Using Serviceguard Extension for RAC, 10th Edition, April 2011

NOTE: While you are performing a rolling upgrade, warning messages may appear while the
node is determining what version of software is running. This is a normal occurrence and not a
cause for concern.

Step 1.
1. Halt Oracle (RAC, Clusterware) software on node 1.
2. Halt node 1. This will cause the node’s packages to start up on an adoptive node. You can
do this in Serviceguard Manager, or from the command line issue the following:
# cmhaltnode -f node1
This will cause the failover package to be halted cleanly and moved to node 2. The Serviceguard
daemon on node 1 is halted, and the result is shown in Figure 21.
