MS_HW_DISKCONTROLLER

A disk controller is a card inside a computer that connects one or several physical disk drives to this computer. Some intelligent disk controllers (such as RAID controllers) manage several physical disks as a single logical disk which is the only disk exposed to the operating system. Monitoring both physical and logical disks is essential to ensure that the storage is available.

The purpose of the Disk controller instance is to act as a container for Logical Disks and Physical Disks monitoring, and symbolize the way hard drives are setup on the platform.

Please note, however, that if a controller goes missing, all its disk dependencies will be missing as well. In addition, some information regarding the Disk Controllers, like their brand, model or driver version, is displayed in their infobox.

Parameters

Parameter	Description	Unit	Default Alert Thresholds	Type
BatteryStatus	This parameter triggers an alert to predict that the disk controller battery will be unable to support the controller in the event of a power failure. Value set by diskcontrollerColl every 2 minutes.	{0 = OK; 1 = Degraded; 2 = Failed}	1 = Warning 2 = Alarm	Availability
ControllerStatus	This parameter displays the status of the disk controller. Value set by diskcontrollerColl every 2 minutes.	{0 = OK; 1 = Degraded; 2 = Failed}	1 = Warning 2 = Alarm	Availability
Missing (**)	When the disk controller is no longer discovered, the parameter goes into alarm	{0 = Present ; 1 = Missing}	1 = Alarm	Availability
StatusInformation	Additional (textual) information about the current status of the Disk Controller.	n/a	None	--

(*)

These thresholds are automatically set by Hardware Sentry KM according to your environment and the recommendation of the system manufacturer during each discovery (by default, every hour). To customize these thresholds and prevent Hardware Sentry KM from overwriting your settings, you will need to use the “Modify Thresholds” KM Command.
It is not recommended to modify these thresholds.

(**)

The “Missing” parameter is dynamically activated only when the monitored component goes missing. As long as the monitored component is properly discovered and monitored, the “Missing” parameter cannot be displayed in the console. When the “Missing” parameter is activated, its value is always ‘1’, which triggers an alarm. You can disable the missing device detection mechanism in the settings of the KM.

Depending on your system, all parameters may not be used. Only one of the parameters may be visible. This will not affect the proper monitoring of the device.
