NFS Toolkit for Linux is a software product for
HP high availability cluster system. It works as a subsystem under
ServiceGuard-Linux core software and will be invoked by ServiceGuard
to provide functions for starting, stopping, and monitoring a Network
File System (NFS) package in a cluster. This toolkit consists of
Linux shell (bash version 2.0 or above) scripts and a binary executable
code.
This NFS toolkit is designed specifically as a subsystem for
the package control script, which is part of ServiceGuard core software
to run packages in a cluster. It will provide all necessary functions
to control and monitor the NFS packages. One of the scripts, HA
NFS Script, is designed as a template that is provided for cluster
users to copy and assign variable values for their own cluster packages
they plan to provide for their NFS clients.

TheNFS Toolkit works together with ServiceGuard-Linux. The
user never needs to invoke the toolkit (except for testing). In
fact, the ServiceGuard package manager will invoke an entry in the
Package Control Script with a “start” or “stop” parameter.
(The ServiceGuard users manual, Managing ServiceGuard
on Linux, describes detail information about the Pakage
Control Script.) One of the functions in the interface script invokes
the HA NFS Script with the “start” or “stop” parameter.
The flow of the operation is as follows:
