Integrating HP Data Protector 6.1 with SAN Virtualization Services Platform

2
Abstract
This document shows how to perform a Zero Downtime Backup (ZDB) integrated with the SAN
Virtualization Services Platform (SVSP). To do this, we’ll be using the Virtual Service Manager
(VSM) Command Line Interface (CLI) and the accompanying pre- and post-exec scripts. Please
note that no typical DP ZDB agents are involved in this operation.
The SVSP version mentioned and tested here is 2.1.
Limitations
• Instant Recovery is not supported until the SVSP is fully integrated in Data Protector.
• There is a security issue due to the unencrypted password used in the script for the
connection to the Virtual Services Manager (VSM).
• Although the VSM CLI also supports Unix, this solution is a Windows only solution. It
should be possible to adapt it in a Unix environment but that’s beyond the scope of this
document. For further help please refer to the HP StorageWorks SAN Virtualization
Services Manager command line interface user guide.
Introduction
In order to do a Zero Downtime Backup while utilizing the SVSP functionality, a specific
configuration is required. In this document we’ll describe this configuration and use the SVSP
features by using pre-exec and post-exec scripts.
The ZDB Integrated with SVSP section describes the necessary steps to perform a Zero-Downtime
Backup while using the VSM.
The Appendix A section contains the scripts used, as well as a typical session output.
The Appendix B section contains detailed information on creating users and virtual disks with the
VSM GUI.
For more information on the VSM CLI, please read the HP StorageWorks SAN Virtualization
Services Manager command line interface user guide.
Concepts
The following figure shows a sample SAN topology diagram and describes the process of a
typical Zero Downtime Backup in an SVSP environment. Initially we need to add two Virtual
Services Managers and two Data Path Modules per SVSP domain.
