help Synopsis help [command] Description This command lists commands and capsule descriptions with syntax for each command. See Figure 3-14. Argument command Specifies the command for which detailed description is required. Figure 3-14. IPMISH help option SOL Proxy SOL Proxy is a simple telnet server. It allows a telnet client to interact with the hardware-designated serial port of a remote managed system using the LAN communication channel. See Figure 3-15.
When BIOS console redirection to serial port is enabled on the remote managed system, any application that uses the BIOS to read from or write to the system console will have its I/O redirected to the designated serial I/O port. When SOL is activated, the BMC firmware reads any data written to the serial port and transmits it to the SOL Proxy as LAN packets. SOL Proxy then forwards the data to the telnet client as TCP/IP packets.
You can use a variety of telnet clients to access SOL Proxy features. For example: • In a Windows environment, you can use a Command Prompt window as your console. However, function keys such as and will not operate correctly with this client except on systems running Windows Server 2003. • In a Windows environment, you can also use any telnet application that supports VT100 or ANSI emulation mode (such as HyperTerminal) as your console.
The Linux SysRq function is one example of an advanced debugging feature that is enabled by use of the break function. See the "BIOS Configuration" on page 25 on how to use this feature. See the "Serial Console redirection With SOL Proxy" on page 133 for more information on the SysRq feature. To enable BIOS console redirection for use with SOLProxy: • Configure the Console redirection attribute to On with Console Redirection via COM2 for Dell x9xx and xx0x.
4 Provide a password when prompted. SOL Proxy will use this combination of operating system username and password to authenticate you on the SOL Proxy Server. The specific authentication scheme will depend on the operating system configuration for the SOL Proxy Server. However, if localhost or an IP address of 127.0.0.1 is used, it is assumed that the user has login privileges to the current host, and is not prompted for a username and password.
5 After authentication, a login successful message and the SOL Proxy main menu prompt appear. You are ready to use SOL Proxy. See "SOL Proxy Main Menu" on page 83 for further instructions. SOL Proxy Main Menu After the telnet connection with SOL Proxy is successfully established, you are presented with the following choices. See Figure 3-16. Figure 3-16.
Menu option 2 allows you to enable, disable, and configure the SOL defaults, including the minimum user privilege level required for activating SOL and the communication baud-rate. Menu options 3 and 4 allow you to establish a SOL remote console session through the SOL Proxy main menu. Menu option 3 establishes a SOL session without changing the remote system’s state. This option is ideal for connecting to the Microsoft SAC/EMS or the Linux console.
Figure 3-17. Connecting to the Remote System’s BMC Configuring the SOL for the Remote Managed System Select option 2 in the main menu. NOTE: You must be connected to the managed system’s BMC before you can configure the SOL features. If SOL Proxy is not yet connected to the managed system’s BMC, you are prompted for an IP address, a username/password combination, and an IPMI encryption key. The IPMI encryption key value will be ignored if no key was set at the BMC on the target server.
The SOL configuration menu appears. According to the current SOL status, the content of the SOL configuration menu varies: • If SOL is already enabled, the current settings are displayed and you are presented with three choices. See Figure 3-18. Figure 3-18. Configuring the Serial-Over-LAN for the Remote System, Example 1 • 86 If SOL is currently disabled, the options shown in Figure 3-19 are displayed.

Configuring the Serial-Over-LAN for the Remote System, Example 2 • If SOL is enabled, two BMC settings are displayed: – The communication baud-rate between the system serial port and the BMC – The minimum BMC user privilege level required for activating console redirection SOL Proxy displays a list of valid values for each feature, as well as the current value of the feature enclosed in a pair of brackets.
Figure 3-20. SOL Settings, Example 3 Activating Console Redirection Select option 3 in the main menu. NOTE: You must be connected to the managed system’s BMC before you can configure the SOL features. If SOL Proxy is not yet connected to the managed system’s BMC, you are prompted for an IP address and a username/password combination. See "Connecting to the Remote Managed System’s BMC" on page 84 for more information. The remote managed system’s text console is redirected to your management station.
Figure 3-21. Console Redirection Example Rebooting the Managed System and Activating Console Redirection Select option 4 in the main menu. NOTE: You must be connected to the managed system’s BMC before you can configure the SOL features. If SOL Proxy is not yet connected to the managed system’s BMC, you are prompted for an IP address, a username/password combination, and an IPMI encryption key. The IPMI encryption key value will be ignored if no key was set at the BMC on the target server.
