3.1.2 Matrix Server Upgrade Guide

Appendix A: Install the RHEL4 Operating System and Kernel 57

1. Install the Operating System

The operating system must be installed on each server that will be in a

matrix. When you perform the installation, do not place any operating-

system files on the SAN disks. To ensure that files are not installed on

these disks, you can either unplug the HBA card from the FC switch or

unplug the SAN connection before starting the installation. After booting

the server on Red Hat Linux, plug the HBA card back into the FC switch

or restore the SAN connection.

NOTE: The default Red Hat installation configures firewall rules that

prevent the correct operation of Matrix Server. PolyServe

recommends that you either select the “No firewall rules” option,

or select “Custom” and then ensure that the service ports required

by Matrix Server are open. See the PolyServe Matrix Server

Administration Guide for more information about the service ports

used by Matrix Server.

In addition to the server installation, you should also install the following

packages, which are needed to build the kernel and install kernel patches.

Matrix Server also requires that the following packages be installed.

• selinux-policy-targeted-sources

•procmail

Matrix Server modifies SELinux to allow PSFS filesystems to be mounted.

(See “Workaround for SELinux” on page 66 for details.) The selinux

package is needed to allow Matrix Server to make the necessary changes.

• binutils • glibc-devel

•cpp •glibc-kernheaders

•gcc •patch
