availability. When Oracle binaries are relinked from an upgraded node, only
upgraded nodes can support a failover. Servers still running the old version of
the operating system will not be able to use the relinked Oracle Home. Although
the servers will still be candidates for failover, they will not be able to support a
failover until they are upgraded. Consequently, HP recommends that you do not
relink binaries until all of the cluster nodes have been upgraded.
Oracle installation information
See the articles referenced in Metalink articles, page 62, for extensive information
about installing Oracle.
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
