##### 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.

Table 25 Oracle ILOM Properties Used to Manage POST Operations

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 is a graphic illustration of the same set of Oracle ILOM `set` command variables.
