6 Upgrade HP Clustered
Gateway/HP 4400 Scalable NAS
systems
This chapter describes how to upgrade the following systems:
• HP Clustered Gateway 3.5.1 systems running on ProLiant DL380 G5 or DL380
G4 servers
• HP 4400 Scalable NAS systems running HP Clustered Filesystem 3.5.1
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
