Status

Data type: string
Access type: Read-only
Qualifiers: MaxLen (10)

A string indicating the current status of the object. Various operational and non-operational statuses are defined. Operational statuses are "OK", "Degraded", "Stressed" and "Pred Fail". "Stressed" indicates that the Element is functioning, but needs attention. Examples of "Stressed" states are overload, overheated, etc. The condition "Pred Fail" (failure predicted) indicates that an Element is functioning properly but predicting a failure in the near future. An example is a SMART-enabled hard drive. Non-operational statuses can also be specified. These are "Error", "NonRecover", "Starting", "Stopping" and "Service". "NonRecover" indicates that a non-recoverable error has occurred. "Service" describes an Element being configured, maintained or cleaned, or otherwise administered. This status could apply during mirror-resilvering of a disk, reload of a user permissions list, or other administrative task. Not all such work is on-line, yet the Element is neither "OK" nor in one of the other states.

This property is inherited from CIM_ManagedSystemElement.
