5.4.1 The bootinfo Command

The type of machine (platform type) being used can be determined with the

bootinfo

command. This command uses the device configuration databases to

obtain information. In addition, the

bootinfo

command uses the values which are

stored in NVRAM.

Using

bootinfo

with the

-T

option displays the platform type of the machine. There

are currently three values that the command can return. These are shown in
Table 15.

5.4.2 Creating a System Backup

This section deals with creating system backups on PCI-Based RS/6000 Systems
which will be restored on PCI-Based RS/6000 Systems. Section 5.4.5, “Creating
System Backups on Microchannel-Based RS/6000 Systems” on page 87, deals
with creating system backups on Microchannel-Based RS/6000 Systems to restore
on PCI-Based RS/6000 Systems

Creating a system backup, or mksysb, is very simple. If you were using a tape
drive, for example rmt0, you could easily create a system backup from the
command line by typing:

mksysb -i /dev/rmt

This would create a bootable image of your system which can be used to either
recreate the system or to restore files.

Alternatively, you can use SMIT to create your system image. To do this, you can
use the SMIT fastpath:

smit mksysb

This will present you with the screen shown in Figure 28 on page 84.
