* 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required on Solaris platforms when mounting the OCR/CRS files when using Oracle 10.1.0.4 or 10.2.0.2 or later (Oracle unpublished bug 4466428) 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 

**** These mount options are for Linux kernels 2.6 and above for older kernels

Note that,dDue to Unpublished bug 5856342, it is necessary to use the following pfile/spfile initialization parameter when using NAS with all versions of RAC on Linux (x86 & X86-64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.
The parameter is,
filesystemio_options = DIRECTIO
