160 Implementing IBM Tape in i5/OS
The control group *Bkugrp saves the non-system portion of the i5/OS system, such as
database libraries, documents, and folders, as well as the Integrated File System (IFS).
For more information about IFS, refer to Chapter 3, “Overview of the IBM System i platform”
on page 83.
The control group
*System is meant for backup of the entire i5/OS system. For saving the
entire system, i5/OS must be in a restricted state, and the backup must be done from the
For saving database libraries, objects, and combinations of them, you have to define other
control groups. In 6.2, “Saving and restoring a database library” on page 160, we describe
how to define a Control Group (Backup policy in iSeries Navigator).
Using BRMS reports
Normally, you can display which objects are saved and where they are saved through the
BRMS/400 displays. You can also use the BRMS/400 displays to assist in the restore.
However, in case of system failure, you have to restore data backed up by BRMS to another
system or to a newly installed i5/OS in your system. For this, you use the
, which instructs you how to restore the entire system saved by BRMS to
another System i partition, or newly installed i5/OS. Therefore you should maintain an
up-to-date BRMS Recovery Analysis report and have it always available in printed format.
Restoring data by using BRMS
Part of the BRMS tasks includes restoring saved data and retrieving archived data. Restore of
the entire system should be tested in advance to make sure that it works without problems in
case the production System i fails.
6.2 Saving and restoring a database library
In this example, we back up an i5/OS database library to a data cartridge in a Tape library. For
this, we use the BRMS Graphical User Interface (GUI) available in iSeries Navigator. Backup
in our example consists of the following activities:
Create a media pool and add a data cartridge to it
Create a backup policy
Run the backup policy — save the database library
Restore the database library
Next we describe the listed activities for backup and restore of the i5/OS library
Creating a media pool and adding a data cartridge to it
Use the following steps to perform this activity:
1. Install iSeries Navigator on your PC, launch it, and connect to the System i partition as
described in 5.1, “Basic setup” on page 108.
2. In iSeries Navigator, expand the IP address or host name of the System i partition, expand
Backup Recovery and Media Services, expand Media, and click Media pools. A list of
media pools is displayed in the iSeries navigator right panel, as shown in Figure 6-1.
Note: Media class is referred to as media pool in BRMS GUI.

3. BRMS comes with default media pools such as Ultrium4, Ultrium3, and Fmt3582a1.
To create a new media pool based on cartridge density and other properties of an existing
media pool, right-click the media pool, and select New Based on from the pull-down
menu, as shown in Figure 6-2.

4. This presents the wizard, New Media Pool Based on... In the wizard, specify the name,
description, and cartridge density of the new media pool, as shown in Figure 6-3. Click

5. After refreshing the iSeries navigator view, a new media pool shows in the list, as can be
seen in Figure 6-4.

6. To add media to a created media pool, right-click it and select Add Media from the
pull-down menu that pops up. This is shown in Figure 6-5.

7. This presents the Add Media wizard. On the wizard click Next. On the next wizard window,
select a tape library from which you want to add media, as in Figure 6-6. Click Next.
