CIM_InitiatorTargetLogicalUnitPath
An association that models a host driver path to a logical unit. Each permutation of initiator and target ProtocolEndpoints and logical units is considered a separate path.

Parameters (local in grey)
Key
CIM_ProtocolEndpoint REF Target ;
A target endpoint.
ValueMap { "0" , "2" , "3" , "4" , "5" , "6" , "7" , "8" , "9" }
Values { "Unknown" , "Active" , "Passive" , "Disabled" , "Path Error" , "Logical Unit Error" , "Reserved" , "Removed" , "Transitioning" }
MappingStrings { "MP_API.SNIA|MP_PATH_LOGICAL_UNIT_PROPERTIES|pathState" }
Write
uint32 State ;
The state of this path. Values are defined as follows:
Unknown - the path is unavailable,but the cause is not known.
Active - The path is okay and active.
Passive - The path is okay, but is associated with a target port of target port group in standby access state. Only applies to devices with asymmetric access.
Disabled - The path is disabled by administrative request (DisablePathLU).
Path Error - The path is unusable due to an error on this path and no SCSI status was received.
Logical Unit Error - A SCSI status was received for an I/O through this path indicating a logical unit error.
Reserved - The path is unavailable due to a reservation.
Removed - The path is unavailable because the OS or drivers marked the pathunusable.
Transitioning - the path is transitioning between two valid states.
The only valid values a client can specify are Disabled and Active. All other states are determined by the underlying implementation; attempts to set them should be given an error response.
Key
CIM_ProtocolEndpoint REF Initiator ;
An initiator endpoint.
Key
CIM_LogicalDevice REF LogicalUnit ;
A subclass of LogicalDevice representing a Logical Unit (such as StorageVolume or TapeDrive). Refer to the Logical Unit Number section of ANSI INCITS 402-2005 , the SCSI-3 Architecture Model (SAM).
