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
“Shutdown Wait Time Administration” on page 4-19
