CLUSTER_INTERCONNECT_SUBNET parameter must not be used in SGeRAC A.11.20 toolkit
Oracle Clusterware Multi-node and Oracle RAC database Multi-node packages.
CLUSTER_INTERCONNECT_SUBNET requires the subnet to be configured within the SGeRAC
cluster.

reference.
• See “Operating-System Dependencies” (page 7) and “Announcements for HP-UX 11i v3”
(page 8).
• Serviceguard version A.11.20 must be installed as a prerequisite product for SGeRAC version
A.11.20. Or, if the correct version of Serviceguard is not installed on the system, but present
on the media from which SGeRAC is going to be installed, Serviceguard will be selected for
the installation as well. (See the latest version of the Serviceguard Version A.11.20 Release
Notes at the address given above for more information about Serviceguard.)
• Version A.11.20 of SGeRAC permits a maximum of 16 HP 9000 or HP Integrity servers
configured as a high availability cluster. Multiple Oracle databases on the same node are
supported.
• An SGeRAC cluster must have SGeRAC software installed on all the nodes. SGeRAC version
A.11.17 and later will enforce this homogeneity requirement at cluster creation and formation.
NOTE: Beginning with Serviceguard A.11.20 Patch PHSS_42137, to allow a rolling upgrade
from a Serviceguard only cluster with Serviceguard version A.11.19 and earlier version of
OE to a Serviceguard and SGeRAC version A.11.20 with 11.31 1109, Serviceguard allows
a mixed Serviceguard and SGeRAC nodes to co-exist. So from Serviceguard Patch
PHSS_42137 onwards, you will not see any error or warning messages related to missing
SGeRAC software on some of the nodes during cluster creation. Ensure 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.
• Requirements for Rolling Upgrade to A.11.20.
To perform a rolling upgrade to SGeRAC A.11.20, you must be running the following:
◦ HP-UX 11i v3
◦ SGeRAC A.11.19
If you are not already running A.11.19, you may be able to do a rolling upgrade to A.11.19,
and from A.11.19 to A.11.20.
IMPORTANT: You can upgrade to SGeRAC A.11.19 while using HP-UX 11i v2. But, to
upgrade to SGeRAC A.11.20, you must upgrade to HP-UX 11i v3 first.
