3.5.1 Matrix Server Upgrade Guide

Chapter 3: Double Rolling Upgrades 30

Double Upgrade Without MxFS-Linux

This procedure should be used only if you are running Matrix Server 3.1.2

on a 32-bit operating system and want to move to Matrix Server 3.5.1 on a

64-bit operating system. The procedure is a double upgrade. The first

upgrade installs Matrix Server 3.5.1 on the 32-bit operating system. When

all servers are running Matrix Server 3.5.1, the second upgrade is done to

take the operating system to 64-bit mode. Matrix Server must then be

reinstalled to take advantage of 64-bit mode.

Complete the following steps to perform the upgrade.

NOTE: Upgrade the server with the highest IP address first. Then

continue to upgrade the servers in descending order of IP address,

with the lowest numbered server being upgraded last.

1. Stop Matrix Server on the server:

# /etc/init.d/pmxs stop

2. Back up the Matrix Server configuration as described under “Back Up

and Restore the Matrix Configuration” on page 3.

3. If the following Matrix Server configuration files have been modified

at your site, save copies of the files. After the second installation of

Matrix Server, you can merge your local changes into the new versions

of the files.

/etc/opt/polyserve/mxinit.conf

/etc/opt/polyserve/scl.conf

/etc/opt/polyserve/fc_pcitable

/etc/opt/polyserve/san_snmp.conf

4. If you will be performing a fresh installation of the operating system,

skip to step 9. Otherwise, continue with the following steps.

5. If the Matrix Server Support RPM is installed, uninstall it:

# rpm -e pmxs-<os>-support

6. Uninstall any Matrix Server patches installed on the server:

# rpm -e pmxs-patch
