The NTMS_PMIDINFORMATION structure defines the properties specific to a physical media object.

Syntax

typedef struct _NTMS_PMIDINFORMATIONA {
  NTMS_GUID CurrentLibrary;
  NTMS_GUID MediaPool;
  NTMS_GUID Location;
  DWORD     LocationType;
  NTMS_GUID MediaType;
  NTMS_GUID HomeSlot;
  CHAR      szBarCode[NTMS_BARCODE_LENGTH];
  DWORD     BarCodeState;
  CHAR      szSequenceNumber[NTMS_SEQUENCE_LENGTH];
  DWORD     MediaState;
  DWORD     dwNumberOfPartitions;
  DWORD     dwMediaTypeCode;
  DWORD     dwDensityCode;
  NTMS_GUID MountedPartition;
} NTMS_PMIDINFORMATIONA;

Members

CurrentLibrary

Unique ID of the library in which the media is contained.

MediaPool

Unique ID of the media pool to which the media is assigned.

Location

Unique ID of the physical location object for the media.

LocationType

Current location type of a piece of physical media. The value of this member can be set to NTMS_STORAGESLOT, NTMS_DRIVE, NTMS_IEPORT. (Offline media are in slots.)

MediaType

Unique ID of a media type object.

HomeSlot

Unique ID of the library storage slot in which media is stored.

szBarCode[NTMS_BARCODE_LENGTH]

String that matches the bar-code value on a bar-code label of a piece of physical media.

BarCodeState

Current state of the bar code. This can be one of the following values.

Value Meaning
NTMS_BARCODESTATE_OK
 The media has a bar code and it is readable.
NTMS_BARCODESTATE_UNREADABLE
 The media either does not have a bar code or the bar code is unreadable.

szSequenceNumber[NTMS_SEQUENCE_LENGTH]

Sequential number assigned to the specified medium as a human-readable value that must be transcribed by a user on the medium so that the medium can be located in an offline library.

MediaState

Current state for the piece of physical media. This can be one of the following values.

Value Meaning
NTMS_MEDIASTATE_IDLE
 The media is in a slot in the library, in a drive dismounted, or in an offline library.
NTMS_MEDIASTATE_INUSE
 The media is marked as in use as soon as a request for an operation is successfully made to RSM.
NTMS_MEDIASTATE_LOADED
 The state of the media when RSM has determined that the media is available for reading and writing.
NTMS_MEDIASTATE_MOUNTED
 The state of a piece of physical media when the media is placed in a drive.
NTMS_MEDIASTATE_OP_ERROR
 The physical media is in an error state that is recoverable. No operator intervention is required.
NTMS_MEDIASTATE_UNLOADED
 The state of the media when it is ready to be removed from a drive. The drive state, DISMOUNTABLE, also indicates that a drive can be removed at any time.
NTMS_MEDIASTATE_OPREQ
 Media is waiting for operator request.

dwNumberOfPartitions

Number of sides on the medium.

dwMediaTypeCode

SCSI media type code.

dwDensityCode

SCSI density code.

MountedPartition

Globally unique ID of the side of the media that is currently mounted.

Remarks

The NTMS_PMIDINFORMATION structure is included in the NTMS_OBJECTINFORMATION structure.

Note

The ntmsapi.h header defines NTMS_PMIDINFORMATION as an alias that automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that is not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
