Shows a virtual disk to an initiator.

This operation is also known as "exposing" or "unmasking" a virtual disk.


UInt32 Show(
  [in]  String              TargetPortAddresses[],
  [in]  String              InitiatorAddress,
  [in]  UInt16              HostType,
  [in]  Boolean             RunAsJob,
  [out] MSFT_StorageJob REF CreatedStorageJob,
  [out] String              ExtendedStatus


TargetPortAddresses [in]

An array of target port addresses from which the virtual disk should be shown.

This parameter is required and cannot be NULL.

InitiatorAddress [in]

The address of the initiator to which the virtual disk should be shown.

This parameter is required and cannot be NULL.

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.

ExtendedStatus [out]

A string that contains an embedded MSFT_StorageExtendedStatus object.

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