# NAME

lom — lights out management

# SYNOPSIS

lom* at ebus?

# DESCRIPTION

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 T1/X1 systems. Fault LED and alarms status, temperature readings, PSU status and fan status provided by the LOM are made available through the envstat(8) interface. The integrated watchdog timer can be configured through the wdogctl(8) interface. The watchdog timer supports timeouts between 1 and 126 seconds.

Fault LED and alarms status can be changed through the sysctl(8) interface. An entry for the lom driver is created under the hw.lomN MIB.

The lom driver will update the hostname stored in the LOM whenever the system's hostname is changed.
