Chapter 1 XSCF Overview

1-9

The user can power on and off the server by using XSCF as follows:

Power on/off the server or a domain

The user can turn on, turn off, or reset the server by using the XSCF Shell
command from a remote terminal, which is connected to XSCF over a LAN or
serial connection. When the user instructs power off, the OS is automatically shut
down, and then power will be turned off.

Cancelling power on when an error is detected

If a system abnormality occurs, the OS is automatically shut down, and the
subsequent power on will not be started. This can minimize damage to the
system.

OS startup control for power failure

XSCF performs the operations below if a power failure that causes the system to
turn off occurs:

When a power failure occurs:

XSCF performs emergency power off when the power failure occurs. In a model
connected to a UPS, any running domains may also be shut down automatically.
For a momentary power failure, XSCF may allow the system to continue working
without any shutting down.

When power is restored:

The system can be set up such that XSCF automatically turns on the power to the
server, then starts up the domains, relieving the system administrator of extra
work.

Note –

For details on operation settings for a power failure, see
