Class CIM_SCSIInitiatorTargetLogicalUnitPath
extends CIM_InitiatorTargetLogicalUnitPath

An association that models a host driver path to a SCSI logical unit. Each permutation of initiator and target ProtocolEndpoints and logical units is considered a separate path. This class describes end-to-end path behavior such as properties and operations commonly used in multipath management.

NameData TypeValue
AdministrativeOverrideuint16
DescriptionstringAdministrativeOverride allows an administrator to select a single path, force all I/O to this path, and disables load balancing. The steady-state value is 'No override in effect'. When an administrator sets an override for a particular path, that path's AdministrativeOverride is set to 'Overridding' and all other paths to same logical unit are assigned a value of 'Overridden'. This property is changed using the OverridePath method in SCSIPathConfigurationService.

ValuesstringOverriding, Overridden, No override in effect
AdministrativeWeightuint32
DescriptionstringA value assigned by an administrator specifying a preference to assign to a path. The drivers will actively use all available paths with the highest weight. This allows an administrator to assign a subset of available paths for load balanced access and reserve the others as backup paths. For symmetric access devices, all paths are considered 'available'. For asymmetric access devices, all paths in active target port groups are considered available.

LogicalUnitNumberuint16
DescriptionstringThe SCSI Logical Unit Number. This is the unit number with values below 16,384 used in management applications. It is not the full SCSI SAM 8-byte logical unit number structure. Using the terminology from the T10 SCSI specifications, this is the LU number with a value between 0 and 255 using the Peripheral device addressing method with Bus Identifier zero or a LU number between 0 and 16,383 using the Flat space (AKA volume set) addressing method.

OSDeviceNamestring
DescriptionstringThe OS Device Name for this path. Only applicable if the ExposedPathDeviceFiles property is true in the instance of SCSIMultipathConfigurationCapabilities associated with the LogicalDevice/RedundancySet this instance is a member of.
