Discrete sensors offer a set of well-defined values associated with the sensor target. Discrete sensors typically provide information about an entity presence, entity fault, or a power supply state.
To obtain a discrete sensor reading using the ILOM CLI, you must use the cd command to navigate to the sensor target then use the show command to display the target properties. For example, on some Sun server platforms, you can determine whether a hard disk drive is present in slot 0 by specifying the following path:
cd /SYS/HDD0_PRSNT
show
The properties describing the discrete sensor target appear. For example:
Type = Entity Presence
Class = Discrete Indicator
Value = Present
