Using Serviceguard Extension for RAC, 8th Edition, March 2009

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.
Figure A-1 Running Cluster Before Rolling Upgrade
Step 1.
1. Halt Oracle (RAC, CRS, Clusterware, OPS) 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 A-2.
