Oracle ILOM Properties That Affect POST Behavior

The following table describes the Oracle ILOM properties that determine how POST performs its operations.

Note - The value of keyswitch_state must be normal when individual POST parameters are changed.

Parameter	Values	Description
`/SYS keyswitch_state`	`normal`	The system can power on and run POST (based on the other parameter settings). This parameter overrides all other commands.
	`diag`	The system runs POST based on predetermined settings.
	`standby`	The system cannot power on.
	`locked`	The system can power on and run POST, but no flash updates can be made.
`/HOST/diag mode`	`off`	POST does not run.
	`normal`	Runs POST according to `diag level` value.
	`service`	Runs POST with preset values for `diag level` and `diag verbosity`.
`/HOST/diag level`	`max`	If `diag mode` = `normal`, runs all the minimum tests plus extensive processor and memory tests.
	`min`	If `diag mode` = `normal`, runs minimum set of tests.
`/HOST/diag trigger`	`none`	Does not run POST on reset.
	`hw-change`	(Default) Runs POST following an AC power cycle and when the top cover is removed.
	`power-on-reset`	Only runs POST for the first power on.
	`error-reset`	(Default) Runs POST if fatal errors are detected.
	`all-resets`	Runs POST after any reset.
`/HOST/diag verbosity`	`normal`	POST output displays all test and informational messages.
	`min`	POST output displays functional tests with a banner and pinwheel.
	`max`	POST displays all test, informational, and some debugging messages.
	debug
	`none`	No POST output is displayed.

The following flowchart illustrates the same set of Oracle ILOM set command variables.

image:Flowchart diagram shows the Oracle ILOM properties used to manage POST operations.

The following table shows combinations of Oracle ILOM parameters and associated POST modes.

Oracle ILOM Parameter	Normal Diagnostic Mode (Default Settings)	No POST Execution	Service Mode Using the Keyswitch_state
`keyswitch_state`¹	`normal`	`normal`	`diag`
`/HOST/diag mode`	`normal`	`Off`	N/A
`/HOST/diag level`	`max`	N/A	N/A
`/HOST/diag trigger`	`hw-change` `error-reset`	`none`	N/A
`/HOST/diag verbosity`	`normal`	N/A	N/A
Description of POST Execution	This is the default POST configuration. This configuration tests the system thoroughly and suppresses some of the detailed POST output.	POST does not run, resulting in quick system initialization. This configuration is not suggested.	POST runs the full spectrum of tests with the maximum output displayed.

¹The keyswitch_state parameter, when set to diag, overrides all the other POST variables.
