Explanation
Where
text is:
UNIT TYPE STATUS VOLSER VOLSTATE
uuuu type status volser vvvvvvvvvv
UNIT TYPE UNIT TYPE ...
uuuu type uuuu uuuu ...
This
message appears in response to a DISPLAY U command. It can appear
in either of two formats, depending on whether the command is DISPLAY
U or D U,,ONLINE, or DISPLAY U,,OFFLINE.
The message that displays
in response to DISPLAY U or D U,,ONLINE has the following format:
UNIT TYPE STATUS VOLSER VOLSTATE
uuuu type status volser vvvvvvvvvv
The
message that displays in response to DISPLAY U,,OFFLINE has up to
seven instances of UNIT and TYPE, followed by device
information.
In the message text:
- UNIT
- The unit for which you are accessing information
- TYPE
- Refers to the following devices:
- CTC adapters
- DASD
- Graphic devices
- Magnetic tape device
- Communication equipment
- Unit record devices
Devices appear as specified through HCD (for TP devices,
only the control unit is shown.)
The following device types
might appear in the TYPE field:
- type
- Device type, such as ‘3380’
- 3330-1
- 3330V
Note: Certain Device Types in the same Device Class may display
as all the same Device Type. This behavior is discussed in APAR OY58396.
- xxxS
- where xxx represents the first three digits
of device type (for example, ‘348’ for a 3480 or ‘349’
for a 3490) and ‘S’ means the device has a cartridge stack
loader.
- xxxL | xxxM
- where xxx represents the first three digits
of a device type (for example, ‘348’ for a 3480 or ‘349’
for a 3490). ‘L’ means the device is ATL resident, and ‘M’
means the device is MTL resident.
Note: If a device is both a library
device and has a cartridge stack loader, the L or M designation takes
precedence over the S designation.
- UND
- where the device is not known.
- STATUS
- The status of the device, which can be a combination of the
following. For example, if A-BSY appears in the message, the device
is both allocated and busy.
- A
- Allocated
- AS
- Automatically switchable
- BOX
- Hardware error
- BSY
- Busy
- C
- Console
- F
- Offline. This is used when a combination of offline and some other
status value needs to be displayed; for example, F-NRD.
- L
- The release on a device is pending and reserve may or may not
have occurred.
- M
- A device managed by a device manager, such as JES3 or a non-IBM
tape management subsystem
- MTP
- Mount pending
- NRD
- Not ready
- O
- Online
- OFFLINE
- This is used when the only status value that needs to be displayed
is OFFLINE.
- P
- Reserve pending
- PND
- Offline pending
- PO
- Offline pending, and also not ready. This status value is displayed
only if NRD is also displayed on the status line.
- PUL
- Unload pending
- R
- Reserved, shared DASD or exclusively-assigned device
- RAL
- Restricted to allocation
- S
- SYSRES
- SPD
- Channel program is temporarily suspended while the system is using
it.
- SYS
- Allocated to system
- UNAVL
- The device has been marked unavailable for allocation by the VARY
xxxx,UNAVAIL operator command.
Note: A MOUNT pending designation for a given device
(shown as ‘MTP’ in the message text) does not indicate
that a volume should be mounted on the device in the following cases:
- No MOUNT message has yet been issued for the device (in this case
the device is also designated allocated - shown as ‘A’
in the message text).
- One or more MOUNT messages were issued for the device but the
job(s) for which the messages were issued has been cancelled.
In the first case no action is necessary because a MOUNT
message may or may not be issued. In the second case no action is
necessary, but issuing an UNLOAD command to the device clears the
mount-pending condition.
- VOLSER
- The volume serial number of the device.
- VOLSTATE
- How the device is to be used, either for public (PUB) or private
(PRIV) or storage (STRG) use and whether the device is reserved (RSERV)
or removable (REMOV) or permanently resident (RSDNT).
- idr
- An identifier used with the CONTROL C,D command to cancel status
displays:
- Written on printer consoles
- Displayed inline (that is, not in a display area) on a display
console
This identifier does not appear when the display is presented
in a display area on a display console.
System action
The system continues processing.
