Preparing the Disks for Oracle Clusterware
This section provides information for creating the logical drives for the following disks:
• Oracle Clusterware Registry (OCR) disk — 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 Fibre
Channel storage. When you create the partitions, ensure that the cluster nodes can detect the LUNs or
logical disks that are assigned to the attached storage system.
To prepare the disks for Oracle Clusterware, identify the OCR, voting, and data and backup disks.
After you identify the appropriate disks, perform the following steps on one node.
