sys-suspend(1) User Commands sys-suspend(1)NAMEsys-suspend - suspend or shutdown the system and power off
SYNOPSIS
/usr/bin/sys-suspend [-fnxh][-d displayname]
DESCRIPTIONsys-suspend provides options to suspend or shutdown the whole system.
A system can be suspended to conserve power or to prepare the system
for transport. The suspend should not be used when performing any hard‐
ware reconfiguration or replacement.
In case of suspend, the current system state is preserved either by
keeping memory powered (Suspend to RAM), or by saving the state to non-
volatile storage (Suspend to Disk) until a resume operation is per‐
formed by power on or a wake-up event.
On a resume in the windows environment, the system brings up lockscreen
to ensure that only the authorized person has access to the system. In
a non-windows environment, the user is prompted for password.
It is possible that when devices or processes are performing critical
or time sensitive operations (such as real time operations) the system
fails to suspend. When this occurs, the system remains in its current
running state. Messages reporting the failure are displayed on the con‐
sole or system log. Once the system is successfully suspended, the
resume operation always succeed barring external influences such as
hardware reconfiguration or the like.
In case of shutdown, the system responds as if poweroff(1M) was per‐
formed.
This command enforces the solaris.system.power.suspend. authorizations.
On a default install these are associated with the console user. Other
users need to include these authorizations or include the Suspend pro‐
file.
OPTIONS

-d displayname Connect to the X server specified by displayname.
-f Force suspend. Causes a poweroff(1M) to occur if the suspend
fails. System state are not be saved, and a normal boot follows.
-h Change the default from suspend to shutdown.
-n Do not display messages or request user intervention.
-x Disable lockscreen. This flag disables the execution of
lockscreen at resume time.
