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 has the following format: 
UNIT         TYPE       STATUS         VOLSER            VOLSTATE       SS
uuuu         type       status         volser            vvvvvvvvvv        n
The message that displays in response to DISPLAY U,,OFFLINE has up to seven instances of UNIT and TYPE information:
UNIT  TYPE  UNIT  TYPE  UNIT  TYPE  UNIT  TYPE  UNIT  TYPE

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
RO
Device can only be accessed in read-only mode from this host system.
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).
SS
A one digit device Subchannel Set ID.
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.
