HP Windows Server 2008 R2 Administrator's Manual page 16

EMS consists of components that are standard features of Windows Server 2008 and Windows
Server 2008 R2, and to which console redirection functionality has been added. EMS also includes
the Special Administration Console (SAC), which is unique to it. You access this console from a
headless system using terminal emulation software such as telnet and PuTTY.
When SAC is active, it displays the SAC prompt (SAC>). SAC provides the following commands
you can use to perform a number of management tasks that help return the system to a normally
functioning state:
ch
cmd
crashdump
D
F
I
KPID
LPID
lock
MPID MB-allow
P
RPID
reg_add
restart
shutdown
T
16 Special Administration Console
Lists all channels.
Creates Windows command-prompt channels. To use a command-prompt
channel, you must provide valid login credentials. You must log in to each
command-prompt instance. Press ESC+TAB to switch back and forth between
the command prompt channels and SAC. If a command prompt channel
becomes unresponsive, use the K (end) command to close it. You can then
open another command-prompt channel.
Manually generates a stop error message and forces a memory dump file
to be created. A stop error is a serious error that affects the operating system
and that could place data at risk. The operating system generates an obvious
message, a screen with the stop error, rather than continuing on and possibly
corrupting data. Also called a fatal system error.
Dumps the kernel log.
Switches between showing processes only or processes and threads in output
from the t-list command.
Sets or views the IP address of the server. If no parameters are passed, this
command lists IP information. You can display or set the IP address, subnet
mask, and gateway of a given network interface device by providing the
network number, IP address, and subnet information. To do so, use the
following format:
I network# IPaddress subnet
Ends the given process. PID is the process identification number you specify.
Lowers the priority of a process (and any associated child processes) to the
lowest possible level.
Restricts access to EMS command-prompt channels.
Limits the memory usage of a process (and any associated child processes)
to a specified number of megabytes. MB is the number of megabytes you
specify.
Switches paging on and off for the t command output.
Raises the priority of a process and associated child processes.
Allows registry edits from the SAC.
Restarts the server.
Shuts down the server. Do not use this command unless you can be physically
present at the computer when you are ready to restart it.
Lists the processes and threads that are currently running.
