class CIM_CacheMemory : CIM_Memory

Description:

Capabilities and management of Cache Memory. Cache memory is dedicated or allocated RAM that a Processor searches first for data, before going to 'regular' memory. CacheMemory is used to speed up the delivery of data to a Processor. It is usually described by its closeness to the Processor (for example, Primary or Secondary Cache). If a DiskDrive includes RAM allocated for holding the disk's most recently read and/or adjacent data (in order to speed up retrieval), this also would be modeled as CacheMemory. Note that CacheMemory is NOT operating system or application level buffers but actual RAM allocated for caching data for a Processor, from a hard disk, etc.

Feature Type Class Origin Qualifiers
InstanceID string CIM_ManagedElement
Description InstanceID is an optional property that may be used to opaquely and uniquely identify an instance of this class within the scope of the instantiating Namespace. Various subclasses of this class may override this property to make it required, or a key. Such subclasses may also modify the preferred algorithms for ensuring uniqueness that are defined below. To ensure uniqueness within the NameSpace, the value of InstanceID should be constructed using the following "preferred" algorithm: <OrgID>:<LocalID> Where <OrgID> and <LocalID> are separated by a colon (:), and where <OrgID> must include a copyrighted, trademarked, or otherwise unique name that is owned by the business entity that is creating or defining the InstanceID or that is a registered ID assigned to the business entity by a recognized global authority. (This requirement is similar to the <Schema Name>_<Class Name> structure of Schema class names.) In addition, to ensure uniqueness, <OrgID> must not contain a colon (:). When using this algorithm, the first colon to appear in InstanceID must appear between <OrgID> and <LocalID>. <LocalID> is chosen by the business entity and should not be reused to identify different underlying (real-world) elements. If not null and the above "preferred" algorithm is not used, the defining entity must assure that the resulting InstanceID is not reused across any InstanceIDs produced by this or other providers for the NameSpace of this instance. If not set to null for DMTF-defined instances, the "preferred" algorithm must be used with the <OrgID> set to CIM.
Caption string CIM_ManagedElement
Description The Caption property is a short textual description (one- line string) of the object.
MaxLen 64
Description string CIM_ManagedElement
Description The Description property provides a textual description of the object.
ElementName string CIM_ManagedElement
Description 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. Note that the Name property of ManagedSystemElement is also defined as a user-friendly name. But, it is often subclassed to be a Key. It is not reasonable that the same property can convey both identity and a user-friendly name, without inconsistencies. Where Name exists and is not a Key (such as for instances of LogicalDevice), the same information can be present in both the Name and ElementName properties.
InstallDate datetime CIM_ManagedSystemElement
Description A datetime value that indicates when the object was installed. Lack of a value does not indicate that the object is not installed.

OperationalStatus uint16[] CIM_ManagedSystemElement
Description Indicates the current statuses of the element. Various operational statuses are defined. Many of the enumeration's values are self-explanatory. However, a few are not and are described here in more detail. "Stressed" indicates that the element is functioning, but needs attention. Examples of "Stressed" states are overload, overheated, and so on. "Predictive Failure" indicates that an element is functioning nominally but predicting a failure in the near future. "In Service" describes an element being configured, maintained, cleaned, or otherwise administered. "No Contact" indicates that the monitoring system has knowledge of this element, but has never been able to establish communications with it. "Lost Communication" indicates that the ManagedSystem Element is known to exist and has been contacted successfully in the past, but is currently unreachable. "Stopped" and "Aborted" are similar, although the former implies a clean and orderly stop, while the latter implies an abrupt stop where the state and configuration of the element might need to be updated. "Dormant" indicates that the element is inactive or quiesced. "Supporting Entity in Error" indicates that this element might 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. "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). "Power Mode" indicates that the element has additional power model information contained in the Associated PowerManagementService association. 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.

