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) inter-
     face.  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.
