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
