3.7.0 HP StorageWorks HP Scalable NAS File Serving Software upgrade guide HP Scalable NAS for Linux (AG513-96005, October 2009)

5 Upgrade Matrix Server only
Upgrades to HP Scalable NAS File Serving Software 3.7.0 are supported only from
Matrix Server 3.5.1. If the Management Console is installed on client machines, you
will also need to upgrade that software.
Upgrade considerations
You should be aware of the following when upgrading to the HP Scalable NAS 3.7.0
release.
Order for upgrading servers
Servers must be upgraded one-at-a-time during the upgrade. The server with the
numerically highest primary IP address must be upgraded first. Then continue to
upgrade the servers in descending order of IP address, with the server with the lowest
primary IP address being upgraded last.
If you have two networks and the IP addresses are ordered differently on each
network, you will need to determine the IP addresses by which the servers are known
to the cluster and then use those addresses to determine the order for the upgrade.
For example, the servers could have the following network interfaces:
server srv1: network interfaces 10.10.1.1 and 11.10.2.3
server srv2: network interfaces 10.10.1.2 and 11.10.2.2
server srv3: network interfaces 10.10.1.3 and 11.10.2.1
Run the command mx --numeric server status to determine the IP addresses
known to the cluster. In our example, the output is as follows and indicates that srv3
(primary IP address 10.10.1.3) should be upgraded first.
10.10.1.1
10.10.1.2
10.10.1.3
