Upgrade Matrix Software Without

Reinstalling the OS

This procedure is intended for sites that will not be reinstalling the

operating system during the upgrade. The procedure includes steps to

update the operating system to a later RHEL4 update or SLES9 service

pack and to install a new kernel.

Complete the following steps on all servers in the matrix:

1. Stop Matrix Server:

# /etc/init.d/pmxs stop

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

the Existing Matrix” on page 2.

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

at your site, save copies 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 are using MxFS-Linux, complete these steps:

a. Uninstall any MxFS-Linux fastpatches:

# rpm -e mxfs-fastpatch

b. Uninstall MxFS-Linux. (When you uninstall MxFS-Linux, you may

see an error message stating that a failure occurred. You can ignore

this message; the uninstall was successful.)

# rpm -e mxfs

# rpm -e mxfs-patches

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