Hints and Tips 

bootinfo -p

, you will get different results for PReP and CHRP/RPA machines. 

The result of 

bootinfo -T

 is always rspc for every PCI-based machine.

The results of 

bootinfo

 with the 

-p

 option are shown in Table 40.

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/rmt0

This would create a bootable image of your system that can be used to either 
re-create 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

You can restore your mksysb by booting from the tape that you have created 
and following the instructions that are displayed. To boot from the tape, you 
have to press F1 (or 1 on an ASCII terminal) during the firmware boot, and 
select the tape device to boot from. Alternatively, you can place the tape drive 
as the first device in the customized boot list so that the tape will 
automatically boot when the machine is powered-on or rebooted.

Platform

Description

chrp

CHRP-compliant PCI-based RS/6000 machines

rspc

PReP-compliant PCI-based RS/6000 machines

rs6k

Micro Channel-based RS/6000 machines

Creating a system backup with the 

mksysb

 command only saves data in the 

rootvg volume group. If you want to also save data from a non-root volume 
group you have to use the 

savevg

 command or the SMIT fastpath:

# smit savevg
