OCR and voting disk storage configuration for normal redundancy
The OCR and voting disk files exist on separate cluster file systems.
Configure the storage as follows:
  • Create separate filesystems for OCR and OCR mirror.
  • Create separate filesystems for a minimum of 3 voting disks for redundancy.
  • The option Normal Redundancy must be selected at the time of installing Oracle Clusterware/Grid Infrastructure.
    Note: It is recommended that you configure atleast resource dependency for high availability of the OCR and voting disk resources.
