IBM Tivoli Storage Resource Manager: A Practical Introduction

Chapter 7. Protecting and maintaining Tivoli Storage Resource Manager 387

7.4 Restore procedures

Figure 7-5 Tivoli Storage Resource Manager restore procedures

We describe now the procedures we have used to recover from:

򐂰 A loss of major Agent files

򐂰 A loss of major Manager files

򐂰 A loss of the Tivoli Storage Resource Manager database

7.4.1 Restore Agent files

In this restore procedure, we have:

򐂰 Stopped the Agent

򐂰 Deleted some files including the Agent executable and configuration file

򐂰 Tried to start the Agent, which failed

򐂰 Restored all of the deleted files

򐂰 Successfully started the Agent

You can see in Example 7-18, all the steps executed to destroy and recover the Agent files.

From the Tivoli Storage Resource Manager: Administrative GUI we checked to ensure that

the Agent had started successfully (

IBM Tivoli SRM -> Administrative Services -> Agents),

right-click SUSE82-1 and chose Check. Figure 7-5 shows that the Agent on SUSE82-1 did

start.

7.4.2 IBM Tivoli Storage Resource Manager Server files

Since our Tivoli Storage Resource Manager Server system also has an Agent running on it,

and the Server and Agent files are stored in the same directory structure, in this restore test

we will be recovering both the Server and Agent.

The restore procedure has the following steps:

1. Stop the Tivoli Storage Resource Manager Server and Agent.

2. Delete Tivoli Storage Resource Manager directories.

3. Try to start the Server - fails.

4. Restore all deleted directories.

5. Successfully start the Tivoli Storage Resource Manager Server and Agent.

Example 7-19 shows the Server and Agent being stopped, the files being deleted, and the

Server and Agent failing to start.

Example 7-19 Stop server and Agent and delete commands

C:\Program Files\Tivoli\TSRM>net stop "IBM Tivoli SRM Server"

The IBM Tivoli SRM Server service is stopping.

The IBM Tivoli SRM Server service was stopped successfully.
