Emergency Procedures Use the Break command from a terminal to perform the abort function.
LW3User.book Page 60 Wednesday, November 10, 1999 9:00 AM New Devices in the OBP Device Tree The following device has been added to the OBP device tree: ■ 60 /pci@1f,4000/ebus@1/SUNW,lom@14,200000 This is the LOMlite device. It has an FCode PROM, which allows it to identify itself to the system during probing. The FCode PROM defines the name of the device and the reg property, which describes the address space used.
LW3User.book Page 61 Wednesday, November 10, 1999 9:00 AM CHAPTER 10 Using LOMlite LOMlite is supplied on a card as part of the system and provides lights out management or remote management of the system over a serial connection. While the system is running, LOMlite also provides event reporting via the Solaris operating environment.
LW3User.book Page 62 Wednesday, November 10, 1999 9:00 AM Diagnosing PSU Faults If a PSU suffers an internal failure (that is, its output fails while input power is still applied), the Fault LED will flash and the event will be recorded as described above. For example, the message LOM event: PSU 2 Output failed may be displayed on the LOMlite console and Sep 7 11:44:20 hostname lomlited: LOMlite PSU 1 Output failed may be displayed on the Solaris console.
LW3User.book Page 63 Wednesday, November 10, 1999 9:00 AM Once a fan has been reported to have failed, any subsequent recovery and repeated failure will not be reported; that is, only one event is generated for the failure of each fan. This is to prevent the event log being rapidly filled should the fan speed fall very close to the failure threshold. Once the fault has been corrected, you can clear the event log using the Solaris lomctl clearevents command.
LW3User.book Page 64 Wednesday, November 10, 1999 9:00 AM Controlling LOMlite The following commands can be sent to LOMlite when it is connected: TABLE 10-1 LOMlite Commands Command Use alarmoff n Set alarm n off. n can be 1, 2 or 3 alarmon n Set alarm n on.
LW3User.book Page 65 Wednesday, November 10, 1999 9:00 AM Configuring LOMlite LOMlite has as an associated configuration file, lom.conf, in which you can set the following parameters: TABLE 10-2 LOMlite Configuration File Parameters Field Format Use wdog_enabled Boolean Enable the LOMlite system watchdog when driver loads. wdog_reset Boolean Reset the system after a watchdog timeout. wdog_alarm3 Boolean Turn fault LED on after a watchdog timeout.
LW3User.book Page 66 Wednesday, November 10, 1999 9:00 AM System Watchdog LOMlite includes a watchdog timer, which by default controls the system alarm. The watchdog process, tsdog, is enabled at boot time by an rc script, /etc/init.d/tsaldog. You can edit this script to configure the watchdog timeout, the reset intervals, and wether ASR is enabled. See the tsdog(1M) man page for details. Alternatively, you can disable the script, edit the driver configuration file lom.
LW3User.book Page 67 Wednesday, November 10, 1999 9:00 AM CHAPTER 11 System Shut-down The shutdown or init command is executed by the super user to change the operational state of the machine. By default, it brings the system to a state where only the console has access to the operating system. The shutdown command sends a warning message and a final message before it begins shutdown activities. Refer to shutdown(1M) and init(1M) for further information.
LW3User.book Page 68 Wednesday, November 10, 1999 9:00 AM If you have an emergency requiring an immediate system power down, switch off the system with the ON/STBY switch by holding it in the STBY position for five seconds. This does not shut down the operating system cleanly, and is likely to corrupt your file system.