While the managed system reboots, you can enter the BIOS system setup program to view or configure BIOS settings. See Figure 3-22. NOTE: Before activating the console redirection, you must first enable the console redirection features. See "Configuring Your Managed System" on page 25 for more information. Figure 3-22. Reboot Example Getting Help Select option 5 in the main menu to display detailed descriptions for each option. See Figure 3-23.
Figure 3-23. Sample Help Screen Exit Select option 6 to end your telnet session and disconnect from SOL Proxy. Using SOL proxy in command mode By default, SOL Proxy is installed for use in the menu mode by the system. See "Configuring the SOL Proxy Configuration File" on page 93 for instructions on how to change the default settings to command mode. Commands in SOL Proxy SOL Proxy command mode is similar to the IPMI Shell interactive mode.
console Synopsis console Description This command allows users to establish an SOL session with the connected server. NOTE: BMU responds with an error message if console is used before establishing an IPMI session with connect. reboot Synopsis reboot[-force] Description This command allows you to control power configurations and establish an SOL session in one atomic operation. It is equivalent to executing the menu command of "Reboot and Activate Console Redirection". See Figure 3-24.
Configuring the SOL Proxy Configuration File Certain parameters, for IPMI Shell and SOL Proxy, must be correctly configured in the SOL Proxy Configuration file, - SOLProxy.cfg, which is located in the default installation BMC directory. The parameters and their descriptions are as follows: Comments Any line starting with a “#” is treated as a comment. For example: #The file is an example. IP Address Specifies the specific IP address used to connect to SOL Proxy.
session_timeout=30 Power-off Timeout Specifies the time in seconds before the SOL Proxy gives up polling for the managed system's power status. If the SOL Proxy issues the power off command and the system does not power off within the specified interval, the SOL Proxy returns with a message, indicating that the SOL Proxy was unable to power off the system due to the timeout interval.
Sol Loss Silent Specifies system behavior when one or more SOL packets are lost. The possible values are 0 and 1. If it is set to 0 or is absent, the system will print an error message on the screen each time an SOL packet is lost. If it is set to 1, the system will not print error messages for loss of SOL packets. For example: sol_loss_silent=0 or 1 Sol Loss Threshold Specifies number of SOL packets that can be lost before SOL deactivation.
debug Specifies if the debug data will be logged. The default is off. debug=off IPMItool IPMItool is a CLI utility that helps in configuring and managing devices using the IPMI version 1.5 and later protocol. IPMItool supports out-of-band (OOB) access (over a LAN) to a single system at a time. However, multiple IPMItool sessions can run simultaneously on the same managed system. IPMItool allows a user with user-level BMC privileges to: • Display the current power status.
To facilitate command scripting, upon successful execution, IPMItool terminates with an exit code of zero, and will output the execution results in a parsable format. If an error is encountered, the program exits with a nonzero error code and outputs the error in a parsable format. See "BMC Management Utility Error Codes" on page 113 for a complete list of possible BMC Management Utility error codes. The complete list of commands listed under delloem in Table 3-2 are supported by the IPMItool.
Command Syntax: ipmitool -I lanplus -H -U -P -k delloem lcd set mode {none}|{modelname}|{ipv4address}|{macaddress}|{sy stemname}|{servicetag}|{ipv6address}|{ambienttemp }|{systemwatt}|{userdefined}|{assettag} NOTE: The kgkey (-k option in lanplus) is a string of 20 ASCII characters. This feature is enhanced for xx1x systems to support the kgkey in hex. The option is –x followed by a 40 character hex value.
ipmitool -I lanplus -H -U -P -k delloem lcd set vkvm {active}|{inactive} • lcd set frontpanelaccess: Sets the LCD mode to view and modify, view only, or disabled.
ipmitool -I lanplus -H -U -P -k delloem powermonitor powerconsumption The system peak headroom is applicable on systems with PMBus support. The peak headroom is reported in BTU/hr or Watt. Peak Headroom (in Watts) = Input Wattage to Power Supply–Peak Power drawn by the system. For redundant power supplies, the minimum input wattage between the two power supplies is taken. This value is not displayed in modular systems.
Command Syntax: ipmitool -I lanplus -H -U -P -k delloem powermonitor powerconsumptionhistory NOTE: The new power monitoring features are not supported on IPMIsh and SOLProxy. Default Subcommand If you do not specify a subcommand, this command displays the current power status of the system. The returned values denote energy consumption, peak power (in Watts), and peak amperage (in Amperes).
