QUERY ALL
You see responses like the following if real DASDs are attached to the system for
access as user minidisks or for system paging, spooling, or temporary disk space.
DASD 0280 CP SYSTEM XAUSR1 49
DASD 0281 CP SYSTEM XAUSR2 24
DASD 0282 CP SYSTEM XAUSR3 49
DASD 0283 CP SYSTEM XAUSR4 34
DASD 0284 CP SYSTEM XAUSR5 42
DASD 0285 CP SYSTEM XAUSR6 20
DASD 0A01 CP OWNED ESAP01 3
DASD 0A02 CP OWNED ESAP02 1
DASD 0A03 CP OWNED ESAP03 1
DASD 0A04 CP OWNED ESAP04 1
DASD 0A05 CP OWNED ESAP05 1
DASD 0C08 CP SYSTEM ESAP7 1
DASD 0C09 CP SYSTEM ESAP6 1
DASD 1800 CP SYSTEM USPK1 4
DASD 1801 CP SYSTEM USPK2 2
The first number listed (for example, 0280) is the real device number of the DASD.
SYSTEM indicates the device is allocated to the system for use as users’ minidisks.
OWNED indicates the device is used by the system for paging and spooling activity.
XAUSR1, ESAP01, and the rest are volume labels of the devices. The last number
(for example, 49) indicates the number of links to minidisks contained on the
volume.
The following response is also displayed if real DASDs are attached to the system
for access as user minidisks or for system paging, spooling, or temporary disk
space. This response is longer than the response above because the device may
be reserved (shared option is on), it may have a reserve pending, or it is currently
reserved.

DASD 181B CP OWNED ESAP2F RESERVE PENDING FOR USER DAVID
DASD 181C CP OWNED ESAP30 RESERVED BY SYSTEM
If a DASD is dedicated to a user, you see a message like this:
DASD 0820 ATTACHED TO OLIVER 01FC R/0 XAUSR4
This means that the DASD at the real device number 0820 is attached to OLIVER’s
virtual machine as the virtual device 01FC. The DASD’s volume identifier is
XAUSR4. R/O means the user OLIVER has read-only access to the DASD. R/O
might also read R/W, which means the user has read-write access. ATTACHED
may be replaced with BOX/ATTC, which means that although the device is
dedicated to a user, it is unavailable (usually because of a hardware condition).
Responses from Real Graphic Display Devices:
If a real graphic display is dedicated to a virtual machine, you see something like
this:
GRAF 0BCD ATTACHED TO OLIVER 0010
674 z/VM: CP Commands and Utilities Reference
This message means the graphic display device at the real device number 0BCD is
attached to OLIVER’s virtual machine as the virtual device 0010. ATTACHED may
be replaced with BOX/ATTC, which means that although the device is dedicated to
a user, it is unavailable (usually because of a hardware condition).
If a graphic display device has a user logged on or dialed through it, you see
something like this:
