The present document provides the step (in detail) to create ASM diskgroups on NAS/NFS file devices.
Situations where NFS on ASM may be a reasonable option include:
- Using NFS for an ASM Quorum Failure Group, as is often done with Extended Clusters. NFS on Quorum Failure Groups with 184.108.40.206 or later, does not need, or should not use hard NFS mounts.
- Situations where reliable access to NFS service can be assured.
- When using NFS storage only for an External Redundancy Diskgroup.
- Situations where the lost of ASM file access for an extended period is not critical.
