  • 项目

[Removable Storage Manager is no longer available as of Windows 7 and Windows Server 2008 R2.]

The DisableNtmsObject function disables the specified RSM object.

Syntax

DWORD DisableNtmsObject(
  __in  HANDLE hSession,
  __in  DWORD dwType,
  __in  LPNTMS_GUID lpObjectId
);

Parameters

  • hSession [in]
    Handle to the session returned by the OpenNtmsSession function.

  • dwType [in]
    RSM object type. This parameter can be one of the following values from the NtmsObjectsTypes enumeration type.

    Value Meaning
    NTMS_DRIVE

    Drive
    NTMS_LIBRARY

    Library
    NTMS_PHYSICAL_MEDIA

    Physical media (tape, optical disk, CD, or magnetic cartridge)

     

  • lpObjectId [in]
    Unique identifier of the RSM object.

Return Value

This function returns one of the following values.

Value Meaning
ERROR_ACCESS_DENIED

NTMS_MODIFY_ACCESS to the library containing the object is denied. Other security errors are possible, but indicate a security subsystem error.

Windows XP/2000:  NTMS_CONTROL_ACCESS to the library containing the object is denied. Other security errors are possible, but indicate a security subsystem error.
ERROR_DATABASE_FAILURE

The database is inaccessible or damaged.
ERROR_INVALID_HANDLE

The session handle is missing or is not valid.
ERROR_INVALID_PARAMETER

An object ID is missing or the object type is not valid. (The object type is not valid if it is not NTMS_LIBRARY, NTMS_DRIVE, or NTMS_PHYSICAL_MEDIA.)
ERROR_INVALID_STATE

The object is already disabled.
ERROR_LIBRARY_OFFLINE

The library ID refers to an off-line library that cannot be enabled or disabled.
ERROR_OBJECT_NOT_FOUND

The object is not valid.
ERROR_SUCCESS

The disable is queued.

 

Remarks

The DisableNtmsObject function queues a disable command for the specified object. The function returns successfully when the command is queued. If RSM is busy, the command can take some time to complete. When the medium is disabled, RSM renders all of the media's sides and associated logical media unavailable. All requests to disabled media return errors.

To remove a drive or media changer from service the drive or media changer must first be disabled.

All objects contained by a disabled object are also disabled. For example, disabling a piece of physical media disables all sides. Whenever possible, when a drive is disabled, the medium in the drive is removed and placed in its slot.