Default Subcommand If you do not specify a subcommand, this command is equivalent to the sensor list command. Options for mac • list: Displays the number, MAC address, and status of all NICs. It also displays the DRAC/iDRAC MAC address. • get : Displays the MAC address and status of the specified NIC number. Default Subcommand If you do not specify a subcommand, this command is equivalent to the mac list command. Options for lan • set : Allows you to set NIC selection mode.

Using the BMC Management Utility
Known Issues and Frequently Asked Questions 4 This section discusses known issues with using the BMC Management Utility, along with frequently asked questions. Known Issues General Issues • You must assign a valid BMC user name and password before you can connect to your system's BMC using the BMC Management Utility.
IPMI Shell Issues • If you type ipmish from any directory other than the directory where the BMU is installed, you will receive a "command not found" error from MS-DOS. This is because the BMU install directory is not included in the system search path. You can execute IPMISH directly by specifying a fully-qualified path or by first navigating to the BMC directory and then executing the command. You may also manually add the BMU install directory to the execution search path.
Q: Why can’t I connect to a console using the terminal emulation software included with my Microsoft Windows operating system? A: The version of HyperTerminal included with Windows does not provide many functions required during console redirection. Either upgrade to HyperTerminal Private Edition 6.1 or later, or select any other terminal emulation software that supports full configuration of VT100 or ANSI emulation mode. Q. What is the Spanning Tree feature? A.
Q: Why do I see a connection time-out error message when I perform the Power Reset command using the IPMISH command line tool? A: The spanning-tree feature described in the previous Q&A can cause problems during power management as well. Use the solution above to help assure that power reset and other power management commands can function without network timeouts.
BMC Management Utility Error Codes 5 The following is a list of error messages for the BMC Management Utility. In case of a functional failure, an error message will be printed to stderr. The text of the error message is listed in the Message column in Table 5-1. Errors will always be printed in a parsable format such as: Error ():! The following is an example: Error(0xC1):Invalid Command! Table 5-1.

Terminal Mode Commands 6 This appendix provides information about terminal mode commands. Terminal mode allows you to directly connect to the system's Baseboard Management Controller (BMC) using a serial port connection and execute text-based commands.
• Disable the RAC serial Console if you have a DRAC 5 installed. Login to the DRAC GUI, navigate to Serial from Remote Access, and disable Enable Serial console. • Set Serial Port 1 for PowerEdge x8xx systems. This option is available in the BIOS Setup, in the Integrated Devices menu. Using Terminal Mode Use the Terminal Mode feature to perform the following tasks: • Power the server on or off. • Reset the server. • Retrieve the server's health status.
Syntax Terminal mode messages follow the general syntax below: [] 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. NOTE: Hex-ASCII commands can either use upper or lower-case letters for ASCII representations of hex digits.
Hex-ASCII Command Format Binary IPMI commands are sent and received as a series of case-insensitive hex-ASCII pairs, where each is separated from the preceding pair by a single space character. Table 6-1 lists the terminal mode requests to BMC and Table 6-2 lists the terminal mode responses from BMC. The following is an example of a binary IPMI request message: [18 00 22] Table 6-1.
Examples Hex-ASCII command example (IPMI Reset Watchdog Cmd): [18 00 22] [1C 00 22 00] Text command example: [SYS TMODE] [OK TMODE] Table 6-3. Terminal Mode Text Commands Command Switches Description SYS PWD -U -U activates a terminal mode session. USERNAME USERNAME corresponds to the ASCII text for the username. represents a printable password (up to 16 characters). If is not provided, then a Null password (all binary 0’s) is submitted.
Table 6-3. Terminal Mode Text Commands (continued) Command Switches Description SYS TMODE Used as a no-op confirm that Terminal Mode is active. The BMC returns an OK response followed by TMODE. SYS SET BOOT XX YY ZZ AA BB Sets the boot flags to direct a boot to the specified device following the next IPMI command or action initiated reset or power-on. XX…BB represent five hex-ASCII encoded bytes, which are the boot flags parameter in the Boot Option Parameters.
Table 6-3. Terminal Mode Text Commands (continued) Command SYS GET BOOTOPT XX YY ZZ Switches Description This is a text version of the IPMI Get System Boot Options command. It allows any of the boot option parameters to be retrieved. XX YY ZZ represents the hex-ASCII for the data bytes that are passed in the Get System Boot Options request. The BMC returns the data from the command in hexASCII format. XX—Parameter selector. [7]—Reserved. [6:0]—Boot option parameter selector. YY—Set Selector.
