Severity: 3-Major


When the fan tray is removed, the fan status in tmctl tables and 'tmsh show sys hardware' are not updated correctly to reflect the current status of the fan tray i.e. not-present.


It is important to be aware of the fan status since malfunctioning of the fan tray can result in thermal shutdown when temperature thresholds are reached. Having incorrect/incomplete status would result in delayed corrective actions if a problem should arise.


When the fan tray is physically removed.


No workaround at this time.
