Reaching The Ok Prompt; Graceful Shutdown - Fujitsu SPARC Enterprise T2000 Administration Manual

When you deliberately place the system under firmware control in order to
■
execute firmware-based commands.
It is the last of these scenarios which most often concerns you as an administrator,
since there will be times when you need to reach the ok prompt. Several ways to do
this are outlined in
see "Getting to the ok Prompt" on page

Reaching 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. In order of
desirability, these are:

Graceful shutdown

■
ALOM CMT 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.
You can also perform a graceful system shutdown from the ALOM CMT command
prompt.
