Methods To Reach the ok Prompt

There are several ways to reach the ok prompt, depending on the state of the system
and the means by which you are accessing the system console.
Note – These methods of reaching the ok prompt work only if the system console
has been redirected to the appropriate port. For details, see
OpenBoot Configuration Variable Settings" on page
The methods are:

Graceful shutdown

■
system controller break and console command pair
■
L1-A (Stop-A) keys or Break key
■
Manual system reset
■
A discussion of each method follows. For step-by-step instructions, see
the ok Prompt" on page
Note – As a rule, before suspending the operating system, you should back up files,
warn users of the impending shutdown, and halt the system in an orderly manner.
However, it is not always possible to take such precautions, especially if the system
is malfunctioning.
Graceful Shutdown
The preferred method of reaching the ok prompt is to shut down the operating
system by issuing an appropriate command (for example, the shutdown, init, or
uadmin command) as described in Solaris system administration documentation.
You can also use the system Power button to initiate a graceful system shutdown.
Gracefully shutting down the system prevents data loss, enables you to warn users
beforehand, and causes minimal disruption. You can usually perform a graceful
shutdown, provided the Solaris OS is running and the hardware has not experienced
serious failure.
