Class CIM_SCSIMultipathSettings
extends CIM_SettingData

A class derived from CIM_SettingData describing settings related to management of multiple paths to SCSI devices. It is associated to one of more instances of subclasses of LogicalDevice that represent SCSI logical units. If a LogicalDevice instance is associated to an instance of SCSIPathConfigurationService and is not associated to an instance of this class, the the default values for properties below and the polling values from the associated CIM_SCSIMultipathConfigurationCapabilities instance apply.

NameData TypeDefault ValueQualifiers
NameData TypeValue
Asymmetricbooleanfalse
DescriptionstringA boolean indicating whether the associated logical unit has asymmetric multipath access. If Asymmetric is true, then there MUST be a SCSITargetPortGroup instance associated to the LogicalDevice.
MappingStringsstringMP_API.SNIA|MP_MULTIPATH_LOGICAL_UNIT_PROPERTIES|asymmetric
Writebooleantrue
AutoFailbackEnableduint164
DescriptionstringThe auto-failback setting for the associated logical units. Either enabled, disabled, or all associated logical units follow the service-wide setting from the capabilities class associated with the appropriate service.
MappingStringsstringMP_API.SNIA|MP_MULTIPATH_LOGICAL_UNIT_PROPERTIES|autoFailbackEnabled
ModelCorrespondencestringCIM_SCSIMultipathConfigurationCapabilities.AutoFailbackEnabled
ValueMapstring2, 3, 4
ValuesstringEnabled for the associated logical units, Disabled for the associated logical units, The associated logical units use the service-wide setting
Writebooleantrue
CurrentLoadBalanceTypeuint167
DescriptionstringThe load balance type for the associated logical unit.
MappingStringsstringMP_API.SNIA|MP_MULTIPATH_LOGICAL_UNIT_PROPERTIES|currentLoadBalanceType
ModelCorrespondencestringCIM_SCSIMultipathSettings.OtherCurrentLoadBalanceType
ValueMapstring0, 1, 2, 3, 4, 5, 6, 7
ValuesstringUnknown, Other, No Load Balancing, Round Robin, Least Blocks, Least IO, Product Specific, Service Wide Default
Writebooleantrue
CurrentPollingRateuint32
DescriptionstringThe current polling rate (in seconds) for auto-failback. This cannot exceed PollingRateMax. If this property and the service-wide Capabilities instance CurrentPollingRate are non-zero, this value has precedence for the associated logical units. The instrumentation should not instantiate this property if the value from CIM_SCSIMultipathConfigurationCapabilities is used for the associated logical units.
MappingStringsstringMP_API.SNIA|MP_MULTIPATH_LOGICAL_UNIT_PROPERTIES|currentPollingRate
ModelCorrespondencestringCIM_SCSIMultipathConfigurationCapabilities.CurrentPollingRate
Writebooleantrue
OtherCurrentLoadBalanceTypestring
DescriptionstringA string describing the current load balance algorithm if CurrentLoadBalanceType is 1 ('Other'). This string MUST be identical to one of the strings from CIM_SCSIMultipathConfigurationCapabilities OtherSupportedLoadBalanceAlgorithmNames.
MappingStringsstringMP_API.SNIA|MP_MULTIPATH_LOGICAL_UNIT_PROPERTIES|currentLoadBalanceType
ModelCorrespondencestringCIM_SCSIMultipathConfigurationCapabilities.OtherSupportedLoadBalanceAlgorithmNames, CIM_SCSIMultipathSettings.CurrentLoadBalanceType
Writebooleantrue
PollingRateMaxuint32
DescriptionstringThe maximum polling rate (in seconds) supported by the driver if different from the service-wide max from the capabilities instance. Zero (0) indicates the driver either does not poll for autofailback or has not provided an interface to set the polling rate for multipath logical units. If this property and the service PollingRateMax are non-zero, this value has precedence for the associate logical units. The instrumentation should not instantiate this property if the value from CIM_SCSIMultipathConfigurationCapabilities is used for the associated logical units.
