Accessing the Monitor Prompt

You can reach the monitor prompt in the following ways:

• From the ISL prompt, you can boot the monitor into interactive mode

(see “Booting the vPars Monitor” on page 74).

• After shutting down all virtual partitions, you will arrive at the

monitor prompt on the console (see “Shutting Down or Rebooting the

Computer” on page 91).

• When the system monarch CPU is not owned by any partition, you

will also see the monitor prompt MON> while toggling among the

virtual consoles.

A monarch CPU exists in both non-vPars and vPars computers. After

a computer is powered-on, the monarch CPU determines what other

CPUs are conﬁgured in the computer and then launches the other

CPUs to create a multi-CPU computer. Typically, the CPU with the

lowest numbered hardware path address (hpa) is the monarch CPU.

To see the lowest numbered hardware path, on a non-vPars computer

use ioscan, or on a vPars computer use the monitor command scan.
