3.1.2 Matrix Server Upgrade Guide

Chapter 1: Overview 2

• The servers in the matrix can be running different versions of the same

operating system type (for example, SLES9 SP2 and SP3), as long as

the above rules are met.

• If you will be using a Matrix Server Solution Pack, it must be installed

on all nodes in the matrix.

Supported Operating System and Kernels

The supported operating systems and kernels are as follows. See the

PolyServe Hardware and Software Compatibility Guide for any updates to the

list of supported kernels. .

Back Up the Existing Matrix

Before starting the upgrade, we strongly recommend that you back up

your existing matrix:

•Back up /var/polyserve and /etc/polyserve on each server. (If you are

upgrading from 3.1.0 or 3.1.1, back up /var/opt/polyserve and

/etc/opt/polyserve.) It is important to preserve the original matrix

configuration in case you need to back out of the upgrade. You will

also need to use the backup files if you do a fresh install of the

operating system instead of an upgrade.

You will need to create separate tar files for /var/polyserve and

/etc/polyserve (or /var/opt/polyserve and /etc/opt/polyserve) using tar -cf to

preserve the permissions on the files. Be sure to copy the tar files to a

secure location such as another server.
