We use HMC to manage two logical partitions. LPARs don't have any problem but HMC's, itself, attention led is on. :eek: I am not sure if that's going to affect LPARs, but just wanted to be sure.... :confused:

LED(4) BSD Kernel Interfaces Manual LED(4)
NAME
led -- API for manipulating LED's, lamps and other annunciators
SYNOPSIS
#include <dev/led/led.h>
typedef void led_t(void *priv, int onoff);
struct cdev *
led_create_state(led_t *func, void *priv, char const *name, int state);
struct cdev *
led_create(led_t *func, void *priv, char const *name);
void
led_destroy(struct cdev *);
DESCRIPTION
The led driver provides generic support for handling LEDs, lamps and other annunciators.
The hardware driver must supply a function to turn the annunciator on and off and the device name of the annunciator relative to /dev/led/.
The priv argument is passed back to this on/off function and can be used however the hardware driver sees fit.
The lamp can be controlled by opening and writing ASCII strings to the /dev/led/bla device.
In the following, we will use this special notation to indicate the resulting output of the annunciator:
* The annunciator is on for 1/10th second.
_ The annunciator is off for 1/10th second.
State can be set directly, and since the change happens immediately, it is possible to flash the annunciator with very short periods and syn-
chronize it with program events. It should be noted that there is a non-trivial overhead, so this may not be usable for benchmarking or mea-
suring short intervals.
0 Turn the annunciator off immediately.
1 Turn the annunciator on immediately.
Flashing can be set with a given period. The pattern continues endlessly.
f _*
f1 _*
f2 __**
f3 ___***
...
f9 _________*********
Three high-level commands are available:
d%d Numbers. Each digit is blinked out at 1/10th second, zero as ten pulses. Between digits a one second pause and after the last
digit a two second pause after which the sequence is repeated.
s%s String. This gives full control over the annunciator. Letters 'A' ... 'J' turn the annunciator on for from 1/10th to one full
second. Letters 'a' ... 'j' turn the annunciator off for 1/10th to one full second. Letters 'u' and 'U' turn the annunciator
off and on respectively when the next UTC second starts. Unless terminated with a '.', the sequence is immediately repeated.
m%s Morse.
'.' becomes '_*'
'-' becomes '_***'
' ' becomes '__'
'
' becomes '____'
The sequence is repeated after a one second pause.