Table 6-3. Terminal Mode Text Commands (continued) Command Switches SYS SET TCFG Description Returns the Terminal Mode Configuration bytes where XX and YY represent hex-ASCII encoding for the volatile version of data bytes 1 and 2 as specified in Table 6-4, and AA BB represent hex-ASCII encoding of the non-volatile version. V:XX
Table 6-3. Terminal Mode Text Commands (continued) Command SYS HEALTH QUERY Switches Description Causes the BMC to return a high level version of the system health status in terse format. The BMC returns a string with the following format if the command is accepted. PWR:zzz H:xx T:xx V:xx PS:xx C:xx D:xx S:xx O:xx Where: PWR is system POWER state. H is overall Health. T is Temperature. V is Voltage. PS is Power Supply subsystem. C is cooling subsystem (Fans). D is Hard Drive/RAID Subsystem.
Table 6-3. Terminal Mode Text Commands (continued) Command Switches Description SYS HEALTH QUERY -V Causes the BMC to return a high level version of the system health status in multi-line verbose format. The BMC returns a string of the following format: SYS Health:xx
Table 6-3. Terminal Mode Text Commands (continued) Command Switches Description SYS IDENTIFY -ON Causes the BMC to indicate the system’s location, for example, with a blinking LED or beep for a specific period of time. XX is an optional hex-ASCII byte representing the number of seconds the BMC is to cause the system to identify itself. If XX is not provided, the BMC will indicate the system’s location only for 15 seconds. This is a text version of the optional Chassis Identify command.
Table 6-4. Terminal Mode Configuration (continued) Byte Explanation 2 [7:4]—Output newline sequence (BMC to console). Selects what characters the BMC uses as the sequence when the BMC writes a line to the console in Terminal Mode. 0h = no termination sequence. 1h = (Factory default) 2h = 3h = 4h = 5h = All other = reserved [3:0]—Input newline sequence (Console to BMC).
Escape Key Sequences 7 Console redirection uses ANSI or VT100/220 terminal emulation, which are limited to basic ASCII characters. There are no function keys, arrow keys, or control keys in this character set. However, most BIOS software requires the use of function keys and control keys for ordinary actions. Specific function keys and escape keys can be emulated by using a special key sequence, called an escape sequence, to represent a specific key.
Escape Key Sequences
Serial Port Console Redirection 8 Serial Communication For Dell PowerEdge x9xx, xx0x, and xx1x systems, serial console redirection can be accomplished using COM1 or COM2.
Serial Terminal Communication to BMC or DRAC Serial Terminal Mode allows you to directly connect to the BMC or DRAC using a serial port connection and execute text-based commands. See "Terminal Mode Commands" on page 117 for information about configuring your BMC and DRAC for Serial Terminal Communication as well as available Terminal Mode Commands.
NOTE: The unattend.txt file is automatically created after installation. [Data] EMSPort EMSBaudrate Where, EMSPort = Port used for serial communication. For example, COM1 or COM2. EMSBaudrate = Configured baud rate for communication. The minimum supported baud rate for supported Dell PowerEdge systems is 19200.
3 If the /etc/grub.conf contains a splashimage directive, you must comment it out. This sample file, using a baud rate of 19200, is an example. The following maximum baud rates are allowed for BMC serial communication and SOL: • 19200 for PowerEdge 1425SC and other PowerEdge x8xx systems. • 57600 for PowerEdge x9xx and xx0x systems without Dell Remote Access Controller 5 (DRAC 5). • 115200 for PowerEdge x9xx, and xx0x systems with DRAC 5. • 115200 for PowerEdge xx1x systems. Table 8-1.
Additional information for editing the grub.conf: 1 You may need to disable GRUB's graphical interface and use the text-based interface instead; otherwise, the GRUB screen will not be displayed in BMU console redirection. To do so, comment out the line starting with splashimage. 2 If you have multiple options in GRUB and you want all of them to start a console session through the BMU serial connection, add console= ttyS1,19200 to all options.
Table 8-2. Sample File: /etc/innitab # # inittab This file describes how the INIT process should set up # the system in a certain run-level. # # Author: Miquel van Smoorenburg,
Table 8-2. Sample File: /etc/innitab (continued) # Things to run in every runlevel. ud::once:/sbin/update # Trap CTRL-ALT-DELETE ca::ctrlaltdel:/sbin/shutdown -t3 -r now # When our UPS tells us power has failed, assume we have a few # minutes of power left. Schedule a shutdown for 2 minutes from now. # This does, of course, assume you have power installed and your # UPS is connected and working correctly.
Edit the file /etc/securetty, as follows: Add a new line, with the name of the serial tty for COM1: ttyS0 See the sample file, which shows the addition of the new line. Table 8-3.
