User's Guide

To support this feature, Continentalclusters must be configured with an environment that has physical
replication set up using HP StorageWorks Continuous Access P9000 or XP, HP StorageWorks
Continuous Access EVA or EMC Symmetrix Remote Data Facility (SRDF) using SLVM or Cluster
Volume Manager (CVM) or Cluster File System (CFS) for volume management. For more information
on specific Oracle RAC configurations that are supported, refer Table 2-8.
For complete installation and configuration information of Oracle and HP StorageWorks products,
refer to the Oracle RAC and HP StorageWorks manuals.

Use the following set of procedures to enable Continentalclusters recovery support for Oracle RAC
instances:
1. Configure either Continuous Access P9000 or XP, or Continuous Access EVA or EMC SRDF
for data replication between disk arrays associated with primary and recovery clusters. For
more details, see Chapter 3: “Building Disaster Recovery Serviceguard Solutions Using
Metrocluster with Continuous Access for P9000 and XP”, Chapter 4: “Building Disaster
Recovery Serviceguard Solutions Using Metrocluster with Continuous Access EVA”, or
Chapter 5: “Building Disaster Recovery Serviceguard Solutions Using Metrocluster with EMC
SRDF”.
2. Configure the database storage using one of the following software:
• Shared Logical Volume Manager (SLVM)
• Cluster Volume Manager (CVM)
• Cluster File Systems (CFS)
You need to configure the SLVM volume groups or CVM disk groups on the disk arrays to
store the Oracle database. Configure the volume groups or disk groups on both primary and
recovery clusters. Ensure that the volume groups names or disk group names on both clusters
are identical. You must also setup data replication between the disk arrays associated with
primary and recovery clusters.
Only the volume groups or disk groups configured to store the database must be configured
for replication across primary and recovery clusters. In the environment running with Oracle
Clusterware, you must configure the storage used by Oracle Clusterware to reside on disks
that are not replicated.
If you use CVM or CFS in your environment for storage infrastructure, you need to complete
the following steps at both, primary and recovery clusters.
