Administrator's Guide

1 Overview
The information in this README applies to the following SG SMS Version A.04.00 bundles that
include the Veritas Storage Foundation™ 5.1 SP1 Cluster File System (CFS) and Cluster Volume
Manager (CVM) by Symantec:
• T2777EB bundle — A.04.00.00 HP Serviceguard Cluster File System
• T8687EB bundle — A.04.00.00 HP HA-OE with Serviceguard Cluster File System
• T8697EB bundle — A.04.00.00 HP DC-OE with Serviceguard Cluster File System
SG SMS bundles that include the Veritas Storage Foundation Cluster File System (CFS) allow
clustered servers running HP-UX 11i to mount and use the same file system simultaneously, as if all
applications using the file system are running on the same server. SG SMS bundles that include
CFS also include the Veritas Storage Foundation Cluster Volume Manager (CVM). CVM makes
logical volumes and raw device applications accessible throughout a cluster.
The HP-UX version of the Veritas Storage Foundation™ 5.1 SP1 Cluster File System Administrator's
Guide applies to CFS as part of a stand-alone Veritas Storage Foundation installation on HP-UX
11i v3. When CFS is included in a SG SMS bundle, there are some aspects of the Veritas Storage
Foundation™ 5.1 SP1 Cluster File System Administrator's Guide that are not applicable. The
purpose of this README is to point out these differences.
The Veritas Storage Foundation™ 5.1 SP1 Cluster File System Administrator's Guide is published
on the HP Business Support Center (BSC) web site at: www.hp.com/go/hpux-serviceguard-docs→
HP Serviceguard Storage Management Suite A.04.xx
SG SMS Bundles Do Not Include VCS
As SG SMS components, CFS and CVM are integrated with HP Serviceguard to form a highly
available clustered computing environment. SG SMS bundles that include CFS and CVM do not
include the Veritas™ Cluster Server by Symantec (VCS). VCS functions that are required in a SG
SMS environment are performed by Serviceguard. When you consult the Veritas Storage
Foundation™ 5.1 SP1 Cluster File System Administrator's Guide for information on the CFS and
CVM included in a SG SMS bundle, substitute Serviceguard for VCS.
Supported Features
For information on SG SMS bundle features, options and applications, see the HP Serviceguard

HP Business Support Center (BSC) web site at: www.hp.com/go/hpux-serviceguard-docs → HP

Unsupported Features
Functionality that is documented as unsupported may not be expressly prevented from operating
on CFS, but the actual behavior is indeterminate. HP does not advise using unsupported functionality
on CFS, or to alternately mount file systems with unsupported features as local and cluster mounts.
