In the table below
- Binaries is the shared mount points where the Oracle Home and CRS_HOME is installed.
- Datafiles includes Online Logs, Controlfile and Datafiles
- nfsvers and vers are identical on those OS platforms that has nfsvers. The ver option is an alternative to the nfsvers option. It is included for compatibility with other operating systems,

* NFS mount option “forcedirectio” is required on Solaris platforms when mounting the OCR/CRS files when using Oracle 10.1.0.4 or 10.2.0.2 or later (Oracle unpublished bug 4466428)
** AIX is only supported with NAS on AIX 5.3 TL04 and higher with Oracle 10.2.0.1 and later (NetApp)
*** NAS devices are only supported with HPUX 11.23 or higher ONLY
**** As per BUG 11812928, the ‘intr’ & ‘nointr’ are deprecated in OEL 5.6 kernels and up including Oracle Linux 6. It is harmless to still include it, but the “NFS: ignoring mount option: nointr” will appears. This message can be ingnored.
# These mount options are for Linux kernels 2.6 and above for older kernels please check Note 279393.1
Due to Unpublished bug 5856342, it is necessary to use the following init.ora parameter when using NAS with all versions of RAC on Linux (x86 & X86-64 platforms) until 10.2.0.4. This bug is fixed and included in 10.2.0.4 patchset.
