CIM_SCSIProtocolEndpoint Superclass: CIM_ProtocolEndpoint
A SCSIProtocolEndpoint represents the protocol (command) aspects of a logical SCSI port, independent of the connection/transport. SCSIProtocolEndpoint is either directly or indirectly associated to one or more instances of LogicalPort (via PortImplementsEndpoint) depending on the underlying transport. Indirect associations aggregate one or more LogicalPorts using intermediate ProtocolEndpoints (iSCSI, etc). SCSIProtocolEndpoint is also associated to a SCSIProtocolController, representing the SCSI device.

Note: This property is deprecated in lieu of the ProtocolIFType enumeration. This deprecation was done to have better alignment between the IF-MIB of the IETF and this CIM class.
Deprecated description: ProtocolType is an enumeration that provides information to categorize and classify different instances of this class. For most instances, information in this enumeration and the definition of the subclass overlap. However, there are several cases where a specific subclass of ProtocolEndpoint is not required (for example, there is no Fibre Channel subclass of ProtocolEndpoint). Therefore, this property is needed to define the type of Endpoint.

A timeout period that specifies the maximum amount of time that the client expects the transition to the new state to take. The interval format must be used to specify the TimeoutPeriod. A value of 0 or a null parameter indicates that the client has no time requirements for the transition.
If this property does not contain 0 or null and the implementation does not support this parameter, a return code of 'Use Of Timeout Parameter Not Supported' must be returned.

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.
If 0 is returned, then the task completed successfully and the use of ConcreteJob was not required. If 4096 (0x1000) is returned, then the task will take some time to complete, ConcreteJob will be created, and its reference returned in the output parameter Job. Any other return code indicates an error condition.

uint16 RequestedState = 12 ;
RequestedState is an integer enumeration that indicates the last requested or desired state for the element. 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. By default, the RequestedState of the element is 5 ('No Change'). Refer to the EnabledState property description for explanations of the values in the RequestedState enumeration.

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.

A particular instance of EnabledLogicalElement might not support RequestedStateChange. If this occurs, the value 12 ('Not Applicable') is used.

uint16 HealthState ;
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.

string Status ;
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.
MaxLen ( 64 )
string Caption ;
The Caption property is a short textual description (one- line string) of the object.
string ElementName ;
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.
