6.2 IBM Tivoli Storage Manager and BRMS tape library

management

You configure, use, and share a BRMS tape library with the IBM Tivoli Storage Manager for

OS/400 PASE server on an iSeries server as explained in the following sections.

6.2.1 IBM Tivoli Storage Manager and BRMS tape library overview

IBM Tivoli Storage Manager can use tape devices for storing client backed-up, archived, and

space-managed data and saving the IBM Tivoli Storage Manager database. These devices

must first be configured in OS/400 before they can be used by IBM Tivoli Storage Manager.

There are several different ways to use tape devices with IBM Tivoli Storage Manager:

򐂰 Manual library: This is IBM Tivoli Storage Manager using a tape library that is not in

library mode (non-BRMS).

򐂰 Automated library: This is used when using a tape library in library mode (non-BRMS).

򐂰 Manual drives: This is for all tape drives that do have the ability to be a tape library

(non-BRMS).

򐂰 USRDFN library: This type of library (used in this chapter) is defined when IBM Tivoli

Storage Manager is going to use a tape management program such as BRMS to manage

their tape inventory.

We focus only on using BRMS as IBM Tivoli Storage Manager’s tape management system in

this redbook Refer to Chapter 4 “Configuring Storage Devices” in the IBM Tivoli Storage

Manager for OS/400 PASE Administrator’s Guide, GC23-4694, for information about using

IBM Tivoli Storage Manager without BRMS.

A main benefit to using BRMS as the IBM Tivoli Storage Manager tape manager is that it

allows IBM Tivoli Storage Manager administrators to avoid dealing with checking in volumes,

managing categories, and managing scratch volumes in automated libraries on an iSeries

server. BRMS controls all of these administration tasks.

We create a user-defined (USRDFN) library in IBM Tivoli Storage Manager, which interacts

with the BRMS tape management through a set of user-written exit programs. Sample exit

programs are provided with the IBM Tivoli Storage Manager code that you can use with

BRMS without modification.

The four exits required to interface with BRMS are:

򐂰 MOUNT: This exit is used by IBM Tivoli Storage Manager to tell the media management

system to mount a specific volume.

򐂰 DISMOUNT: This exit is used by IBM Tivoli Storage Manager to tell the media

management system that a volume that is mounted is no longer needed.

򐂰 DELETION: This exit is used by IBM Tivoli Storage Manager to tell the media

management system that a volume is now empty and no longer needed by IBM Tivoli

Storage Manager.

Important: We assume that you already installed and configured BRMS on your system at

this point. See Part 3, “Backup Recovery Media Services details” on page 131, which

explains how to install and configure BRMS.
