This is a true/false flag on the HddMotherBoardTempStats object indicating whether UCS Manager considers this particular temperature sample unreliable. An admin should treat any accompanying temperature readings with caution when this flag is set, since a suspect sample means the collection process itself, not necessarily the hardware, may be the source of an odd value, so alarms should not be trusted at face value. For example, if the right-outlet temperature jumps implausibly high in one polling cycle but this Suspect flag is true for that same sample, the admin would wait for the next clean sample rather than immediately escalating a thermal event.
