Use the MVS LIBRARY DISPDRV command to display the status of any
of the following combination of drives: - All tape drives in a tape library
- A single tape drive
- A number of tape drives
- A range of tape drives
You can also use the MVS DISPLAY UNIT command, the MVS DEVSERV
command or the JES3 *I,D command to display the status of tape drives
within a tape library. See z/OS MVS System Commands for additional information on the specific MVS
command.
The syntax of the LIBRARY DISPDRV command to display tape drive
status is as follows:
>>-+-LIBRARY-+--+-DISPDRV-+--,---------------------------------->
'-LI------' '-DD------'
>--+-library_name--------------------+--+----------------+-----><
+-device_number-------------------+ '-,L=-+-a------+-'
+-device_number,number_of_devices-+ +-name---+
'-device_number1-device_number2---' '-name-a-'
- DISPDRV | DD
- Specifies a request to display tape drive status.
- library_name
- Specifies the name of the tape library whose tape drives are to
be displayed. However, the maximum number of tape drives that is displayed
does not exceed 2048.
- device_number
- Specifies the MVS tape device number to be displayed.
- number_of_devices
- Specifies the number of devices to be displayed. However, the
maximum number of tape drives that is displayed does not exceed 2048.
- device_number1
- Specifies the first MVS tape device number to be displayed.
- device_number2
- Specifies the last MVS tape device number to be displayed. However,
the maximum number of tape drives that is displayed does not exceed
2048.
- ,L={a | name | name-a}
- Specifies where to display the results of the inquiry: the display
area (L=a), the console name (L=name), or both the console
name and the display area (L=name-a). The name parameter can be an alphanumeric character string.
To display tape drive status, enter the following command: LIBRARY DISPDRV,(library_name)

- 3400
- This is a 3400 magnetic tape drive.
- UNKNOWN
- Tape device is not recognized.
Whether a device defined through HCD is real or
emulated is not determined until successful communication to the device
has been made. Until successful communication has been made, the device
type displayed will reflect the device type defined through HCD. Thus
for emulated devices, beginning with the 3590 Model E, the device
type displayed reflects the emulated device type defined through HCD
rather than the real underlying device type (3590-E, 3590-H, 3592-J,
3592-2, 3592-2E 3592-3E, and 3592-4E). Once successful communication
to the device has been established, the device type displayed will
reflect the real underlying device type.
Also, on system levels
that support the emulated device type defined through HCD, but do
not support the real underlying device type (such as the 3590 Model
E, 3590 Model H, 3592 Model J, 3592 Model E05, 3592 Model E06, or
3592 Model E07), the device type displayed reflects the emulated device
type that is defined through HCD.
- libname
- Name or ID of the library in which the tape drive resides. For
a stand-alone tape drive (nonlibrary-resident drive), this field contains
‘--N/A--’.
The library name is stored during OAM initialization
(or during library VARY processing) for those devices in the library
returned by device services. If, after this process, devices in a
subsystem are subsequently varied online, the library name displayed
may reflect the LIBRARY-ID. As long as the correct library name or
library ID is displayed, having the LIBRARY-ID appear in the display
should not pose a problem. See Creating the hardware configuration for more information.
