Appendix B. Booting a System for SysBack Installation or

Maintenance

This appendix provides the specific step-by-step instructions for booting a system

to the SysBack Installation and Maintenance menu, used to install a system from a

SysBack system backup.

The instructions for booting the system to the Installation and Maintenance menus

differ depending on whether the system is booted from a bootable tape or from a

network boot server, and also differ depending on the type of the machine to be

booted. Instructions are provided for each of the following machine types:

v Common Hardware Reference Platform (uni or multiprocessor)

v Microchannel-based RISC System/6000 (uniprocessor)

v Microchannel-based RISC System/6000 SMP (multiprocessor)

v PCI-based (RSPC) RISC System/6000 (uni or multiprocessor)

v Scalable POWERparallel (SP) Node (uniprocessor)

v Scalable POWERparallel (SP) Node (multiprocessor)

If an error occurs during a network or tape boot, a value might appear in the

system LED panel. On many PCI-based systems, the LED panel is optional but

makes troubleshooting a network boot much easier. Refer to Appendix C, “LEDS”,

on page C-1 for a detailed explanation of the LED codes used in SysBack. For LED

values that are not listed in Appendix E, refer to the AIX documentation.

There are three steps to boot a system:

1. Initiate the boot process.

2. Initiate the network boot (for systems booted from the network).

3. Complete the boot.

Initiating the boot process

The following sections describe how to begin the boot process for the different

types of systems.

Common Hardware Reference Platform (uni or

multi-processor)

The CHRP systems are actually PCI-based and the boot process is identical to other

PCI-based systems. To boot these systems, refer to the instructions in “PCI-based

(RSPC) RISC System/6000 (uni or multi-processor)” on page B-3.

Microchannel-based RISC System/6000 (uniprocessor)

You can boot a microchannel-based RISC System/6000 system in one of two ways:

from a SysBack system backup tape or from a network boot server.

Booting from a SysBack system backup tape

To boot the system using a system backup tape:

1. Insert the system backup tape in the drive.

2. Turn the system key to the SERVICE position.