Status string CIM_ManagedSystemElement
Deprecated CIM_ManagedSystemElement.OperationalStatus
Description A string indicating the current status of the object. Various operational and non-operational statuses are defined. This property is deprecated in lieu of OperationalStatus, which includes the same semantics in its enumeration. This change is made for 3 reasons: 1) Status is more correctly defined as an array. This definition overcomes the limitation of describing status using a single value, when it is really a multi-valued property (for example, an element might be OK AND Stopped. 2) A MaxLen of 10 is too restrictive and leads to unclear enumerated values. 3) The change to a uint16 data type was discussed when CIM V2.0 was defined. However, existing V1.0 implementations used the string property and did not want to modify their code. Therefore, Status was grandfathered into the Schema. Use of the deprecated qualifier allows the maintenance of the existing property, but also permits an improved definition using OperationalStatus.

HealthState uint16 CIM_ManagedSystemElement
Description Indicates the current health of the element. This attribute expresses the health of this element but not necessarily that of its subcomponents. The possible values are 0 to 30, where 5 means the element is entirely healthy and 30 means the element is completely non-functional. The following continuum is defined: "Non-recoverable Error" (30) - The element has completely failed, and recovery is not possible. All functionality provided by this element has been lost. "Critical Failure" (25) - The element is non-functional and recovery might not be possible. "Major Failure" (20) - The element is failing. It is possible that some or all of the functionality of this component is degraded or not working. "Minor Failure" (15) - All functionality is available but some might be degraded. "Degraded/Warning" (10) - 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 might not be operating at optimal performance or it might be reporting recoverable errors. "OK" (5) - The element is fully functional and is operating within normal operational parameters and without error. "Unknown" (0) - The implementation cannot report on HealthState at this time. DMTF has reserved the unused portion of the continuum for additional HealthStates in the future.

EnabledState uint16 CIM_EnabledLogicalElement
Description EnabledState is 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. The following text briefly summarizes the various enabled and disabled states: Enabled (2) indicates that the element is or could be executing commands, will process any queued commands, and queues new requests. Disabled (3) indicates that the element will not execute commands and will drop any new requests. Shutting Down (4) indicates that the element is in the process of going to a Disabled state. Not Applicable (5) indicates the element does not support being enabled or disabled. Enabled but Offline (6) indicates that the element might be completing commands, and will drop any new requests. Test (7) indicates that the element is in a test state. Deferred (8) indicates that the element might be completing commands, but will queue any new requests. Quiesce (9) indicates that the element is enabled but in a restricted mode. Starting (10) indicates that the element is in the process of going to an Enabled state. New requests are queued.

ModelCorrespondence CIM_EnabledLogicalElement.EnabledState
RequestedState uint16 CIM_EnabledLogicalElement
Description RequestedState is 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. Note that when EnabledState is set to 5 ("Not Applicable"), then this property has no meaning. Refer to the EnabledState property description for explanations of the values in the RequestedState enumeration. "Unknown" (0) indicates the last requested state for the element is unknown. Note that the value "No Change" (5) has been deprecated in lieu of indicating the last requested state is "Unknown" (0). If the last requested or desired state is unknown, RequestedState should have the value "Unknown" (0), but may have the value "No Change" (5).Offline (6) indicates that the element has been requested to transition to the Enabled but Offline EnabledState. It should be noted that there are two new values in RequestedState that build on the statuses of EnabledState. These are "Reboot" (10) and "Reset" (11). Reboot refers to doing a "Shut Down" and then moving to an "Enabled" state. Reset indicates that the element is first "Disabled" and then "Enabled". The distinction between requesting "Shut Down" and "Disabled" should also be noted. Shut Down requests an orderly transition to the Disabled state, and might 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 shall be NULL or have the value 12 "Not Applicable".

TimeOfLastStateChange datetime CIM_EnabledLogicalElement
Description The date or time when the EnabledState of the element last changed. If the state of the element has not changed and this property is populated, then it must be set to a 0 interval value. If a state change was requested, but rejected or not yet processed, the property must not be updated.
RequestStateChange method CIM_EnabledLogicalElement
Description Requests that the state of the element be changed to the value specified in the RequestedState parameter. When the requested state change takes place, the EnabledState and RequestedState of the element will be the same. Invoking the RequestStateChange method multiple times could result in earlier requests being overwritten or lost. A return code of 0 shall indicate the state change was successfully initiated. A return code of 3 shall indicate that the state transition cannot complete within the interval specified by the TimeoutPeriod parameter. A return code of 4096 (0x1000) shall indicate the state change was successfully initiated, a ConcreteJob has been created, and its reference returned in the output parameter Job. Any other return code indicates an error condition.

