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

Step 2.
Upgrade node 1 and install the new version of Serviceguard and SGeRAC (A.11.16), as shown
in Figure 22.
NOTE: If you install Serviceguard and SGeRAC separately, Serviceguard must be installed before
installing SGeRAC.

Step 3.
1. If you prefer, restart the cluster on the upgraded node (node 1). You can do this in Serviceguard
Manager, or from the command line issue the following:
# cmrunnode node1
2. At this point, different versions of the Serviceguard daemon (cmcld) are running on the two
nodes, as shown in Figure 23.
3. Start Oracle (Clusterware, RAC) software on node 1.
