HP Management Blade Server - Communicating with the Management Blade

Public

How to communicate with the Management Blade Server using the Command Line Interface (CLI), the LCD Panel, or Test Shells.

Communicating with the management blade

Communication with the Management Blade, and configuration of it and the other devices in the system take place via a Command Line Interface (CLI), the LCD Panel or Test Shells.

There are three test shells implemented within the Server Management Application (SMA). There is the application level test shell that is the normal, run-time, test shell accessed and used by users and applications. There is the stand-alone test shell that resides in the boot ROM and provides basic testing of the hardware components on-board the Management Blade. There is also the manufacturing test shell. This last mode is only used at the factory.

Command line interface

The Management Blade supports a set of CLI commands. While programming a single system is much easier using the Configuration Menu GUI, writing a script of CLI commands and then executing them on each blade server can facilitate programming a group of bh7800 blade servers. The complete list of CLI can be displayed by typing (before you do this, note that there are several hundred parameters):

smc-cmd -w

You can search for commands by specifying part of the command name. This is a much better way to list commands than to list the entire set using the above command. The following returns a list of all commands that contain the specified string:

smc-cmd -e <string>

Commands are entered by typing the command at the CLI prompt.

The following command allows you to seta parameter of a command:

smc-cmd -s <param> <value>

You can getthe setting of a parameter with the following syntax:

smc-cmd -g <param>

In addition to the smc-cmd command, two other user commands are also available:

smc-ethcfg is used to configure management LAN parameters

smc-flash is used to update onboard management firmware

Configuration menu GUI

The Configuration menu provides an operator interface to the SMA. This allows you to query the status of the chassis and (with the required authority level) change the configuration of the chassis.

There are three levels of authority:

  • User: a user with the userlevel of authority can only use commands that display information.

  • Operator: a user with operatorlevel of authority can use all commands except those with the highest security level.

  • Super User: a user with super-userlevel of authority can use all commands.

Configuration upload/download

The test shell allows a connected user to transfer configuration information between the SMA and another location, whether uploading or downloading.

When a configuration upload or download is requested by the user, the user is prompted for an IP address to connect to, login details and the name of the configuration file to transfer. The file can be stored and retrieved, even remotely.

Visible information

The Configuration menu provides the user with access to the following information:

  • Alarm Event Log

  • Current state of any alarm event (without any blackouts or masking)

  • All the temperature logs

  • All the voltage logs

  • Chassis Hardware Installed Table

  • The current setting of all the configuration parameters

The Configuration menu supports the following command set. If the user attempts to invoke a command that is only available to a high-level user, then an appropriate error message is displayed and the command is ignored. Table 1 through Table 3 lists the Configuration menu command sets.

Table 2: Operator level commands

Command
Description
Activate Deferred Configuration
Implements a complete configuration that was previously ‘Uploaded’ from the user to the SMA, but was not implemented at that time because the “Defer Implementation option” was used.
The deferred configuration is stored in FLASH until this command is invoked, at which point it is removed.
Configure pager
Configures the pager service. This includes configuring the sent strings, and the configuring the users to be contacted.
Configure serial port
Configures the parameters associated with the specified RS-232 port, including baud rate, flow control (if applicable), etc.
Chassis name
Allows the chassis name to be displayed and altered.
Download configuration basic
Download configuration settings from the SMA, to the active console. This is so that settings can either be reloaded or transferred to another bh7800 via an external script.
Default slot configuration
Reset the parameters for the specified slot to the factory configured defaults, including LAN console address information.
Toggle remote modem
Displays and toggles the state of the remote modem login, between enable and disable states.
Configure LAN console
Configures the Management LAN console for the specified chassis slot number. This can be any Management LAN console in the chassis including the SMA itself.
The following parameters will need to be programmed. In the event that there previously was a blade in that slot, the default parameter values asked for is the same as the previous blade:
IP address, Gateway address, Subnet address, Host name.
Issue modem reset
If the serial port is configured as a modem, this command sends a modem reset command to the modem, which resets it. Any modem connections will be lost. The initialization results are then displayed.
Power blade down
The blade in the specified chassis slot is powered down and the alarm event is generated.
Power blade up
The blade in the specified chassis slot is powered up and the alarm event is generated.
Reset blade
The blade in the specified chassis slot is reset and the alarm event is generated.
Reset the SMA
The SMA performs a soft reset.
Set alarm threshold
Select the alarm threshold to change and adjust the threshold.
Set blackout timeout
Change the alarm blackout timeout period to a new value.
Set alarm mask
Select the alarm mask to change and either set or unset the mask.
Initiate SMA self tests
The specified SMA self-test is invoked.
Upload configuration basic
Upload configuration settings to the SMA, from the active console. You are asked to confirm overwriting of the existing configuration, and if the reconfiguration of the chassis should take place immediately or be deferred.

Table 3: Super-User Level Commands

Command
Description
Clear alarm counts
Delete all alarm counts. An event is generated to indicate this has taken place.
Clear system event log
Delete all entries in the SEL. An event is generated once the SEL has been cleared.
Clear self-test failed log
Delete all entries in the self-test log.
Configure users
Allows users to be configured for the SMA. There are three levels of user access available: User, Operator, Super User.
Download configuration full
Download a full configuration from the SMA to the active console. This differs from the operator-level commands as it allows downloading user configurations, for example.
Fibre Channel port bypass
Allows bypassing or re-enabling a Fibre Channel port on a Management LAN. An alarm event is generated if the Management LAN is reconfigured.
Fibre Channel PowerUp Config
Allows the user to change the default power up configuration of the FC Management LANs.
Fibre Channel Loop Configuration
Allows the user to change the single or dual loop configuration of the FC Management LANs.
Fibre Channel register read
Displays the values in a register on a specific Management LAN.
Fibre Channel register write
Allows the user to change the values in a register on a specific Management LAN.
Set Management Blade IP Address
Sets the IP address of the Management Blade.
Upload configuration full
Upload a full configuration to the SMA, from the active console. Different from operator level commands; allows uploading user configurations.
Upgrade SMA
