2. Run the command exportfs -ua on each server where the filesystem

will be unmounted.

3. Unmount the filesystem from the servers. If you see a “device busy”

message, run the exportfs -ua command again and then repeat the

unmount operation.

Matrix Server 2.7.2

This procedure is a double upgrade. The first upgrade takes the operating

system to RHEL4 or SLES9 SP2 in 32-bit mode and takes Matrix Server to

3.1.2. When all servers are running Matrix Server 3.1.2, 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.

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

the Existing Matrix” on page 2.

2. Stop Matrix Server on the server:

# /etc/init.d/pmxs stop

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/polyserve/mxinit.conf

/etc/polyserve/scl.conf

/etc/polyserve/fc_pcitable

/etc/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. Uninstall the Matrix Server Support RPM, if installed:

# rpm -e pmxs-<os>-support
