Preface
This manual describes the functions and use of the following program products:
• Hitachi Dynamic Link Manager
Intended Readers
This manual is intended for system administrators who use Hitachi Dynamic Link
Manager (HDLM) to operate and manage storage systems. The readers of this manual
must have a basic knowledge of the following areas:
• Linux and its management functionality
• Storage system management functionality
• Cluster software functionality
• Volume management software functionality
Organization of This Manual
This manual is organized as follows:
1. Overview of HDLM
Chapter 1 gives an overview of HDLM, and describes its features.
2. HDLM Functions
Chapter 2 describes management targets and the system configuration of HDLM,
and the basic terms and functions for HDLM.
3. Creating an HDLM Environment
Chapter 3 describes the procedures for building an HDLM environment
(including installing and setting up HDLM), and describes for canceling the
settings.
4. HDLM Operation
Chapter 4 describes how to use HDLM by using both the HDLM commands, and
how to manually start and stop the HDLM manager. This chapter also describes
how to configure an environment to properly operate HDLM, such as changing
the HDLM management-target devices that connect paths or replacing the
hardware that makes up a path.
5. Troubleshooting
Chapter 5 explains how to troubleshoot a path error, HDLM failure, or any other
ii
problems that you might encounter.
6. Command Reference
Chapter 6 describes all the HDLM commands.
7. Utility Reference
Chapter 7 describes the HDLM utilities.
8. Messages
Chapter 8 provides information for all the possible messages that could be output
by HDLM. It also lists and explains the HDLM messages and shows the actions
to be taken in response to each message.
A. Notes on Linux Commands and Files
Appendix A gives notes on Linux commands and files.
B. Troubleshooting Products That Use the Weak-Modules Script
Appendix B explains how to deal with errors that are caused by installing or
uninstalling products that use the weak-modules script.
