Upgrading Serviceguard to SGeRAC cluster

Beginning with HP-UX 11i v3 1109 HA-OE/DC-OE, SGeRAC is included as a licensed bundle at no additional cost. To install SGeRAC A.11.20 on your system during OE installation, you must select T1907BA (SGeRAC) in the Software tab.

The following sections discuss the different scenarios for including SGeRAC while upgrading from an earlier OE to HP-UX 11i v3 1109 HA-OE/DC-OE in a Serviceguard environment.

Upgrading from an existing SGeRAC A.11.19 cluster to HP-UX 11i v3 1109 HA-OE/DC-OE

To upgrade from an existing Serviceguard and SGeRAC A.11.19 deployment to HP-UX 11i v3 1109 HA-OE/DC-OE, you must select the licensed SGeRAC A.11.20 bundle available in the HP-UX 11i v3 1109 HA-OE/DC-OE media.

NOTE: You must select the product SGeRAC T1907BA when upgrading to HP-UX 11i v3 1109 HA-OE/DC-OE, otherwise Serviceguard A.11.20 installation will fail.

To perform rolling upgrade for an SGeRAC cluster with Oracle RAC configured, the HP-UX OS version must be the same, that is, either 11i v2 or 11i v3. If you upgrade from 11i v2 to 11iv3, you can perform an offline upgrade or rolling upgrade. For more information see, “Non-Rolling Software Upgrades” (page 148) section and “Steps for Rolling Upgrades ” (page 142).

NOTE: For all the scenarios discussed in the following sections, HP recommends that the method used to upgrade from Serviceguard A.11.19 to Serviceguard A.11.20 and SGeRAC A.11.20

must be an offline upgrade. Using Dynamic Root Disk (DRD) utilities can significantly reduce the planned maintenance time to perform the upgrade.

If you want to perform a rolling upgrade that includes SGeRAC, then you must follow 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) onwards.

To perform an offline upgrade

1.Halt the cluster. Use the following command: cmhaltcl -f

2.Upgrade all the nodes in the cluster to the new HP-UX release 1109 and select SGeRAC A.11.20 during the upgrade.

3.Restart the cluster using the following command: cmruncl

Upgrading from an existing Serviceguard A.11.19 cluster to HP-UX 11i v3 1109 HA-OE/DC-OE along with SGeRAC

To upgrade from Serviceguard A.11.9 cluster to HP-UX 11i v3 1109 HA-OE/DC-OE along with SGeRAC:

1.Install Serviceguard A.11.19 patch PHSS_42216 on all the cluster nodes before upgrading from Serviceguard A.11.19 to HP-UX 11i v3 1109 HA-OE/DC-OE, Serviceguard and SGeRAC A.11.20. Otherwise, upgraded Serviceguard and SGeRAC A.11.20 node will not be able to join the existing 11.19 cluster.

2.Select the licensed SGeRAC A.11.20 bundle. To upgrade the 1109 HA-OE/DC-OE: On the first node:

a. Halt the node using the following command:
