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
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.

Release Notes
Read the Release Notes for all products included with this product. Portable
Document Format (.pdf) versions of the Release Notes are included on the
software disc in the
storage_foundation_cluster_file_system/release_notes directory
and on the documentation disc that came with your software.
Because product Release Notes are not installed by any packages, it is
recommended that you copy them from the disc to the /opt/VRTS/docs
directory on your system so that they are available for future reference.
Product licensing
Product keys are available on the License Key certificate. The certificate also
includes the number of product licenses purchased. A single key enables product
installation on the number and the type of systems for which you purchased the
license. A key may enable the operation of more products than specified on the
certificate, but you are legally limited to the number of product licenses
purchased.
The VRTSvlic package executes Veritas product licensing. The following
commands and their manual pages are available on the system after VRTSvlic
is installed:
vxlicinst installs a license key for a Veritas product
vxlicrep displays currently installed licenses
vxlictest retrieves features and their descriptions encoded in a license
key
If you encounter problems while licensing your product, visit the Veritas
licensing support website at
http://www.veritas.com/buy/vLicense/vLicenseHome.jhtml.
Veritas products are installed under the /opt directory on the specified host
systems. Verify that the directory /opt exists and has write permissions for
root before starting the installation procedure. Do not make /opt a VxFS file
system.

18 Installing and configuring the product
Preinstallation
Also, you can get the patches from Hewlett-Packard’s Patch Database offered
under the Maintenance and Support section of the HP Services & Support - IT
Resource Center. HP’s Patch Database provides fast, accurate searches for the
latest recommended and superseded patches available for Veritas File System or
Veritas Volume Manager.
Setting PATH and MANPATH environment variables
The software and online manual pages for the packages comprising SFCFS are
installed in several different directories. However, there are symbolic links to all
commands in the /opt/VRTS/bin directory, and symbolic links to all manual
pages in /opt/VRTS/man. To make all SFCFS commands and manual pages
accessible when you do the installation, add /opt/VRTS/bin to your PATH and
/opt/VRTS/man to your MANPATH environment variables. Command line
examples in this guide assume these environment variables are set.
To prevent conflicts with VxFS manual pages previously installed with
JFS/OnLineJFS 3.5, the VxFS 5.0 manual pages are installed in the
/opt/VRTS/vxfs5.0/man directory. The /opt/VRTS/vxfs5.0/man
directory is automatically added to /etc/MANPATH when the VxFS 5.0 package
is installed. Make sure that the /opt/VRTS/man directory or the
/opt/VRTS/vxfs5.0/man directory goes before /usr/share/man in you
MANPATH environment variable so that the latest version of the VxFS manual
pages display.
Secure communication
Establishing a secure communication between nodes is required to install and
configure a cluster. The ssh command provides a remote communication and a
greater level of security than the rsh command.
See the Veritas Storage Foundation and High Availability Solutions Getting
Started Guide.

19Installing and configuring the product
Prerequisites
Veritas Enterprise Administrator
The Veritas Enterprise Administrator (VEA) client can be installed and run on
any machine that supports the Java Runtime Environment.
VEA is required to access the graphical user interface (GUI) for Veritas Storage
Foundation. You can use the GUI to administer disks, volumes, file systems, and
database functionality on local or remote machines.
One of the following packages needs to be installed and running on the client:
■Veritas Enterprise Administrator (VRTSobgui)
This is the client package for HP-UX.
■Veritas Enterprise Administrator for Windows (windows/VRTSobgui.msi)
This is the client package for Windows.
Check the Veritas Storage Foundation Release Notes for any patch information
before you install VEA.
Requirements
The following are system recommendations for the GUI:
Alternatively, remove the file /sbin/init.d/vmsa-server.
Prerequisites
Each cluster node must be connected to the public network and each must have
a unique host name by which it can be addressed on the public network. The
local node from which you install does not have to be part of the cluster.
Provide the following information when installing the SFCFS:
■The cluster name, beginning with a letter (a-z, A-Z).
■A unique ID from 0-65535 for the cluster. Within the public subnet, a new
cluster using a duplicate cluster ID can cause existing clusters to fail.
■The Storage Foundation Cluster File System is also supported without I/O
fencing enabled. However, without I/O fencing enabled, split brain scenarios
can result in data corruption.
OS Requirements
HP-UX 512MB of memory
Windows XP, NT, ME, 2000, or
98
300MHz Pentium with at least 256MB of memory

20 Installing and configuring the product
Installing the product
■The host names of the cluster nodes.
■The device names of the network interface cards (NICs) used for the private
networks among nodes.
■Establishing communication between nodes is required to install Veritas
software from a remote system, or to install and configure a cluster. The
node from which the installation utility is run must have permissions to run
rsh (remote shell) or ssh (secure shell) utilities as root on all cluster nodes
or remote systems.
See Veritas Storage Foundation and High Availability Solutions Getting
Started Guide.
■Symantec recommends configuring the cluster with I/O fencing enabled. I/O
fencing requires shared devices to support SCSI-3 Persistent Reservations
(PR). Enabling I/O fencing prevents data corruption caused by a split brain
scenario.
The Storage Foundation Cluster File System is supported without I/O
fencing enabled. However, without I/O fencing enabled, split brain
scenarios can result in data corruption.
Installing the product
The product installer is the recommended method to license and install the
product. The installer also enables you to configure the product, verify
preinstallation requirements, and view the product’s description.
At most points during an installation, you can type b(“back”) to return to a
previous section of the installation procedure. The back feature of the
installation scripts is context-sensitive, so it returns to the beginning of a
grouped section of questions. If an installation procedure hangs, use Control–c
to stop and exit the program. There is a short delay before the script exits.
The following sample procedure is based on the installation of a Veritas Storage
Foundation Cluster File System HA cluster with two nodes: “system01” and
“system02.” If you are installing on standalone systems only, some steps are
unnecessary, and these are indicated. Default responses are enclosed by
parentheses. Press Return to accept defaults.
Note: If you have obtained a Veritas product from an electronic download site,
the single product download files do not contain the installer installation
script, so you must use the product installation script to install the product. For
example, if you download Veritas Cluster File System, use the installsfcfs
script instead of the installer script.
