| CanOverridePaths | boolean | false |
| Description | string | The capability of the driver to support the SetOverridePath and CancelOverridePaths methods. True if the implementation supports path overrides. |
| MappingStrings | string | MP_API.SNIA|MP_PLUGIN_PROPERTIES|canOverridePaths |
| ModelCorrespondence | string | CIM_SCSIPathConfigurationService.SetOverridePath |
| CanSetTPGAccess | boolean | false |
| Description | string | The capability of the driver to support the SetTPGAccess method. True if the implementation supports activating target port groups. |
| MappingStrings | string | MP_API.SNIA|MP_PLUGIN_PROPERTIES|canSetTPGAccess |
| ModelCorrespondence | string | CIM_SCSIPathConfigurationService.SetTPGAccess |
| CurrentPollingRate | uint32 | |
| Description | string | The current rate in seconds. Only valid when pollingRateMax is greater than 0 and canAutoFailback are true. |

| Write | boolean | true |
| DefaultLoadBalanceType | uint16 | |
| Description | string | The load balance types supported by the driver if not overridden by an administrative action. |

| ValueMap | string | 0, 1, 2, 3, 4, 5, 6 |
| Values | string | Unknown, Other, No Load Balancing, Round Robin, Least Blocks, Least IO, Product Specific |
| Write | boolean | true |
| DeviceNameFilespace | string | |
| Description | string | A string representing the primary file names the driver uses for multipath logical units, if those filenames do not match the names in Logical Unit osDeviceName as documented in Appendix A of the SNIA MP API specification. The name is expressing in the following format:
'*' represents one or more alphanumeric characters
'#' represents a string of consecutive digits
'%' represents a string of hexadecimal digits
backslash is an escape character for literal presentation of *, #, or %. Any other character is interpreted literally. For example, '/dev/vx/dmp/*'. If the multipath driver creates multipath logical unit device file names in the same namespace as the OS then this property should be left null. |
| MappingStrings | string | MP_API.SNIA|MP_PLUGIN_PROPERTIES|deviceNameFilespace |
| MaxLen | uint32 | 256 |
| ExposesPathDeviceFiles | boolean | |
| Description | string | False if the MP drivers assure only a single device file name (e.g. /dev/dsk/...) exists for each MP device. True if the implementation exposes (or leaves exposed) device files for the individual paths encapsulated by the multipath device file. This is typically true for MP drivers that sit near the top of the driver stack and false for transport drivers at the bottom of the stack. |
| MappingStrings | string | MP_API.SNIA|Plugin Properties|exposesPathDeviceFiles |
| MaximumWeight | uint32 | |
| Description | string | Describes the range of administer settable path weights supported by the driver. A driver with no path preference capabilities should set this property to zero. A driver with the ability to enable/disable paths should set this property to 1. Drivers with more weight settings can set the property appropriately. |
| MappingStrings | string | MP_API.SNIA|MP_PLUGIN_PROPERTIES|maximumWeight |
| OnlySupportsSpecifiedProducts | boolean | false |
| Description | string | True if the only supported device types are those described in aggregated CIM_Product instances as described in the description of SupportedLoadBalanceTypes. |
| MappingStrings | string | MP_API.SNIA|MP_PLUGIN_PROPERTIES|deviceNameFilespace |
| ModelCorrespondence | string | CIM_SCSIMultipathConfigurationCapabilities.SupportedLoadBalanceTypes |
| PollingRateMax | uint32 | |
| Description | string | The maximum polling rate (in seconds) supported by the driver. A value of zero indicates the driver/plugin does not support polling. This maximum applies to both BadPathPollingRate and InactivePathPollingRate. |
| MappingStrings | string | MP_API.SNIA|MP_PLUGIN_PROPERTIES|pollingRateMax |
| OtherSupportedLoadBalanceAlgorithmNames | string[] | |
| ArrayType | string | Indexed |
| Description | string | When the corresponding array entry in SupportedLoadBalanceTypes[] is 'Other', this entry provides a string describing the load balancing algorithm. When the corresponding array entry in SupportedLoadBalanceTypes[] is 'Product Specific', this entry provides a string specifying the SCSI vendor/product/revision and must be formatted as exactly 28 ASCII characters - 8 for vendor, 16 for product, and 4 for revision (see SCSI SPC Inquiry response) |
