Using The Netra T1 Lomlite Device - Sun Microsystems Netra t1 LOMlite Arbeiten

Using the Netra t1 LOMlite Device

The LOMlite device provides lights out management or remote management of a
Netra t1 system over a serial connection. While the system is running, LOMlite also
provides event reporting via the Solaris operating environment.
The LOMlite Device
LOMlite monitors the status of the PSU and fans in the system. It provides a fault
LED to notify the operator of events or failures. It also provides a host watchdog
which can reset the system in the event of a lockup.
The current status of the system can be displayed by using either the serial
command interface or the UNIX driver.
LOMlite also provides the capability to power the system up, to return it to standby
mode, and to reset the host from the serial command interface.
Events such as fan failures and alarm state changes are stored in an event log of ten
events. The oldest fatal event is stored separately as the most likely cause of
subsequent failures.To avoid filling the event log with repeated failures from a given
source, only the first failure from any given source is stored. Once the operator has
cleared the fault, monitoring of the failed device is re-enabled. This is performed
either by restoring standby power to the system (if the system was powered off to
repair the fault), or by issuing a check command at the LOMlite prompt. Re-
enabling monitoring of a device also clears the error indication on the fault LED.
All device state changes are reported via the interface to the Solaris driver. which
has more resources available for storage of such events.
