3.2.4.4.1.41 IVolumeClient::ReAttachDisk (Opnum 47)

  • Article

The ReAttachDisk method reattaches the specified dynamic disk, bringing the volumes of the disk back online after reconnecting the disk device to the server. This is a synchronous task.<152>

 HRESULT ReAttachDisk(
   [in] LdmObjectId diskId,
   [in] hyper diskLastKnownState,
   [out] TASK_INFO* tinfo
 );

diskId: Specifies the OID of the disk to reattach.

diskLastKnownState: Disk's last known modification sequence number.

tinfo: Pointer to a TASK_INFO structure that the client can use to track the request's progress.

Return Values: The method MUST return 0 or a nonerror HRESULT on success, or an implementation-specific nonzero error code on failure (as specified in [MS-ERREF]; see also section 2.2.1 for HRESULT values predefined by the Disk Management Remote Protocol).

Upon receiving this message, the server MUST validate parameters:

  • Verify that the dynamic disk specified by diskId is in the list of storage objects, and check whether diskLastKnownState matches the LastKnownState field of the object.

  • Verify that tinfo is not NULL.

If parameter validation fails, the server MUST fail the operation immediately, returning an appropriate error as its response to the client.

Otherwise, the server MUST process the message as follows:

  1. Bring the dynamic disk specified by diskId online:

    • Mark the disk as being present.

    • Bring any dynamic volumes that reside on the disk online.

  2. Wait for the operation to either succeed or fail.

  3. Fill in the tinfo output parameter.

    TASK_INFO member

    Required for this operation

    TASK_INFO::id

    Required.

    TASK_INFO::storageId

    Not required.

    TASK_INFO::createTime

    Not required.<153>

    TASK_INFO::clientID

    Not required.<154>

    TASK_INFO::percentComplete

    Required for any task that returns REQ_IN_PROGRESS.

    TASK_INFO::status

    Required.

    TASK_INFO::type

    Required if PercentageComplete is being used.

    TASK_INFO::error

    Required.

    TASK_INFO::tflag

    Not required.<155>

  4. Return a response to the client containing tinfo and the status of the operation.

  5. Send the task completion notification.

If the operation is successful, the server MUST make the following changes to the list of storage objects before returning the response:

  1. Modify the disk object to account for the change in status.

  2. Modify the volume objects that reside on the disk to account for the change in status.

  3. Modify drive letter objects that correspond to the volumes brought online to mark them as free.

  4. Create file system objects for the volumes brought online (if the volumes are formatted with file systems).
