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

This command removes all files associated with MxODM and restores Oracle to its
configuration before MxODM was installed. Be sure to consider the resulting changes
to the performance characteristics during your upgrade testing.
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
NOTE:
If a server is accidentally upgraded out of order, when a higher-numbered server
joins the cluster, the servers still running the old version of Matrix Server will think
they need to leave the cluster and will no longer send configuration and status
updates. To correct this problem, stop HP Scalable NAS on the node that was
upgraded out of order. Continue upgrading the other nodes before starting HP
Scalable NAS on that node.
Recommended upgrade methodology
Before preceding with the upgrade, be sure to review and complete the actions
described in Upgrade considerations and preconditions, page 45.
