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 nodes when the private network or attached storage is
unavailable to one or more nodes
• Disks for database and flash recovery area — Provide storage area for creating the database (data disk)
and the flash recovery area
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 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 disks.
After you identify the appropriate disks, perform the following steps on one node.
