Controlling How POST Runs

The server can be configured for normal, extensive, or no POST execution. You can

also control the level of tests that run, the amount of POST output that is displayed,

and which reset events trigger POST by using ILOM command variables.

The keyswitch_state parameter, when set to diag, overrides all the other ILOM

POST variables.

TABLE: ILOM Parameters Used for POST Configuration on page 26 lists the ILOM

variables used to configure POST. FIGURE: Flowchart of Variables for POST

Configuration on page 20 shows how the variables work together.
