Preparing the Disks for Oracle Clusterware

This section provides information for creating the logical drives for the following disks:

• 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 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.
