3.7.0 HP StorageWorks HP Scalable NAS File Serving Software provisioning guide for Oracle HP Scalable NAS (AG513-96013, October 2009)

Selecting Virtual NFS Service export options
HP Scalable NAS requires the same NFS export options as most other NAS offerings.
The four non-default required export options are:
• no_wdelay
• rw
• no_root_squash
• insecure
The use of no_root_squash is necessary for exported filesystems that will be used
for Oracle database or application installs, where the installer must run as user root
during the install process. For example, when installing Oracle RAC or a single
instance Oracle release on a filesystem that is accessed via NFS, at one point while
running runInstaller, the user must login as user root in a separate window and
run $ORACLE_HOME/root.sh. Because the root.sh script changes permissions
on files in $ORACLE_HOME that otherwise are owned by the Oracle user, you must
have the no_root_squash export option set on the exported filesystem. Otherwise,
root ownership will not be recognized and the script will fail. Some other Oracle
install scripts that run as root actually move files around within the filesystem, which
also requires root access.
Exposing the no_root_squash option can be a security risk for mixed Linux and
Windows environments. To limit the risk, either (1) specifically name the IP address
as the <client> in Exports Records for Oracle servers needing access as user root,
or (2) remove this option after an install is completed. Figure 3, below, shows two
clients, 10.10.60.13 and 10.10.60.14, specified for /u03/app/oracle.
For customers using 11g and Direct NFS, Oracle requires the insecure export
option to allow nfs requests from port numbers higher than 1024 (also called
“ disabling reserved port checking”). This option is optional for earlier Oracle releases.
Figure 3 shows the HP Scalable NAS Management Console with the filesystem for
$ORACLE_BASE configured in a single Export Group, with all the required export
options. (For more information about Export Groups, see “Configure FS Option for
Linux” in the HP Scalable NAS File Serving Software administration guide.) Note
that the default export options are on the left side of the “Options” panel and the
Oracle required non-default options are indicated on the right (no_wdelay, rw,
no_root_squash, insecure). Since no_root_squash is set for this Export
Group, we will enumerate the host addresses, in this case 10.10.60.13 and
10.10.60.14. The screen capture does not show the name of the export group,
which is “Oracle Base” in this example. This will be shown later when the Virtual
NFS Service is created.
