Set Up an NFS Server for Sun HPC ClusterTools Software Clients

This chapter explains how to use the ctnfssvr command to

Install Sun HPC ClusterTools NFS server software.

Enable Sun HPC ClusterTools NFS server software.

Disable Sun HPC ClusterTools NFS server software.

Remove Sun HPC ClusterTools NFS server software.

Overview

The following is a summary of the basic operations involved in installing Sun HPC ClusterTools software in an NFS client/server configuration:

Use ctnfssvr to install the non-root Sun HPC ClusterTools software packages on the NFS server and to enable the Sun HPC ClusterTools software.

Use ctgui or the CLI command ctinstall -c to install the root packages on the cluster nodes.

If you will use the NFS server as a cluster node, use ctgui or ctinstall -c to install the root packages on the NFS server as well.

Note - You can perform these operations in any order, but the Sun HPC ClusterTools software can not be activated until the NFS server is installed, enabled, and properly mounted.

See Chapter 3 for instructions on using ctgui and Chapter 4 for instructions on using ctinstall and the other CLI commands. The rest of this chapter explains how to use ctnfssvr to install the non-root packages on the NFS server.

See TABLE 5-1 for a summary of the ctnfssvr options.


Options	Description
Operations
-i	Install non-root packages. The following options can be used only with `-i`.
	`-d` Specify a non-default install from location. The default is distribution`/hpc/Product`, relative to the directory where `ctnfssvr` is invoked.
	`-s` Specify a security option for Sun CRE. The choices are `sunhpc_rhosts`, `rhosts`, `des`, and `krb5`. The default is `sunhpc_rhosts`.
	`-t` Specify a non-default install to location. The default is `/export`.
-r	Remove the non-root packages.
-D	Disable serving Sun HPC ClusterTools software clients over NFS.
-E	Enable serving Sun HPC ClusterTools software clients over NFS.
Other
-h	Command help.
-x	Turn on command debug mode.

Note - You must be logged in as superuser to run ctnfssvr.

Special Note for Activating Sun HPC ClusterTools Software in an NFS Configuration

When you want to activate Sun HPC ClusterTools software in an NFS configuration, you must ensure that the activation tool is able to locate the software mount point. You can do this in either of the following ways:

Use the activation tool under the NFS mount point on an NFS client: mount_point/*/SUNWhpc/HPC5.0/bin/Install_Utilities/bin

Or, explicitly mount the directory in which SUNWhpc is installed. For example, if SUNWhpc is installed in /export/apps, enter the following on an NFS client:

# mount server:/export/apps mount_point

Sun HPC ClusterTools software activation is described in Chapter 3 (for ctgui) and Chapter 4 (for ctact).

Installing the Non-Root Packages on an NFS Server

Install NFS Server Software


# `./ctnfssvr -i`

CODE EXAMPLE 5-1 sets up the NFS server and installs the non-root packages from the Sun HPC ClusterTools software suite. However, the NFS server has not been enabled to service Sun HPC ClusterTools software requests from the NFS clients (that is, the cluster nodes).


# `./ctnfssvr -i -E`

CODE EXAMPLE 5-2 is the same as CODE EXAMPLE 5-1, except that the -E option enables NFS services for the Sun HPC ClusterTools software clients.

Other `ctnfssvr` Examples


# `./ctnfssvr -E`

CODE EXAMPLE 5-3 enables the NFS server software after it has been installed.


# `./ctnfssvr -D`

CODE EXAMPLE 5-4 disables the NFS server software.


# `./ctnfssvr -r`

CODE EXAMPLE 5-5 removes all NFS server software. If the software is in the enabled state, -r will automatically disable it before the packages are removed.
