Dell Command | Monitor Version 9.1 Reference Guide

Access describes whether the media is readable (value = 1), writeable (value = 2), or both (value = 3). Unknown (0) and Write Once (4) can also be defined.

Possible values are:

• 0 = Unknown
• 1 = Readable
• 2 = Writeable
• 3 = Read/Write Supported
• 4 = Write Once

Size in bytes of the blocks which form this StorageExtent. If variable block size, then the maximum block size in bytes should be specified. If the block size is unknown or if a block concept is not valid (for example, for AggregateExtents, Memory or LogicalDisks), enter a 1.

The maximum number of blocks, of size BlockSize, which are available for consumption when layering StorageExtents using the BasedOn association. This property only has meaning when this StorageExtent is an Antecedent reference in a BasedOn relationship. For example, a StorageExtent could be composed of 120 blocks. However, the Extent itself may use 20 blocks for redundancy data. If another StorageExtent is BasedOn this Extent, only 100 blocks would be available to it. This information (100 blocks is available for consumption) is indicated in the ConsumableBlocks property.

Indicates the name of the class or the subclass used in the creation of an instance. When used with the other key properties of this class, this property allows all instances of this class and its subclasses to be uniquely identified.

An address or other identifying information used to uniquely name the LogicalDevice.

A user-friendly name for the object. This property allows each instance to define a user-friendly name in addition to its key properties, identity data, and description information.

An enumerated value indicating an administrator's default or startup configuration for the Enabled State of an element.

Possible values are:

• 2 = Enabled
• 3 = Disabled
• 5 = Not Applicable
• 6 = Enabled but Offline
• 7 = No Default
• 9 = Quiesce
• .. = DMTF Reserved
• 32768..65535 = Vendor Reserved

An integer enumeration that indicates the enabled and disabled states of an element. It can also indicate the transitions between these requested states. For example, shutting down (value = 4) and starting (value = 10) are transient states between enabled and disabled.

Possible values are:

• 0 = Unknown
• 1 = Other
• 2 = Enabled — Indicates that the element is or could be executing commands, will process any queued commands, and queues new requests.
• 3 = Disabled — Indicates that the element will not execute commands and will drop any new requests.
• 4 = Shutting Down — Indicates that the element is in the process of going to a Disabled state.
• 5 = Not Applicable — Indicates the element does not support being enabled or disabled.
• 6 = Enabled but Offline — Indicates that the element may be completing commands, and will drop any new requests.
• 7 = In Test — Indicates that the element is in a test state.
• 8 = Deferred — Indicates that the element may be completing commands, but will queue any new requests.
• 9 = Quiesce — Indicates that the element is enabled but in a restricted mode.
• 10 = Starting — Indicates that the element is in the process of going to an Enabled state. New requests are queued.
• 11..32767 = DMTF Reserved
• 32768..65535 = Vendor Reserved

ErrorMethodology for Memory is a string property that indicates whether parity or CRC algorithms, ECC or other mechanisms are used. Details on the algorithm can also be supplied.

An integer enumeration indicating that active memory has failed and the spare or backup memory may have taken over.

Possible values are:

• 0 = Unknown
• 1 = Other
• 2 = None
• 3 = Active

Indicates the current health of the element. This attribute expresses the health of this element but not necessarily that of its subcomponents.

Possible values are:

• 0 = Unknown — The implementation cannot report on HealthState at this time. DMTF has reserved the unused portion of the continuum for additional HealthStates in the future.
• 5 = OK — The element is fully functional and is operating within normal operational parameters and without error.
• 10 = Degraded/Warning — The element is in working order and all functionality is provided. However, the element is not working to the best of its abilities. For example, the element may not be operating at optimal performance or it may be reporting recoverable errors.
• 15 = Minor failure — All functionality is available but some may be degraded.
• 20 = Major failure — The element is failing. It is possible that some or all of the functionality of this component is degraded or not working.
• 25 = Critical failure — The element is non-functional and recovery may not be possible.
• 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

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.

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 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.

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.

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

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

An integer enumeration that indicates the last requested or desired state for the element, irrespective of the mechanism through which it was requested. The actual state of the element is represented by EnabledState. This property is provided to compare the last requested and current enabled or disabled states.

There are two new values in RequestedState that build on the statuses of EnabledState. These are Reboot (10) and Reset (11). Shut Down requests an orderly transition to the Disabled state, and may involve removing power, to completely erase any existing state. The Disabled state requests an immediate disabling of the element, such that it will not execute or accept any commands or processing requests. This property is set as the result of a method invocation (such as Start or StopService on CIM_Service), or can be overridden and defined as WRITEable in a subclass. The method approach is considered superior to a WRITEable property, because it allows an explicit invocation of the operation and the return of a result code. If knowledge of the last RequestedState is not supported for the EnabledLogicalElement, the property is NULL or has the value 12 (Not Applicable).

Possible values are:

• 0 = Unknown — Indicates the last requested state for the element is unknown.
• 2 = Enabled
• 3 = Disabled
• 4 = Shut Down
• 5 = No Change
• 6 = Offline — Indicates that the element has been requested to transition to the Enabled but Offline EnabledState.
• 7 = Test
• 8 = Deferred
• 9 = Quiesce
• 10 = Reboot — Refers to doing a Shut Down and then moving to an Enabled state.
• 11 = Reset - Indicates that the element is first Disabled and then Enabled.
• 12 = Not Applicable
• .. = DMTF Reserved
• 32768..65535 = Vendor Reserved

The CreationClassName of the scoping system.

The System Name of the scoping system.

Indicates the target state to which the instance is transitioning.

Possible values are:

• 0 = Unknown
• 2 = Enabled
• 3 = Disabled
• 4 = Shut Down
• 5 = No Change — Indicates that no transition is in progress.
• 6 = Offline
• 7 = Test
• 8 = Defer
• 9 = Quiesce
• 10 = Reboot
• 11 = Reset
• 12 = Not Applicable — Indicates the implementation does not support representing ongoing transitions.

A value other than 5 or 12 identifies the state to which the element is in the process of transitioning.

Volatile is a property that indicates whether this memory is volatile or not.
