4-GB of user-address space.
