ledmon(8) Intel(R) Enclosure LED Monitor Service ledmon(8) NAME
ledmon - Intel(R) LED monitor service for storage enclosures. SYNOPSIS
ledmon [OPTIONS] DESCRIPTION
The ledmon application is a daemon process used to monitor a state of software RAID devices (md only) or a state of block devices. The state is visualizing on LEDs associated to each slot in an enclosure or a drive bay. There are two types of system: 2-LEDs system (Activity LED, Status LED) and 3-LEDs system (Activity LED, Locate LED, Fail LED). This application has the highest priority when accessing the LEDs. The ledmon application uses SGPIO and SES-2 protocol to control LEDs. The program implements IBPI patterns of SFF-8489 specification for SGPIO. Please note some enclosures do not stick close to SFF-8489 specification. It might happen that enclosure processor will accept IBPI pattern but it will blink LEDs not according to SFF-8489 specification or it has limited number of patterns supported. LED management (AHCI) and SAF-TE protocols are not supported. There's no method provided to specify which RAID volume should be monitored and which not. The ledmon application monitors all RAID devices and visualizes their state. The ledmon application has been verified to work with Intel(R) storage controllers (i.e. Intel(R) AHCI controller). The application might work with storage controllers of other vendors (especially SAS/SCSI controllers). However storage controllers of other vendors have not been tested. The ledmon application is part of Intel(R) Enclosure LED Utilities. Only single instance of the application is allowed. OPTIONS
-c or --config=path Sets a path to local configuration file. If this option is specified the global configuration file and user configuration file has no effect. -l or --log=path Sets a path to local log file. If this option is specified the global log file /var/log/ledmon.log is not used. -t or --interval=seconds Sets time interval between scans of sysfs. The value is given in seconds. The minimum is 5 seconds the maximum is not specified. --quiet or --error or --warning or --info or --debug or --all Verbose level - 'quiet' means no logging at all and 'all' means to log everything. The levels are given in order. If user specifies more then one verbose option the last option comes into effect. -h or --help Prints this text out and exits. -v or --version Displays version of ledmon and information about the license and exits. FILES
/var/log/ledmon.log Global log file, used by ledmon application. To force logging to user defined file use -l option switch. ~/.ledctl User configuration file, shared between ledmon and all ledctl application instances. /etc/ledcfg.conf Global configuration file, shared between ledmon and all ledctl application instances.

The ledmon application does not recognize PFA state (Predicted Failure Analysis), hence the PFA pattern from SFF-8489 specification is not visualized. SEE ALSO

fruled(1) General Commands Manual fruled(1) NAME
fruled - flash/turn off attention LEDs (cell, cabinet and I/O chassis attention LEDs) SYNOPSIS
cell cell]... username I/Ochassis I/Ochassis]... username cabinet cabinet]... username cabinet] cabinet]... username DESCRIPTION
The command flashes/turns off attention LEDs of cells or I/O chassis in the local complex. The command can also be used to start flashing or stop flashing cabinet number LEDs. If either the option or the option is specified, the scope of the command will be the specified tar- get complex. If a cell or I/O chassis attention LED is made to flash, the cabinet number LED of the cabinet that contains the cell/ I/O chassis can also be made to flash by using the option. Likewise, if a cell or I/O chassis's LED is being turned off, the cabinet number LED can also be made to stop flashing using the option. Note: This command does not read or display the state of any LED. Users must observe the hardware itself to determine the state. Refer to the for a description of the partition management terms used in this man page. Options and Arguments recognizes the following command line options and arguments: Start or stop flashing the cabinet number LED of the cabinet that contains the cell or I/O chassis. The option is only available with the and options. Start flashing or stop flashing the cabinet number LED of the specified cabinet. Turn off all cell attention LEDs. Flash/Turn off the specified cell attention LED. A cell can be specified either in the local (cabinet#/slot#) or global (cell#) format. For example, the cell located in cabinet 0, slot 4 is locally identified as 0/4 or globally as simply 4. Turn off specified attention LED(s). This is the default. Allows access to the complex specified by the option. The accessed complex is then considered the target complex. Access is through the service processor's LAN port. The option is required if this option is used. If this option is specified, the command prompts for the password. If an error is reported when you attempt to connect using this option, check to see that IPMI LAN access has not been disabled on the remote service processor. Access to the complex through IPMI over LAN can be enabled or disabled by logging on to the service processor and using the command from the Command Menu. The and options are mutually exclusive. This option should only be used in combination with either the option. IPaddress|hostname specifies the IP address or hostname of the target partition or complex Turn off all I/O chassis LEDs. Flash/Turn off the specified I/Ochassis attention LED. An I/Ochassis must be specified in the form of cabinet#/enclosure#/chassis#. For example, the I/O chassis located in cabinet 0, enclosure 1 and I/O chassis slot 1 is identified as 0/1/1. Limit the scope of the or option to a given cabinet. Start flashing specified attention LED(s). The option is unavailable with or The and options are mutually exclusive. Specifies the required authorization to access a partition other than the local partition (but can also be used as a loopback access to the local partition). The complex to be modified is the one in which this target partition resides. The option is required if this option is used. If this option is specified, the command prompts for the password. username specifies a configured user name on the target partition. Note: This command is a Web-Based Enterprise Management (WBEM) Client Application. The option accesses the target partition using a Secure Sockets Layer (SSL) connection. If errors are reported, check that the conditions described in the section are satisfied. Mapping of Global Cell Numbers to Local Cell Numbers The cabinets in a complex are numbered starting from 0. The cell slots in each cabinet are also numbered starting from 0. Each cabinet can have a maximum of 8 cells. For example, the cells located in cabinet 0 will have the following cell numbers in global format: 0, 1, 2, 3, 4, 5, 6, 7. The cell numbers in corresponding local format will be 0/0, 0/1, 0/2, 0/3, 0/4, 0/5, 0/6, 0/7. Similarly the cells located in cabinet 1 will have the following cell numbers in global format: 8, 9, 10, 11, 12, 13, 14, 15. The cell numbers in corresponding local format will be 1/0, 1/1, 1/2, 1/3, 1/4, 1/5, 1/6, 1/7. From the above convention the cell located in cabinet 1, slot 0 is identified in the local format as 1/0 or in the global format as 8. The command will display the above cell as "cab1,cell0". The cell located in cabinet 1, slot 4 is identified in the local format as 1/4 or in the global format as 12. The command will display the above cell as "cab1,cell4". See parstatus(1). RETURN VALUE
The command exits with one of the following values: Successful completion. Error condition occurred. No LED associated with specified object. EXAMPLES
Flash the attention LED of the cell located in cabinet 0 slot 4 and also flash the attention LED of the cabinet in which it is contained. Turn off the attention LEDs of 2 cells located in cabinet 0, slot 4 and cabinet 0, slot 6. DEPENDENCIES
This command uses the Web-Based Enterprise Management (WBEM) product and some of its configuration settings. If you encounter connection errors when using the option, check that the following two conditions are satisfied: o Use the command (see cimconfig(1M) in the WBEM product documentation) to verify (and correct if necessary) the setting of the following two variables: o o o The target partition's digital certificate has been appended to the local partition's Shared Authentication Store. For the nPartition commands, the Shared Authentication Store is stored in the file: This file is used by all the clients, which use SSL based certificates. If these clients trust a target partition, then the nPartition commands will also trust the target partition. Refer to the WBEM documents specified in the section below for further information.
