Building Disaster Recovery Serviceguard Solutions Using Metrocluster with Continuous Access for P9000 and XP A.11.00

8. In the Specify Voting Disk Location screen, select External Redundancy and specify the CFS
file system directory if you have an independent backup mechanism for the Voting Disk.
To use the internal redundancy feature of Oracle, select Normal Redundancy and specify
additional locations.
In this example, for the SFO Clusterware sub-cluster, the location is specified as:
/cfs/sfo_crs/VOTE/vote
9. Complete the remaining on-screen instructions to complete the installation.
Once the installation is complete, you must ensure that Oracle Clusterware is installed appropriately,
and that the Clusterware sub-cluster is formed. To ensure that Oracle Clusterware is installed
appropriately, verify if the /opt/crs/oracle/product/10.2.0/crs/bin/crsd.bin and
/opt/crs/oracle/product/10.2.0/crs/bin/ocssd.bin processes are running on all
nodes in the current site.
To ensure that the Oracle Clusterware sub-cluster if formed, run the olsnodes -n command. This
command lists the nodes of the Oracle Clusterware sub-cluster. In this example, this command lists
the nodes of the SFO CRS sub-cluster.
olsnodes -n
SFO_1 1
SFO_2 2
Configuring SGeRAC toolkit packages for the site Oracle clusterware sub-cluster
To configure SADTA, the Clusterware daemons must be managed through Serviceguard. As a
result, the Clusterware sub-cluster at the site must be packaged using the SGeRAC toolkit. This
configuration must be done at both sites in the Metrocluster. Also, ensure that the package service
is configured to monitor the Oracle Clusterware.
For information about configuring the Clusterware packages, see Use of Serviceguard Extension
for RAC Toolkit with Oracle RAC 10g Release 2 or later manual available at http://www.hp.com/
go/hpux-serviceguard-docs->HP Serviceguard Extension for RAC.
SGeRAC toolkit packages can be created using the Package Easy Deployment feature available
in Serviceguard Manager version B.03.10. For more details, see Using Easy Deployment in
Serviceguard and Metrocluster Environments on HP-UX 11i v3 available at http://www.hp.com/
go/ hpux-serviceguard-docs —> HP Serviceguard.
Installing and configuring Oracle Real Application Clusters (RAC)
The Oracle RAC software must be installed twice in the Metrocluster, once at every site. Also, the
RAC software must be installed in the local file system in all the nodes in a site.
To install Oracle RAC, use the Oracle Universal Installer (OUI). After installation, the installer
prompts you to create the database. Do not create the database until you install Oracle RAC at
both sites. You must create identical RAC databases only after installing RAC at both sites.
For information about installing Oracle RAC, see the documents available at the Oracle
documentation website. This section describes the high-level steps to install Oracle RAC.
To install Oracle RAC in the Metrocluster:
1. Start the Oracle Universal Installer from the temporary directory.
For example,
<Oracle Installation directory>/database/runInstaller
2. On the Specify Home Details screen, specify the local file system directory where the RAC
software is installed on the site nodes.
3. On the Specify Hardware Cluster Installation Mode screen, select Cluster Installation and select
the nodes in addition to the local node.
