lom — lights out
management
lom* at ebus?
The lom driver provides support for the
LOMlite lights out management module found on Sun Netra t1 systems and the
LOMlite2 module found on Sun Fire V100/V120 and Sun Netra X1 systems.
Temperature readings, PSU status and fan status provided by the LOM are made
available through the
sysctl(8) interface. The
integrated watchdog(4)
timer can be configured through the
sysctl(8) interface as well.
The watchdog timer supports timeouts between 1 and 126 seconds. If the
watchdog is disabled, which is its default state, it will turn on the
system's fault LED after the maximum timeout of 126 seconds.
The lom driver will update the hostname
stored in the LOM whenever the system's hostname is changed.
