Property Description
the future. This change was not made earlier because it required the deprecated
qualifier. Due to the widespread use of the existing Status property in
management applications, it is strongly recommended that providers or
instrumentation provide both the Status and OperationalStatus properties. Further,
the first value of OperationalStatus should contain the primary status for the
element. When instrumented, Status (because it is single-valued) should also
provide the primary status of the element.
OtherIdentifyingInfo
Captures data, in addition to DeviceID information, that could be used to identify a
LogicalDevice. For example, you could use this property to hold the operating
system's user-friendly name for the Device.
PrimaryStatus
Provides a high level status value, intended to align with Red-Yellow-Green type
representation of status. It should be used in conjunction with DetailedStatus to
provide high level and detailed health status of the ManagedElement and its
subcomponents.
Possible values are:
• 0 = Unknown - Indicates the implementation is in general capable of
returning this property, but is unable to do so at this time.
• 1 = OK - Indicates the ManagedElement is functioning normally.
• 2 = Degraded - Indicates the ManagedElement is functioning below
normal.
• 3 = Error - Indicates the ManagedElement is in an Error condition.
• .. = DMTF Reserved
• 0x8000.. = Vendor Reserved
Primordial
If true, "Primordial" indicates that the containing System does not have the ability
to create or delete this operational element. This is important because
StorageExtents are assembled into higher-level abstractions using the BasedOn
association. Although the higher-level abstractions can be created and deleted,
the most basic, (that is, primordial), hardware-based storage entities cannot. They
are physically realized as part of the System, or are actually managed by some
other System and imported as if they were physically realized. In other words, a
Primordial StorageExtent exists in, but is not created by its System and conversely
a non-Primordial StorageExtent is created in the context of its System. For
StorageVolumes, this property will generally be false. One use of this property is to
enable algorithms that aggregate StorageExtent. ConsumableSpace across all,
StorageExtents but that also want to distinquish the space that underlies
Primordial StoragePools. Since implementations are not required to surface all
Component StorageExtents of a StoragePool, this information is not accessible in
any other way. Purpose A free form string describing the media and/or its use.
RedundancyConfiguration is an integer enumeration indicating the redundancy
configuration when active memory fails.
Possible values are:
• 0 = Unknown
• 1 = Other
• 2 = Disabled
• 3 = Spared
• 4 = Mirrored
• 5 = LockStep
RequestedState
An integer enumeration that indicates the last requested or desired state for the
element, irrespective of the mechanism through which it was requested. The
