CIM_AlarmDevice class

  • Article

The CIM_AlarmDevice class is an alarm device that emits audible or visible indications related to a problem situation.

The following syntax is simplified from Managed Object Format (MOF) code and includes all inherited properties. Properties are listed in alphabetic order, not MOF order.

Important

The DMTF (Distributed Management Task Force) CIM (Common Information Model) classes are the parent classes upon which WMI classes are built. WMI currently supports only the CIM 2.x version schemas.

The power management features are currently enabled but the exact feature set is unknown or the information is unavailable.

Power Saving Modes Entered Automatically (4)

The device can change its power state based on usage or other criteria.

Power State Settable (5)

The SetPowerState method is supported. This method is found on the parent CIM_LogicalDevice class and can be implemented. For more information, see Designing Managed Object Format (MOF) Classes.

PowerManagementSupported

Data type: boolean

Access type: Read-only

If TRUE, the device can be power managed, that is, put into a power-save state. If FALSE, the integer value 1 ("Not Supported") should be the only entry in the PowerManagementCapabilities array.

This property does not indicate whether power management features are currently enabled, or if enabled, which features are supported. For more information, see the PowerManagementCapabilities array.

This property is inherited from CIM_LogicalDevice.

Status

Data type: string

Access type: Read-only

Qualifiers: MaxLen (10), DisplayName ("Status")

String that indicates the current status of the object. Operational and non-operational status can be defined. Operational status can include "OK", "Degraded", and "Pred Fail". "Pred Fail" indicates that an element is functioning properly, but is predicting a failure (for example, a SMART-enabled hard disk drive).

Non-operational status can include "Error", "Starting", "Stopping", and "Service". "Service" can apply during disk mirror-resilvering, reloading a user permissions list, or other administrative work. Not all such work is online, but the managed element is neither "OK" nor in one of the other states.

Values include the following:

OK ("OK")

Error ("Error")

Degraded ("Degraded")
