Chapter 9 Monitoring and Managing the System 85
Similarly, by default, the LOM attempts to disable its watchdog timer if it detects
that the system has undergone a ‘panic’. If you do not want the LOM to attempt to
disable its
tsdog
watchdog timer after a panic, edit the
disable_wdog_on_panic
line to read:
Other Ways of Configuring the LOM
The LOM device takes its configuration from a file called
lom.conf
. This is stored
in
/kernel/drv
.
The full list of parameters you can set in this file is given in
TABLE 9-2
.
disable_wdog_on_panic=0
TABLE 9-2
LOM Configuration File Parameters
Field Format Effect
wdog_enabled
Boolean Enables the
tsdog
watchdog when the
LOM driver loads.
wdog_reset
Boolean Causes the LOM to reset the Netra t1
after a
tsdog
watchdog timeout.
wdog_alarm3
Boolean Turns on software alarm 3 when the
tsdog
watchdog times out.
wdog_timeout
Integer Sets the timeout for the
tsdog
watchdog. The value is in seconds. If
the system locks up and the LOM
device does not receive the expected
‘pat’ from the
tsdog
watchdog, then,
after the timeout period that you
specify, the LOM device reports an
event, lights the Fault LED, and if
configured to do so (see
wdog_reset
above) resets the Netra t1 system.
serial_events
Boolean Causes the LOM to report events over
the serial connection.
disable_wdog_on_break
Boolean Causes the LOM to disable its
tsdog
watchdog if a break signal is detected
on the Serial A/LOM port.
disable_wdog_on_panic
Boolean Causes the LOM to try to disable the
LOM watchdog after a system ‘panic’.
