[ -u username -h IPaddress|hostname
| -g -h IPaddress|hostname ]

fruled -b cabinet [-b...] [-f|-o]

[ -u username -h IPaddress|hostname

DESCRIPTION

The fruled 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 -u option or the -g option is specified, the scope of the command will be the specified target 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 -B 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 -B option.

Note: This command does not read or display the state of any LED. Users must observe the hardware itself to determine the state.

Please refer to the HP System Partitions Guide for a description of the partition management terms used in this man page.

Remote Management Options

The -u and -g options will be available only if NParProvider and NPartition products are installed. The cplxmodify command exist only if NPartition product is installed.

Options and Arguments

fruled recognizes the following command line options and arguments:

-f

Turn off specified attention LED(s). This is the default.

-o

Start flashing specified attention LED(s).

The -o option is unavailable with -C or -I. The -f and -o options are mutually exclusive.

-B

Start or stop flashing the cabinet number LED of the cabinet that contains the cell or I/O chassis. The -B option is only available with the -c and -i options.

-u username

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 -h option is required if this option is used.

username specifies a configured user name on the target partition. If -u username is specified, the command will prompt for the password associated with the username.

Note: This command is a Web-Based Enterprise Management (WBEM) Client Application. The -u option accesses the target partition using a Secure Sockets Layer (SSL) connection. If errors are reported, check that the conditions described in the DEPENDENCIES section are satisfied.

Note: If the commands are used in a script, the user password must be passed in a secured way. For example,

1.

Save the user password in a variable and pass it to the command as,

echo $passwd | parstatus -X -u username -h hostname/IP

2.

Save the user password in a file and pass the file as input to the command like,

parstatus -X -u username -h hostname/IP < passwd_file

Note, for security reason, protect the file that has the user password by removing read permissions for non-privileged users.

-h IPaddress|hostname

This option should only be used in combination with either the -u or -g option. IPaddress|hostname specifies the IP address or hostname of the target partition (-u) or complex (-g).

-g

Allows access to the complex specified by the -h option. The accessed complex is then considered the target complex. Access is via the service processor's LAN port.

The -h option is required if this option is used.

If -g is specified, the IPMI password of the service processor should be passed when prompted.

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 via IPMI over LAN can be enabled or disabled by logging on to the service processor and using the SA command from the Command Menu.

The -u and -g options are mutually exclusive.

Note: If the commands are used in a script, the IPMI password must be passed in a secured way. For example,

1.

Save the user password in a variable and pass it to the command as,

echo $passwd | parstatus -X -g -h hostname/IP

2.

Save the user password in a file and pass the file as input to the command like,

parstatus -X -g -h hostname/IP < passwd_file

Note, for security reason, protect the file that has the IPMI password by removing read permissions for non-privileged users.

-c cell

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.

-i I/Ochassis

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.

-b cabinet

Start flashing or stop flashing the cabinet number LED of the specified cabinet.

-C

Turn off all cell attention LEDs.

-I

Turn off all I/O chassis LEDs.

-l cabinet

Limit the scope of the -C or -I option to a given cabinet.

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 parstatus(1) 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 parstatus(1) command will display the above cell as "cab1,cell4".

RETURN VALUE

The fruled command exits with one of the following values:

0: Successful completion.
1: Error condition occurred.
2: 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.

fruled -o -B -c 0/4  

Turn off the attention LEDs of 2 cells located in cabinet 0, slot 4 and cabinet 0, slot 6.

fruled -f -c 0/4 -c 0/6 

DEPENDENCIES

This command uses the Web-Based Enterprise Management (WBEM) product and certain of its configuration settings. If you encounter connection errors when using the -u option, check that the following two conditions are satisfied:

Use the cimconfig(1M) command to verify (and correct if necessary) the setting of the following two variables:
- enableRemotePrivilegedUserAccess=true
- enableHttpsConnection=true
You must have appended the target partition's digital certificate to the local partition's Trust Store file. For the nPartition commands, the Trust Store file is /opt/nparcmds/nparcmds.pem.

Refer to the WBEM documents specified in the SEE ALSO section below for further information.
