74 Sun Fire V100 Server User’s Guide • December 2001
You can turn the option on and off from the Solaris command prompt. For more
information, see “To Set the Hardware Reset Option From a Script or Command
(lom -R on)” on page 75.
However, as long as you have the -R on option set in /etc/rc2.d/S25lom, the
Hardware Reset option will always be enabled when you start the system.
Enabling the LOM Watchdog Process From Your
Own Script or Command (lom -W on)
Note – You do not normally need to do this. If you want to configure LOM to
perform an automatic server restart after a lockup, see “To Configure the LOM ASR”
on page 73. Use the lom -W on option on the command line or in another script file
only if you have removed the
/etc/rc2.d/S25lom script.
By default, the LOM watchdog process is enabled, and if you type
lom -W on while the watchdog process is already running, the command will have
no effect. You can run this command only if you have removed the
/etc/rc2.d/S25lom script file, or if you have turned the watchdog off manually
by using the lom -W off command.
The default priocntl command is:
priocntl -e -c RT lom -W on,40000,10000
The number 40,000 on this command line indicates the watchdog’s timeout period in
milliseconds; you can specify a different number. The number 10,000 indicates its pat
interval in milliseconds; again, you can specify a different number.
Note – Do not specify a watchdog timeout period of less than 5000 milliseconds. If
you do, the watchdog times out frequently even though the server has not locked
up.
If the watchdog process times out (in other words, if it does not receive its expected
pat), the LOM device will turn on the server’s front and back Fault LEDs and
generate a LOM event report. However, it will not automatically reset the system. To
make it reset the system, you must use the -R option. For more information, see “To
Set the Hardware Reset Option From a Script or Command (lom -R on)” on page 75.
