LOM(4)               OpenBSD Programmer's Manual (SPARC64)              LOM(4)

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 X1 systems.  Temperature readings, PSU sta-
     tus 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.
