See the System Software Guide on the Resource CD for instructions on running the SMU from the UT. The managed system must have a CD drive.

  • Page 19: User Configuration Subtask

    User Configuration Subtask The User Configuration subtask provides a way to configure the user access to the LAN and Serial channels. Up to four users are allowed. Some of the options presented in these screens depend on how the channels have been configured; therefore, the channels should be configured before you access these settings.

  • Page 20: Edit User Configuration Screen

    Otherwise, the firmware attempts to use the first entry in the user table that it finds that allows access to the specified channel and would expect the password associated with that entry to be the one entered to gain access to the specified channel. The figure below shows the screen that is displayed when a User Name is selected and then the Edit button is clicked.

  • Page 21: Lan Channel Configuration Subtask

    The password can be from 1 to 16 ASCII characters long. The characters accepted by the SMU for usernames are the ASCII printable characters in the range 0x21 through 0x7e, except for left and right bracket characters ('[' and ']'). These characters are reserved for framing packets for terminal mode sessions.

  • Page 23 The meanings of the different privilege levels are described below: • Callback: Only commands needed to initiate a callback session are allowed. Although Dell OpenManage system management software does not support callback as a connection mechanism, it is still a valid privilege level because it defines a set of BMC commands that can be executed by a user.

The IP address is entered as a dotted notation, such as 192.168.0.2. Subnet Mask The edit box is for the host's subnet mask. The system uses this to decide if alert destinations are in the local subnet or in another subnet relative to the client console.

    Baud Rate This field sets the baud rate at which serial data is transferred by the BMC when SOL is active. The choices are Default IPMI, 9600 bps, 19.2 kbps, 38.4 kbps, 57.6 kbps, and 115.2 kbps. If Default IPMI is selected, the baud rate used is the rate currently set for BIOS serial redirection. When SOL is active, serial communication with the BMC always occurs with 8 data bits, no parity, 1 stop bit, and RTS/CTS (hardware) flow control.

    Start a Command Prompt window. Go to the directory where the file ipmish.exe is located. By default, ipmish.exe is located at the directory: C:\ProgramFiles\ Dell\OpenManage\bmcconsole. Enter IPMI Shell commands (see "IPMI Shell Command Syntax") to manage the remote system. Go to "IPMI Shell Commands" for a complete list of valid options, commands, subcommands, and arguments.

  • Page 35: Ipmi Shell Global Options

    IPMI Shell Global Options IPMI Shell has the following global options: IPMI Session Option -ip Synopsis ipmish -ip bmc_ip_address | bmc_hostname -u username -p password Description This option is used to establish a connection to a remote managed system using the LAN channel. The IP port specified in installation (default value is 623) is used unless another port has been configured.

  • Page 36: Help Command

    Options NOTE: The following options cannot be used independently. One or more IPMISH command must follow the option. -com serial_port Specifies the serial port used when establishing an IPMI session to the managed system. For a system running Windows, the management station port can be 1, 2, 3, and so on. For systems running Red Hat Linux, the management station port can be ttyS0, ttyS1, ttyS2, and so on.

    Known Issues and Frequently Asked Questions Q: Do IPMI Shell commands correspond one-to-one to IPMI commands? A: IPMI Shell provides only the most useful IPMI commands. It includes a definitive set of commands that can be used to accomplish the most common management tasks. Therefore, IPMI Shell commands may not correspond one-to-one to IPMI commands.

  • Page 65: B Using Console Redirection

    Using Console Redirection Console redirection allows you to manage a host (local) system from a client (remote) system by redirecting keyboard input and text output through a serial port. You cannot redirect graphic output. You can use console redirection for tasks such as configuring BIOS settings. You can also connect the client system to a port concentrator that can access numerous host systems using a shared modem.

  • Page 66: Configuring The Client System

    Configuring the Client System After configuring the host system, configure the ports and terminal settings for the client (remote) system. NOTE: The examples in this section assume that you have upgraded to Hilgraeve's HyperTerminal Private Edition 6.1 or later. If you are using other terminal emulation software, see the documentation for that software.

    Each terminal mode message must be preceded with the left bracket "start” character and must be ended with a right bracket “stop” character and the appropriate input new-line sequence. No input characters are accepted until the start character has been received. Terminal mode text commands are case sensitive, but hex-ASCII commands can either use upper or lower case letters for ASCII representations of hex digits.

  • Page 73: Text Command Format

    The software ID and LUN for the remote console are fixed and implied by the command. The SWID for messages to the remote console is always 47h, and the Logical Unit Number (LUN) is 00b. Instead, there is a "bridge" field that is used to identify whether the message should be routed to the BMC’s bridged message tracking or not.
