Netra-T1 AC200 LOM Usage -

There are three prompts available on the Netra-t1.
  ok> 	-------------------- (normal prompt when the OS is not running)
  lom>  -------------------- (available whether OS is running or not)
  # 	-------------------- (the OS prompt)

To move between the "ok>" prompt and the "lom>" prompt, type:
  ok> #. 	There must be less than 1 second between the "#" and "." 
  lom> 	------>	This is the prompt you get 

Root can change this character sequence:
  # lomctl <new first character>

  Only the first character ("#") can be changed. You don't need to know the previous 
  character to do this.

To find out the current sequence do an "init 5":
  # init 5
  This shuts down the system and gives you the "lom>" prompt

Then to show the current two-character sequence type:
  lom> show escape

To move between the "lom>" prompt and the "ok>" prompt type:
  lom> console

See Infodoc 27372 for a flow chart of how to jump around between the "lom>", 
"ok>" and "OS" prompts.

Some useful lom> commands are:

lom> poweron 	-------	(powers on the netra)
lom> poweroff 	-------	(powers off the netra)
lom> reset 	-------	(the same as the ok> reset command)
lom> reset -x 	-------	(resets the CPU only- externally initiated reset XIR)
lom> break 	-------	(goes to the ok> prompt from the OS- "Stop-a")
lom> environment-------	(current status of all components in system)
lom> check 	------- (updates component status after repairing it-
			 run "lom> environment" again)
lom> show eventlog ---- (show last 10 events on the system)
lom> set faulton ------ (turns on the fault LED)
lom> set faultoff ----- (turns off the fault LED)
lom> set alarmon [1-3] -(sets 1 of 3 alarms on)
lom> set alarmoff [1-3] -(sets 1 of 3 alarms off)
lom> show model -------	(show the server model)
lom> show hostname ----	(same as uname -n)
lom> show -------------	(help for the "show" command)
lom> help -------------	(list of LOM commands)      

You can set the boot mode of a netra using the below "lom>" command:

  lom> bootmode [-u][normal|forth|reset_nvram|diag|skip_diag]

	-u  	allows sharing of the console and LOM device 

	normal	server boots using the OBP environment settings  
		-must reset server to take effect

	forth 	server stops at the "ok>" prompt- same as "Stop-f"  
		-must reset server to take effect

	reset_nvram -"ok> set-defaults" or "Stop-n"  
		-must reset server to take effect

	diag 	runs full POST- "ok> diag-switch? true" or "Stop-d"  
		-must power off server and back on within 10 minutes

	skip_diag - ok> setenv diag-switch? false"  
		-must power off server and back on within 10 minutes
