You can turn hardware attention indicators (LEDs) on or off by using any one of the following procedures:

HP's nPartition systems provide attention indicators (LEDs) to help you to visually select and confirm which hardware you want to perform operations on. Attention indicators are amber (orange) lights.

Table 7-2 lists the meanings for the various attention indicator states. When all components of a system are functioning and no service operations are occurring, every attention indicator should be turned off. (HP Superdome cabinet number LCDs remain lit or blinking when cabinet power is on.)

Table 7-2 Attention Indicator (LED) States and Meanings

Attention Indicator StateMeaning

OFF

Not selected.

BLINKING

Selected to be used in a service operation.

ON

Supported for PCI card slot LEDs only.

Service required, problems have been identified with the component.

 

LEDs for Hardware Components. You can control (turn off, blink, and/or turn on) attention indicators for the following hardware components.

  • Cell LEDs. Each cell or cell slot has its own attention indicators.

    • On HP Superdome servers, each cell attention indicator is located on the server cabinet hardware below the cell slot, just to the right of the power LED for the cell slot.

    • On other Partition-capable servers, each cell attention indicator is located on the cell hardware, to the outside of the power LEDs for the cell.

  • I/O Chassis LEDs. On HP Superdome servers only, each I/O chassis has a attention indicator, which is located on the cabinet above the I/O chassis.

  • PCI Card Slot LEDs. On all HP nPartition systems, each PCI card slot has an attention indicator that you can use to select the card slot. You can view the attention indicator for a PCI card slot when accessing the card cage.

    On HP rp7405/rp7410, rp7420, rx7620, rp8400, rp8420, and rx8620 servers only, you also can view the attention indicator for each PCI slot beneath the corresponding slot, on the external chassis at the rear of the server cabinet.

  • Cabinet Number LCDs. On HP Superdome servers only, each cabinet has a cabinet number LCD that serves as the attention indicator for the cabinet.

NOTE: The cabinet "attention" light on HP's nPartition capable servers is not user-controllable.

The cabinet attention light automatically turns on when one or more alert level 6 (or higher) chassis codes has been recorded in the error logs and has not yet been read. This light automatically turns off when a user enters the service processor (GSP or MP) chassis logs or event logs viewer.

Procedure 7-6 Turning Attention Indicators On and Off (nPartition Commands)

From the command line, you can turn attention indicators on or off by using the fruled command, the rad command (HP-UX B.11.11 only), and the olrad command (HP-UX B.11.23 and HP-UX B.11.31).

You can use the fruled command and specify -o or -f and a cabinet, cell, or I/O chassis: -o option to blink the LED, -f option to turn off the LED, -b# for a cabinet (where # is the cabinet number), -c# for a cell (where # is the cell number), -i #/#/# for an I/O chassis (where #/#/# is the cabinet/bay/chassis).

HP-UX B.11.11 supports the rad command for controlling PCI card slot attention indicators and other tasks.

HP-UX B.11.23 and HP-UX B.11.31 support the olrad command for controlling PCI card slot attention indicators and other tasks.

NOTE: You can remotely perform this task using remote administration options supported by the Enhanced nPartition Commands or Partition Manager Version 2.0. Remote administration is supported by the Partition Manager Tools->Switch Complexes action and by the nPartition command -u... -h... options or -g... -h... options.

For details see “Tools for Managing Hardware”.

  1. Login to a system with the nPartition commands installed.

    If using remote administration features to turn attention indicators on or off, you can login to any system with Enhanced nPartition Commands installed.

    To manage PCI slot attention indicators, you must access HP-UX in the local nPartition where the PCI slot resides (the nPartition to which the cell attached to the I/O chassis containing the PCI slot is assigned).

  2. Use the fruled command and either the rad command (HP-UX B.11.11) or the olrad command (HP-UX B.11.23 and HP-UX B.11.31) to manage (turn on, off, or blink) the attention indicator for a system hardware component.

    From the command line you can manage LEDs for the following hardware components:

    • Cells—Use fruled to blink or turn off a cell attention indicator.

      • Turn Off: The fruled -f -c# command turns off the attention indicator for the specified cell (-c#). To turn off all cell attention indicators use the fruled -f -C command.

      • Blink: The fruled -o -c# command blinks the attention indicator for the specified cell (-c#).

    • I/O Chassis—Use fruled to blink or turn off HP Superdome I/O chassis attention indicators.

      Specify the I/O chassis using cabinet/bay/chassis notation (#/#/#).

      • Turn Off: The fruled -f -i#/#/# command turns off the attention indicator for the specified I/O chassis (-i#/#/#). To turn off all I/O chassis attention indicators use the fruled -f -I command.

      • Blink: The fruled -o -i#/#/# command blinks the attention indicator for the specified I/O chassis (-i#/#/#).

    • Cabinet Numbers—Use fruled to blink or not-blink (keep lit) the cabinet number LCD for an HP Superdome cabinet.

      • Not-Blink: The fruled -f -b# command stops blinking (keeps it lit) the cabinet number LCD for the specified cabinet (-b#).

      • Blink: The fruled -o -b# command blinks the cabinet number LCD for the specified cabinet (-b#).

    • PCI Card Slots—Managing the attention indicator for a PCI card slot is supported from HP-UX only.

      Use the rad command (HP-UX B.11.11 only) or olrad command (HP-UX B.11.23 and HP-UX B.11.31) to turn on, off, or blink the attention indicator for a PCI card slot.

      Specify the PCI slot using cabinet-bay-chassis-slot (#-#-#-#) notation.

      • Turn Off PCI Card Slot Attention Indicator

        The HP-UX B.11.11 rad -f off slot command turns off the attention indicator for the specified PCI card slot (slot).

        The HP-UX B.11.23 and HP-UX B.11.31 olrad -I OFF slot command turns off the attention indicator for the specified PCI card slot (slot).

      • Blink PCI Card Slot Attention Indicator

        The HP-UX B.11.11 rad -f attention slot command blinks the attention indicator for the specified PCI card slot (slot).

        The HP-UX B.11.23 and HP-UX B.11.31 olrad -f ATTN slot command blinks the attention indicator for the specified PCI card slot (slot).

      • Turn On PCI Card Slot Attention Indicator

        The HP-UX B.11.11 rad -f on slot command turns on the attention indicator for the specified PCI card slot (slot).

        The HP-UX B.11.23 and HP-UX B.11.31 olrad command does not support turning on a PCI card slot's attention indicator to a steady-on state.

    For details refer to the fruled(1), rad(1M), or olrad(1M) manpage.

    The following HP-UX B.11.11 example turns off and blinks various attention indicators on an HP Superdome system, including cell, I/O chassis, PCI slot, and cabinet LEDs.

    Example 7-1 Turning Attention Indicators On and Off

    # fruled -f -C 1 # fruled -f -I # fruled -o -c0 -c2 -c4 2 # fruled -o -i0/0/1 -i0/0/3 # fruled -o -b0 # fruled -f -C 3 # fruled -f -I # fruled -f -b0 # rad -f attention 0-0-1-2 4 # rad -f off 0-0-1-2 #
    1

    Turn off all cell and I/O chassis attention indicators.

    2

    Blink attention indicators for cells 0, 2, and 4 and I/O chassis 0/0/1 and 0/0/3. Blink the cabinet number LCD for cabinet 0.

    3

    Turn off all cell and I/O chassis attention indicators and stop blinking the cabinet number LCD.

    4

    Blink the attention indicator for PCI slot 2 in cabinet 0, bay 0, chassis 1. Then turn off the same PCI slot attention indicator.
