Upgrading to HP Serviceguard 11.17 with Cluster Volume Manager/Cluster File Systems, December 2005

Abstract
HP Serviceguard A.11.17 tightly integrates with technology from Symantec to enable Cluster File
Systems (CFS). Seven Serviceguard Storage Management bundles, which include Serviceguard and
VERITAS software corresponding to different degrees of capability, are available. Network
requirements for some of these configurations are somewhat different than with previous versions of
Serviceguard. Several new cluster and package configuration options are available, and new
commands are introduced to enable management of the new capabilities. When the selected new
configuration radically differs from existing one, such as when moving data from raw volumes to file
systems, the data must be migrated. This paper explores the considerations in upgrading to these
environments and provides guidelines for recommended solutions.
Overview
When upgrading to Serviceguard A.11.17 and VERITAS Storage Foundation 4.1, there are multiple
areas in which changes might be appropriate. This document addresses each of the following areas
of interest:
• Packaging and installation considerations
• Networking considerations
• Serviceguard/VERITAS interoperability considerations
• New Serviceguard commands
• VERITAS storage considerations
• Serviceguard configuration considerations
• Data migration to Cluster Volume Manager (CVM)/CFS
• Other considerations
• Upgrade roadmap
This document is intended to give an overview of the upgrade process and provide guidance for
selecting from among the recommended solutions, but it does not provide all the necessary details of
the involved processes. Many other documents offer detailed explanations of these processes.
References to these documents appear throughout the paper, and a comprehensive list is included at
the end.
At the time of the initial release, Serviceguard A.11.17 is only available as part of Serviceguard
Storage Management bundles (described in the next section). Application Release (AR) and
Operating Environment (OE) releases that include Serviceguard A.11.17 are expected to be
available in late 2005. The following sections include material related to non-bundle installations of
Serviceguard to assist with future upgrade planning.
Packaging and installation considerations
In addition to the traditional packaging of Serviceguard as a stand-alone product, part of AR, or part
of the Mission Critical Operating Environment (MCOE), Serviceguard Storage Management Suite
software bundles are available. These include Serviceguard, VERITAS Storage Foundation 4.1, and
additional products that provide enhanced storage management and database integration
capabilities. Each of these bundles is designed to provide a comprehensive set of software tools
suited to a particular application environment.
