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).
Preface
What’s in the Help System
xvi ISR654608-00 C
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.
