Chapter 1

Installing and configuring

the product

This chapter describes how to install the Veritas Storage Foundation Cluster

File System (SFCFS). SFCFS requires several Veritas software packages to

configure a cluster and to provide messaging services. These packages include

the Veritas Cluster Server (VCS) to monitor systems and application services,

Veritas Low Latency Transport (LLT) and Veritas Group Membership and

Atomic Broadcast (GAB) for messaging and cluster membership, the Veritas

Volume Manager (VxVM) to create the shared volumes necessary for cluster file

systems, and the Veritas File System (VxFS) package.

Topics covered in this chapter include:

■Hardware overview

■Software components

■Preinstallation

■Prerequisites

■Installing the product

■Using the log files

■Verifying the configuration files

■Verifying agent configuration

■Synchronizing time on Cluster File Systems

■Configuring VCS

■VCS application failover services

10 Installing and configuring the product

Hardware overview

VxFS cluster functionality runs optimally on a Fibre Channel fabric. Fibre

Channel technology provides the fastest, most reliable, and highest bandwidth

connectivity currently available. By employing Fibre Channel technology, SFCFS

can be used in conjunction with the latest Veritas Storage Area Network (SAN)

applications to provide a complete data storage and retrieval solution.

The figure below shows the configuration of a cluster file system on a Fibre

Channel fabric with a disk array.

11Installing and configuring the product

Hardware overview

Shared storage

Shared storage can be one or more shared disks or a disk array connected either

directly to the nodes of the cluster or through a Fibre Channel Switch. Nodes can

also have non-shared or local devices on a local I/O channel. It is advisable to

have /, /usr, /var and other system partitions on local devices.

Fibre channel switch

Each node in the cluster must have a Fibre Channel I/O channel to access shared

storage devices. The primary component of the Fibre Channel fabric is the Fibre

Channel switch.

Cluster platforms

There are several hardware platforms that can function as nodes in a cluster file

system cluster.

See the Storage Foundation Cluster File System Release Notes.

Install the HP-UX 11i 64-bit operating system with the September 2004 HP-UX

11i Version 2.0 or later on each node and install a Fibre Channel host bus

adapter to allow connection to the Fibre Channel switch.

Note: For a cluster to work correctly, all nodes must have the same time. If you

are not running the Network Time Protocol (NTP) daemon, make sure the time

on all the systems comprising your cluster is synchronized.

12 Installing and configuring the product

Software components

Storage Foundation for Cluster File System is the name of the Veritas Cluster

File System product and its supporting software packages. Storage Foundation

Cluster File System HA (SFCFS HA) provides support for application failover

functionality of Veritas Cluster Server (VCS) in addition to other SFCFS features.

Packages installed with SFCFS only
