Reference Guide

Property Description
• 30 = Non-recoverable error - The element has completely failed, and
recovery is not possible. All functionality provided by this element has
been lost.
• .. = DMTF Reserved
NumberOfBlocks
Total number of logically contiguous blocks, of size Block Size, which form this
Extent. The total size of the Extent can be calculated by multiplying BlockSize by
NumberOfBlocks. If the BlockSize is 1, this property is the total size of the Extent.
OperationalStatus
Indicates the current statuses of the element. Various operational statuses are
defined. Many of the enumeration's values are self-explanatory.
Possible values are:
• 0 = Unknown
• 1 = Other
• 2 = OK
• 3 = Degraded
• 4 = Stressed - Indicates that the element is functioning, but needs
attention. Examples of "Stressed" states are overload, overheated, and so
on.
• 5 = Predictive Failure - Indicates that an element is functioning nominally
but predicting a failure in the near future.
• 6 = Error
• 7 = Non-Recoverable Error
• 8 = Starting
• 9 = Stopping
• 10 = Stopped
• 11 = In Service - Describes an element being configured, maintained,
cleaned, or otherwise administered.
• 12 = No Contact - Indicates that the monitoring system has knowledge of
this element, but has never been able to establish communications with it.
• 13 = Lost Communication - Indicates that the ManagedSystem Element is
known to exist and has been contacted successfully in the past, but is
currently unreachable.
• 14 = Aborted
• 15 = Dormant - Indicates that the element is inactive or quiesced.
• 16 = Supporting Entity in Error - Indicates that this element may be "OK" but
that another element, on which it is dependent, is in error. An example is a
network service or endpoint that cannot function due to lower-layer
networking problems.
• 17 = Completed - Indicates that the element has completed its operation.
This value should be combined with either OK, Error, or Degraded so that a
client can tell if the complete operation Completed with OK (passed),
Completed with Error (failed), or Completed with Degraded (the operation
finished, but it did not complete OK or did not report an error).
• 18 = Power Mode - Indicates that the element has additional power model
information contained in the Associated PowerManagementService
association.
• .. = DMTF Reserved
• 0x8000.. = Vendor Reserved
OperationalStatus replaces the Status property on ManagedSystemElement to
provide a consistent approach to enumerations, to address implementation needs
for an array property, and to provide a migration path from today's environment to
