Use the start command to turn on full power to the remote host server.

To issue the start command:

 

  • From the server SP CLI, type:

start /SYS

  • From CMM CLI for a blade server with a single dedicated SP, type:

start /CH/BLn/SYS

  • From CMM CLI for a blade server with two dedicated SPs, type:

start /CH/BLn/NODEn/SYS

stop

Use the stop command to shut down the OS gracefully prior to powering off the host server.

To issue the stop command:

 

 

  • From the server SP CLI:

stop /SYS

 

  • Form the CMM CLI for a blade server with a single dedicated SP:

Command Syntax Example

start

 

Use the start command to turn on full power to the remote chassis.

To issue the start command to the remote chassis from the CMM CLI, type

 

 

 

start /CH

stop

Use the stop command to shut down the power on the chassis and its components gracefully.

To issue the stop command to the remote chassis from the CMM CLI, type:

 

 

 

stop /CH

stop -force

 

Use the stop -force command to immediately turn off the power to the chassis and its components.

To issue the stop -force command to the remote chassis from the CMM CLI, type:

 

 

 

 

stop -force /CH

Control BIOS boot device order


Before You Begin



Note - The Host Control BIOS boot device feature is supported on x86 system SPs. This feature is not supported on the CMM or on SPARC system SPs. For information about ILOM Host Control boot options on SPARC systems, consult the online ILOM Supplement guide or platform Administration guide provided for that system.


Follow the steps in the following procedure to override the BIOS boot device setting from ILOM by using the Host Control features.


procedure icon  Configure BIOS Host Boot Device Override

1. Log in to the ILOM SP CLI.

2. Use the cd and show commands to navigate to the host system.

For example:


->cd /HOST
/HOST
 
->show
 
/HOST
   Targets:
       diag
 
   Properties:
       boot_device = default
       generate_host_nmi = (Cannot show property)
 
   Commands:
       cd
       set
       show

3. To set the host boot device for the next time the system is powered on, type:

->set boot_device=value

Possible values are:

View and set Host Console properties

Start Host Console and view Console History or Bootlog History


Before You Begin


procedure icon  View and Configure Host Console Properties

1. Log in to the ILOM SP CLI.

2. Use the cd and ls commands to navigate to the host console properties.

For example:


-> cd /HOST/console
/HOST/console
 
-> ls
 
 /HOST/console
    Targets:
        history
 
    Properties:
        escapechars = #.
        line_count = 0
        pause_count = 0
        start_from = end
 
    Commands:
        cd
        show
        start
        stop



Note - Each time an spsh session is started, it initializes these properties to their default values: line_count = 0, pause_count = 0, start_from = end. The values for these properties are valid only for the length of that particular spsh session.


3. Use the help command to view descriptions about the Host Control proeprties.

For example:


-> help escapechars
    Properties:
        escapechars : set escape chars using the console connection
        escapechars : User role required for set = a
 
-> help line_count
    Properties:
        line_count : total number of lines to display
        line_count : Possible values = 0-2048 where 0 means no limit
        line_count : User role required for set = c
 
-> help pause_count
    Properties:
        pause_count : number of lines to display before each pause
        pause_count : Possible values = 0-2048 where 0 means no limit
        pause_count : User role required for set = c
 
-> help start_from
    Properties:
        start_from : from which end of the available history to list
        start_from : Possible values = beginning,end
        start_from : User role required for set = c 

4. Use the set command to configure the Host Console properties.

For example:

-> set line_count=value

Where value can range from 1 to 2048 lines.

-> set pause_count=value

Where value can range from 1 to any valid integer or for infinite number of lines. The default is not to pause.

-> set start_from=value

Where the value can equal end or beginning. The end value is the last line (most recent) in the buffer (the default). The beginning value is the first line in the buffer.

-> set escapechars=value

Where the value is limited to two characters. The default value is #. (Hash-Period).



Note - The /SP/console escapechars property enables you to specify an escape character sequence to use when switching from a system console session back to ILOM. Changing the escape character does not take effect in a currently active console session.



procedure icon  Start Host Console and Display Console History and Bootlog

1. Log in to the ILOM SP CLI.

2. Set the Host Console display properties, see View and Configure Host Console Properties.



Note - As of ILOM 3.0.12, Host Console properties (line_count, pause_count and start_from) are no longer persistent across all sessions. The values for these properties are valid only for the length of that particular spsh session.


3. To start the host console, type:

->start /SP/console

4. To display the Console History, type:

-> show /SP/console/history

The Console History buffer is a circular buffer that can contain up to 1 Mbyte of information. The buffer captures all POST and boot information as well as any OS information that is controlled through the Host Console.

5. To display the Bootlog type:

->show /SP/console/bootlog

The Bootlog tracks the systems’s start-up progress and logs any problems that might occur.
