OCR and voting disk storage configuration for external redundancy
Figure: OCR and voting disk storage configuration for external redundancy illustrates the OCR and voting disk storage options for external redundancy.
If you want to place OCR and voting disk on a clustered file system (option 1), you need to have two separate files for OCR and voting information respectively on CFS mounted on a CVM mirrored volume.
If you want to place OCR and voting disk on CVM raw volumes or on ASM disk groups that use CVM raw volumes (option 2), you need to use two CVM mirrored volumes for configuring OCR and voting disk on these volumes.
For both option 1 and option 2:
The option must be selected at the time of installing Oracle Clusterware/Grid Infrastructure.
The installer needs at least two LUNs for creating the OCR and voting disk storage.
See the Oracle RAC documentation for Oracle RAC's recommendation on the required disk space for OCR and voting disk.
