A class derived from SystemSpecificCollection that models SCSI Target Port Groups. SCSITargetPortGroup is part of the model for devices with asymmetric access to logical units - access is optimized for a subset of target ports. SCSITargetPortGroup is aggregated to SCSIProtocolEndpoints that expose a common ValueMap { 2, 3, 4, 5, 6 }, Values { Active/Optimized, Active/Non-optimized, StandBy, Unavailable, Transitioning }, access state for a set of associated logical Units (modeled by various subclasses of LogicalDevice). SCSITargetPortGroups only apply to target devices with asymmetric multipath access and not to devices with symmetric (or single path) access. | Qualifiers:Version ( "2.10.0" ) Experimental UMLPackagePath ( "CIM::Device::StorageDevices" ) | Parameters (local in grey) | | MappingStrings { "MP_API.SNIA|MP_TARGET_PORT_PROPERTIES|explicitFailover" } boolean ExplicitFailover ; True indicates that the underlying implementation provides an interface allowing drivers to explicitly request activation of a target port group - either through the SCSI SET TARGET PORT GROUP or a proprietary command. | MappingStrings { "MP_API.SNIA|MP_TARGET_PORT_PROPERTIES|tpgID" , "SPC.INCITS-T10 | Target Port Group Descriptor | Target Port " "Group" , "SPC.INCITS-T10 | Inquiry VPD page 0x85 | Target Port Group" } uint16 Identifier ; An integer identifier for the target port group. This corresponds to the TARGET PORT GROUP field in the REPORT TARGET PORT GROUPS response and the TARGET PORT GROUP field in an INQUIRY VPD page 85 response, type 5h identifier. | MappingStrings { "MP_API.SNIA|MP_TARGET_PORT_PROPERTIES|supportsLuAssignment" } boolean SupportsLuAssignment ; True indicates that the underlying implementation provides an interface allowing the administrator to reassign logical units to target port groups. | ValueMap { "2" , "3" , "4" , "5" , "6" } Values { "Active/Optimized" , "Active/Non-optimized" , "StandBy" , "Unavailable" , "Transitioning" } MappingStrings { "SPC.INCITS-T10 |Asymmetric Access State" , "MP_API.SNIA|MP_ACCESS_STATE_TYPE" } uint16 AccessState ; Access to all associated logical units through all aggregated ports share this access state. Access to the Logical Units through other ports is specified by the access state of those port's target port group. | MappingStrings { "MP_API.SNIA|MP_TARGET_PORT_PROPERTIES|preferredLUPath" , "SPC.INCITS-T10 | Target Port Group Descriptor | PREF" } boolean Preferred ; True indicates that the target device indicates that access to the associated logical units through the ports in this target port group is preferred over access through other ports. This may correspond to the PREF bit in the SCSI TARGET PORT GROUP descriptor or an equivalent vendor-specific interface. | Key string InstanceID ; Within the scope of the instantiating Namespace, InstanceID opaquely and uniquely identifies an instance of this class. 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 unique name. It can be a copyrighted, trademarked, or otherwise unique name that is owned by the business entity that is creating or defining the InstanceID. Or, it could be a registered ID that is 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 re-used to identify different underlying (real-world) elements. If the above 'preferred' algorithm is not used, the defining entity must ensure that the resulting InstanceID is not re-used as any of InstanceIDs produced by this or other providers for the NameSpace of this instance. For DMTF-defined instances, the 'preferred' algorithm must be used with the <OrgID> set to 'CIM'. | 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. | MaxLen ( 64 ) string Caption ; The Caption property is a short textual description (one- line string) of the object. | string Description ; The Description property provides a textual description of the object. |