StatusInfo uint16 CIM_LogicalDevice
Deprecated CIM_EnabledLogicalElement.EnabledState
Description The StatusInfo property indicates whether the Logical Device is in an enabled (value = 3), disabled (value = 4) or some other (1) or unknown (2) state. If this property does not apply to the LogicalDevice, the value, 5 ("Not Applicable"), should be used. StatusInfo has been deprecated in lieu of a more clearly named property with additional enumerated values (EnabledState), that is inherited from ManagedSystemElement. If a Device is ("Enabled")(value=3), it has been powered up, and is configured and operational. The Device may or may not be functionally active, depending on whether its Availability (or AdditionalAvailability) indicate that it is ("Running/Full Power")(value=3) or ("Off line") (value=8). In an enabled but offline mode, a Device may be performing out-of-band requests, such as running Diagnostics. If ("Disabled") StatusInfo value=4), a Device can only be "enabled" or powered off. In a personal computer environment, ("Disabled") means that the Device's driver is not available in the stack. In other environments, a Device can be disabled by removing its configuration file. A disabled device is physically present in a System and consuming resources, but can not be communicated with until a load of a driver, a load of a configuration file or some other "enabling" activity has occurred.

Deprecated No value
Description The MaxQuiesceTime property has been deprecated. When evaluating the use of Quiesce, it was determine that this single property is not adequate for describing when a device will automatically exit a quiescent state. In fact, the most likely scenario for a device to exit a quiescent state was determined to be based on the number of outstanding requests queued rather than on a maximum time. This will be re-evaluated and repositioned later. Maximum time in milliseconds, that a Device can run in a "Quiesced" state. A Device's state is defined in its Availability and AdditionalAvailability properties, where "Quiesced" is conveyed by the value 21. What occurs at the end of the time limit is device-specific. The Device may unquiesce, may offline or take other action. A value of 0 indicates that a Device can remain quiesced indefinitely.

