Preface

Data migration service (DMS) is a block-level, online and offline feature

introduced in the iSR6200 Intelligent Storage Router (iSR6200) data transport

device. The SANsurfer iSCSI/FC Router Manager utility provides this licensed

feature to simplify data migration jobs for almost zero downtime, while providing

protection against common user errors.

Intended Audience

This guide is intended for end users responsible for administration of data

migration services using the iSR6200 Intelligent Storage Router. It is assumed

that the user has a basic knowledge of managing SANs and SAN storage.

What’s in This Guide

This preface provides a general overview of DMS and the SANsurfer iSCSI/FC

Router Manager utility, and covers the intended audience, related materials,

document conventions, and contact information for technical support.

The remainder of this guide is organized into the following chapters and

appendices:

 Chapter 1 Introduction lists the DMS and SANsurfer iSCSI/FC Router

Manager features.

 Chapter 2 Getting Started describes the direct attached, fabric, and

multipath configurations, lists the supported fabric and array types, and

describes hardware and software setup.

 Chapter 3 Data Migration Objects describes the primary items that compose

DMS.

 Chapter 4 Data Migration Licenses describes the two types of migration

licenses and provides instructions for license key installation.

 Chapter 5 Performing Data Migration provides information on the data

migration service licensed features that you can view and configure using

SANsurfer iSCSI/FC Router Manager, the graphical user interface (GUI).

 Chapter 6 Command Line Interface provides information on using the

command line interface (CLI) for data migration services. It defines the guest

account and the user sessions: admin and miguser. In addition, for each

command, it provides a description, the required session type, and an

example.

 Chapter 7 Performance and Best Practices describes the factors affecting

DMS performance and offers suggestions for obtaining maximum

performance, provides recommendations for high availability and redundant

configurations, guidelines for choosing DMS options, and a few general

precautions for DMS usage.

 Chapter 8 Restrictions details the restrictions that apply to the DMS when

reconfiguring logical unit numbers (LUNs) on a storage array and removing

an array after completing data migration jobs.

 Appendix A Configuring the Data Path Through iSR6200 for Online Data

Migration provides the information you need to configure several types of

host multipathing software on Windows

®

, Linux

®

, HP-UX, IBM

®

AIX,

VMware

®

ESX, and Solaris

®

operating systems.

 Appendix B Simple Network Management Protocol provides reference

material for the simple network management protocol (SNMP), which you

can use to manage the iSR6200 router using a third-party SNMP

management application.

 Appendix C Troubleshooting lists some problems that may occur with DMS

and offers a possible reason or solution for each.

Following the appendices are a glossary of terms and acronyms used, and an

index to help you quickly find the information you need.

What’s in the Help System

Supplementing this user’s guide is the SANsurfer iSCSI/FC Router Manager help

system, which provides procedural topics for the following:

 Managing the Router provides procedures that walk you through some

common system management tasks performed using SANsurfer Router

Manager.

 Using the Wizards describes the wizard dialog boxes that walk you through

various router configuration procedures.

 Configuring CHAP describes the challenge handshake authentication

protocol (CHAP) and provides the procedures for configuring CHAP using

SANsurfer Router Manager.

 Data Migration Service provides much the same information as this guide’s

5 Performing Data Migration chapter.
