CreateMaskingSet method of the MSFT_StorageSubSystem class

Creates a new masking set.

A masking set is a logical grouping of virtual disks, target ports, and initiators for the purpose of showing virtual disks to host computers

Syntax


UInt32 CreateMaskingSet(
  [in]   String FriendlyName,
  [in]   String VirtualDiskNames[],
  [in]   UInt16 DeviceAccesses[],
  [in]   String DeviceNumbers[],
  [in]   String TargetPortAddresses[],
  [in]   String InitiatorAddresses[],
  [in]   UInt16 HostType,
  [in]   Boolean RunAsJob,
  [out]  MSFT_StorageJob REF CreatedStorageJob,
  [out]  String CreatedMaskingSet,
  [out]  String ExtendedStatus
);

Parameters

FriendlyName [in]

The friendly name for the masking set.

Friendly names are expected to be descriptive, but they are not required to be unique.

This parameter is required and cannot be NULL.

VirtualDiskNames [in]

The list of virtual disks to show to the initiators in the masking set. Each disk must be specified by the identifier that is stored in the Name property of its MSFT_VirtualDisk object

This parameter has a 1:1 mapping with the DeviceAccesses parameter. Both arrays must be the same length, and the elements must be arranged in the same order.

DeviceAccesses [in]

The level of access that the initiator should have to each virtual disk specified in the VirtualDiskNames parameter. This parameter has a 1:1 mapping with the VirtualDiskNames parameter. Both arrays must be the same length, and the elements must be arranged in the same order.

Unknown (0)
Read Write (2)
Read-Only (3)
No Access (4)
DeviceNumbers [in]

Specifies the order in which the virtual disks should be shown to initiators. This capability is only available if the storage subsystem's MaskingClientSelectableDeviceNumbers property is TRUE. If specified, this parameter must have a 1:1 mapping with the VirtualDiskNames parameter.

TargetPortAddresses [in]

The target ports to use when showing the virtual disks to initiators. The number of target ports that can be specified depends on the subsystem's MaskingPortsPerView property. If MaskingPortsPerView is All target ports share the same view, this parameter is ignored, and all target ports on the system are associated with this masking set.

InitiatorAddresses [in]

The initiators to which the virtual disks should be shown. If the subsystem's MaskingOneInitiatorIdPerView property is TRUE, only one initiator can be specified for this masking set. The list of valid initiator address formats is specified by the subsystem's MaskingValidInitiatorIdTypes property.

HostType [in]

The host operating system or other host environmental factors that may influence the behavior that the storage system should have when showing a virtual disk to an initiator.

RunAsJob [in]

If TRUE, this method uses the CreatedStorageJob parameter when the request is taking a long time to service. If a storage job has been created to track the operation, this method will return Method Parameters Checked - Job Started.

Note  Even if RunAsJob is TRUE, this method can still return a result if it has finished in sufficient time.

If FALSE or NULL, this method will follow default WMI asynchronous behavior as determined by the client's method for invocation. In other words, it is synchronous unless requested otherwise.

CreatedStorageJob [out]

If RunAsJob is set to TRUE and this method takes a long time to execute, this parameter receives a reference to the storage job object that is used to track the long-running operation.

CreatedMaskingSet [out]

If the masking set is created successfully, this parameter receives a string that contains an embedded MSFT_MaskingSet object.

ExtendedStatus [out]

A string that contains an embedded MSFT_StorageExtendedStatus object.

This parameter allows the storage provider to return extended (implementation-specific) error information.

Not Supported (1)
Unspecified Error (2)
Timeout (3)