SetPowerState method CIM_LogicalDevice
Deprecated CIM_PowerManagementService.SetPowerState
Description Sets the power state of the Device. The use of this method has been deprecated. Instead, use the SetPowerState method in the associated PowerManagementService class.
Reset method CIM_LogicalDevice
Description Requests a reset of the LogicalDevice. The return value should be 0 if the request was successfully executed, 1 if the request is not supported and some other value if an error occurred. In a subclass, the set of possible return codes could be specified, using a ValueMap qualifier on the method. The strings to which the ValueMap contents are 'translated' may also be specified in the subclass as a Values array qualifier.
EnableDevice method CIM_LogicalDevice
Deprecated CIM_EnabledLogicalElement.RequestStateChange
Description The EnableDevice method has been deprecated in lieu of the more general RequestStateChange method that directly overlaps with the functionality provided by this method. Requests that the LogicalDevice be enabled ("Enabled" input parameter = TRUE) or disabled (= FALSE). If successful, the Device's StatusInfo/EnabledState properties should reflect the desired state (enabled/disabled). Note that this method's function overlaps with the RequestedState property. RequestedState was added to the model to maintain a record (i.e., a persisted value) of the last state request. Invoking the EnableDevice method should set the RequestedState property appropriately. The return code should be 0 if the request was successfully executed, 1 if the request is not supported and some other value if an error occurred. In a subclass, the set of possible return codes could be specified, using a ValueMap qualifier on the method. The strings to which the ValueMap contents are 'translated' may also be specified in the subclass as a Values array qualifier.
OnlineDevice method CIM_LogicalDevice
Deprecated CIM_EnabledLogicalElement.RequestStateChange
Description The OnlineDevice method has been deprecated in lieu of the more general RequestStateChange method that directly overlaps with the functionality provided by this method. Requests that the LogicalDevice be brought online ("Online" input parameter = TRUE) or taken offline (= FALSE). "Online" indicates that the Device is ready to accept requests, and is operational and fully functioning. In this case, the Device's Availability property would be set to a value of 3 ("Running/Full Power"). "Offline" indicates that a Device is powered up and operational, but not processing functional requests. In an offline state, a Device may be capable of running diagnostics or generating operational alerts. For example, when the "Offline" button is pushed on a Printer, the Device is no longer available to process print jobs, but could be available for diagnostics or maintenance. If this method is successful, the Device's Availability and AdditionalAvailability properties should reflect the updated status. If a failure occurs trying to bring the Device online or offline, it should remain in its current state. IE, the request, if unsuccessful, should not leave the Device in an indeterminate state. When bringing a Device back "Online", from an "Offline" mode, the Device should be restored to its last "Online" state, if at all possible. Only a Device that has an EnabledState/StatusInfo of "Enabled" and has been configured can be brought online or taken offline. OnlineDevice should return 0 if successful, 1 if the request is not supported at all, 2 if the request is not supported due to the current state of the Device, and some other value if any other error occurred. In a subclass, the set of possible return codes could be specified, using a ValueMap qualifier on the method. The strings to which the ValueMap contents are 'translated' may also be specified in the subclass as a Values array qualifier. Note that this method's function overlaps with the RequestedState property. RequestedState was added to the model to maintain a record (i.e., a persisted value) of the last state request. Invoking the OnlineDevice method should set the RequestedState property appropriately.
QuiesceDevice method CIM_LogicalDevice
Deprecated CIM_EnabledLogicalElement.RequestStateChange
Description The QuiesceDevice method has been deprecated in lieu of the more general RequestStateChange method that directly overlaps with the functionality provided by this method. Requests that the LogicalDevice cleanly cease all current activity ("Quiesce" input parameter = TRUE) or resume activity (= FALSE). For this method to quiesce a Device, that Device should have an Availability (or Additional Availability) of "Running/Full Power" (value=3) and an EnabledStatus/StatusInfo of "Enabled". For example, if quiesced, a Device may then be offlined for diagnostics, or disabled for power off and hot swap. For the method to "unquiesce" a Device, that Device should have an Availability (or AdditionalAvailability) of "Quiesced" (value=21) and an EnabledStatus/StatusInfo of "Enabled". In this case, the Device would be returned to an "Enabled" and "Running/Full Power" status. The method's return code should indicate the success or failure of the quiesce. It should return 0 if successful, 1 if the request is not supported at all, 2 if the request is not supported due to the current state of the Device, and some other value if any other error occurred. In a subclass, the set of possible return codes could be specified, using a ValueMap qualifier on the method. The strings to which the ValueMap contents are 'translated' may also be specified in the subclass as a Values array qualifier.
SaveProperties method CIM_LogicalDevice
Description Requests that the Device capture its current configuration, setup and/or state information in a backing store. The goal would be to use this information at a later time (via the RestoreProperties method), to return a Device to its present "condition". This method may not be supported by all Devices. The method should return 0 if successful, 1 if the request is not supported, and some other value if any other error occurred. In a subclass, the set of possible return codes could be specified, using a ValueMap qualifier on the method. The strings to which the ValueMap contents are 'translated' may also be specified in the subclass as a Values array qualifier.
RestoreProperties method CIM_LogicalDevice
Description Requests that the Device re-establish its configuration, setup and/or state information from a backing store. The intent is to capture this information at an earlier time (via the SaveProperties method), and use it to return a Device to this earlier "condition". This method may not be supported by all Devices. The method should return 0 if successful, 1 if the request is not supported, and some other value if any other error occurred. In a subclass, the set of possible return codes could be specified, using a ValueMap qualifier on the method. The strings to which the ValueMap contents are 'translated' may also be specified in the subclass as a Values array qualifier.

