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.

Table 15. bootinfo -T

Platform Description

rspc PCI-based RS/6000 machines

rs6k_smp SMP-based RS/6000 machines

rs6k Microchannel-based RS/6000 machines

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.
