Refer the procedures described in the scenario “ Upgrading from an existing Serviceguard
A.11.19 cluster to HP-UX 11i v3 1109 HA-OE/DC-OE along with SGeRAC” (page 140) to
perform rolling upgrade from Serviceguard A.11.19 to HP-UX 11i v3 1109 HA-OE/DC-OE

this upgrade.
Upgrading from Serviceguard A.11.20 cluster to HP-UX 11i v3 1109 HA-OE/DC-OE along with
SGeRAC
To upgrade from Serviceguard A.11.20 to HP-UX 11i v3 1109 HA-OE/DC-OE:
1. Install Serviceguard A.11.20 patch PHSS_42137 on all the cluster nodes before you start
upgrading to HP-UX 11i v3 1109 HA-OE/DC-OE.
NOTE: If Serviceguard A.11.20 patch PHSS_42137 is not installed on the upgraded
Serviceguard A.11.20 node, when you install SGeRAC on a node, it will not be able to join
the existing Serviceguard A.11.20 cluster.
2. Select the licensed SGeRAC A.11.20 bundle to upgrade each node to HP-UX 11i v3 1109
HA-OE/DC-OE. To upgrade to HP-UX 11i v3 1109 HA-OE/DC-OE:
On the first node:
a. Halt the node using the following command:
cmhaltnode <node_name>
b. Select the SGeRAC bundle T1907BA while upgrading the node to HP-UX 11i v3 1109
HA-OE/DC-OE.
NOTE: In this state, if you try the commands like cmcheckconf and cmapplyconf on the
cluster configuration file, no Error or Warning message related to the missing SGeRAC software
are displayed.
3. Run the following command to join the upgraded node to the cluster:
cmrunnode <node_name>
NOTE: Please make sure that Serviceguard Extension for RAC is installed on all nodes in
the cluster and all nodes are up and running before attempting to deploy Oracle RAC in this
cluster.
4. Repeat steps 2 to 3 for all then nodes in the cluster to complete the upgrade.
Steps for Rolling Upgrades
Use the following steps when performing a rolling SGeRAC software upgrade:
1. Halt Oracle (RAC, Clusterware) software on the local node (if running).
2. Halt Serviceguard/SGeRAC on the local node by issuing the Serviceguard cmhaltnode
command.
3. Edit the /etc/rc.config.d/cmcluster file to include the following line:
AUTOSTART_CMCLD = 0
4. Upgrade the HP-UX OS (if required), Serviceguard, and SGeRAC to the new release (SGeRAC
requires the compatible version of Serviceguard and OS). For more information on how to
upgrade HP-UX, see HP-UX Installation and Update Guide for the target version of HP-UX.
5. Edit the /etc/rc.config.d/cmcluster file, on the local node, to include the following
line:
AUTOSTART_CMCLD = 1