NumberOfBlocks uint64 CIM_StorageExtent
Description 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.
MappingStrings MIF.DMTF|Host Storage|001.5, MIB.IETF|HOST-RESOURCES-MIB.hrStorageSize
ConsumableBlocks uint64 CIM_StorageExtent
Description 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.
IsBasedOnUnderlyingRedundancy boolean CIM_StorageExtent
Description True indicates that the underlying StorageExtent(s) participate in a StorageRedundancyGroup.
SequentialAccess boolean CIM_StorageExtent
Description Boolean set to TRUE if the Storage is sequentially accessed by a MediaAccessDevice. A TapePartition is an example of a sequentially accessed StorageExtent. StorageVolumes, Disk Partitions and LogicalDisks represent randomly accessed Extents.
ExtentStatus uint16[] CIM_StorageExtent
Description StorageExtents have additional status information beyond that captured in the OperationalStatus and other properties, inherited from ManagedSystemElement. This additional information (for example, "Protection Disabled", value=9) is captured in the ExtentStatus property. 'In-Band Access Granted' says that access to data on an extent is granted to some consumer and is only valid when 'Exported' is also set. It is set as a side effect of PrivilegeManagementService.ChangeAccess or equivalent interfaces. 'Imported' indicates that the extent is used in the current system, but known to be managed by some other system. For example, a server imports volumes from a disk array. 'Exported' indicates the extent is meant to be used by some comsumer. A disk array's logical units are exported. Intermediate composite extents may be neither imported nor exported.

ModelCorrespondence CIM_StorageSetting.DeltaReservationGoal, CIM_StorageSetting.DeltaReservationMax, CIM_StorageSetting.DeltaReservationMin
Primordial boolean CIM_StorageExtent
Description 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, (i.e. 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.
NameFormat uint16 CIM_StorageExtent
Description The list here applies to all StorageExtent subclasses. Please look at the Description in each subclass for guidelines on the approriate values for that subclass. Note that any of these formats could apply to a CompositeExtent. Note - this property originally touched on two concepts that are now separated into this property and NameNamespace. Values 2,3,4,5,6, and 8 are retained for backwards compatibility but are deprecated in lieu of the corresponding values in CIM_StorageExtent.NameNamespace. For example, the preferred source for SCSI virtual (RAID) disk names is from Inquiry VPD page 83 response, type 3 identifiers. These will have NameFormat set to 'NAA' and NameNamespace to 'VPD83Type3'. Format of the Name property. Values for extents representing SCSI volumes are (per SCSI SPC-3): 2 = VPD Page 83, NAA IEEE Registered Extended (VPD83NAA6) (DEPRECATED) 3 = VPD Page 83, NAA IEEE Registered (VPD83NAA5) (DEPRECATED) 4 = VPD Page 83, (VPD83Type2) (DEPRECATED) 5 = VPD Page 83, T10 Vendor Identification (VPD83Type1) (DEPRECATED) 6 = VPD Page 83, Vendor Specific (VPD83Type0) (DEPRECATED) 7 = Serial Number/Vendor/Model (SNVM) SNVM is 3 strings representing the vendor name, product name within the vendor namespace, and the serial number within the model namespace. Strings are delimited with a '+'. Spaces may be included and are significant. The serial number is the text representation of the serial number in hexadecimal upper case. This represents the vendor and model ID from SCSI Inquiry data; the vendor field MUST be 8 characters wide and the product field MUST be 16 characters wide. For example, 'ACME____+SUPER DISK______+124437458' (_ is a space character) 8 = Node WWN (for single LUN/controller) (NodeWWN) (DEPRECATED) 9 = NAA as a generic format. See http://standards.ieee.org/regauth/oui/tutorials/fibrecomp_id.html. Formatted as 16 or 32 unseparated uppercase hex characters (2 per binary byte). For example '21000020372D3C73' 10 = EUI as a generic format (EUI64) See http://standards.ieee.org/regauth/oui/tutorials/EUI64.html. Formatted as 16 unseparated uppercase hex characters (2 per binary byte) 11 = T10 vendor identifier format as returned by SCSI Inquiry VPD page 83, identifier type 1. See T10 SPC-3 specification. This is the 8-byte ASCII vendor ID from the T10 registry followed by a vendor specific ASCII identifier; spaces are permitted. For non SCSI volumes, 'SNVM' may be the most appropriate choice. 12 = OS Device Name (for LogicalDisks). See LogicalDisk Name description for details.
