Introduction • MDMSview - A graphical user interface that manages all ABS and MDMS objects using a view-based approach for navigation. Views currently supported include Objects, Tasks, Requests, Reports and Domain. Chapter 6 describes the Graphical User Interface. • DCL Interface to the Database Objects - A comprehensive set of DCL commands to manage all ABS objects, compatible with the interface for MDMS media management objects. Chapter 6 describes DCL operation, with a full reference in the MDMS Reference Guide. Planning for Disaster Recovery is an important part of any datacenter operation. Chapter 7 offers guidelines on how to plan for disaster recovery with ABS. Chapter 11 offers an architectural overview of the ABS/MDMS system; you can use this to understand the internal operations of ABS and customize certain operational parameters. A troubleshooting section has been added in Chapter 12. This chapter describes how to define extended logging options, and offers solutions for some of the more common problems that can occur in an ABS environment. The appendix offers the following: • Example on configuring MDMS • Procedures for migrating from SLS/MDMS V2.x to ABS/MDMS V4.x environment • Applying Prev3 Support to use SLS as the client after the migration • Upgrading from ABS V2.x/V3.x to V4.x environment • ABS/MDMS support for fibre channel. 1-2 Introduction
2 Overview This chapter provides an overview of the various components that comprise an ABS/MDMS operational environment, and includes a simple example on how to get started with ABS. The overview discusses the following items: • ABS Operational Environment • ABS Objects • ABS Catalogs • Backup Agent • Media, Device and Management Services (MDMS) • User Interfaces • Scheduler Options • MDMS Objects • Getting Started This chapter provides an overview on the ABS and MDMS environment. See Chapter 3,Saving and Restoring Data, for detailed information on how to save and restore data using ABS. See Chapter 4,Media Management, for information about how to configure and maintain the media management environment. 2.1 ABS Operational Environment 2.2 ABS Objects ABS operational environment contains the following components: • ABS objects - ABS objects define physical locations of saved data, the criteria under which save and restore requests are performed, and the save and restore requests themselves. ABS objects are described in Section 2.2. • ABS catalogs - ABS catalogs are the components of ABS software that contain the history information about ABS save requests. Catalogs contain the records of data saved using ABS. Those records enable you to locate and restore data that was saved using ABS. ABS catalogs are described in Section 2.3. • Backup agent - A backup agent is the utility that performs the actual data movement operation. For OpenVMS systems, the backup agents are the OpenVMS BACKUP Utility and the RMU Backup Utility. For UNIX and Windows clients, the supported backup agent is gtar (tape archiver). ABS uses gtar because most UNIX and Windows systems support it. Backup agents are described in Section 2.4. The following sections summarize the objects used by ABS to save and restore data. More detailed information about ABS objects may be found in Chapter 3, Saving and Restoring Data. Overview 2–1
