Configuring Network and Storage for Oracle RAC Database 43
Preparing the Disks for Oracle Clusterware,
Database, and Backup
This section provides information for creating the logical drives for the
following disks:
• Oracle Cluster Registry disk (OCR) — Contains the cluster configuration
information
•
Voting disk — Provides arbitration between the cluster nodes when the
private network or attached storage is unavailable to one or more nodes
•
Data and backup disks — Provide storage areas for creating the database
(data disk) and saving the backup and log data (backup disk)
During the cluster configuration described in this document, you will create
partitions on your shared storage. When you create the partitions, ensure that
the cluster nodes can detect the LUNs or logical disks that are created in the
attached storage system.
To prepare the disks for Oracle Clusterware, identify the OCR, voting, data
and flash recovery area disks. After you identify the appropriate disks, perform
the following steps on node 1:
