QUERY (Real Device)
q 280-285
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
Ready;
The first number listed 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 and the
rest are volume labels of the devices. The last number 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.
q 181a-181c
DASD 181A CP SYSTEM ESAP2C SHARED
DASD 181B CP OWNED ESAP2F RESERVE PENDING FOR USER DAVID
DASD 181C CP OWNED ESAP30 RESERVED BY SYSTEM
Ready;
If a DASD at the specified address is dedicated to a user, you will see a message
like this:
q 820
DASD 0820 ATTACHED TO OLIVER 01FC R/0 XAUSR4
Ready;
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 that the user OLIVER has read-only access to the DASD.
R/O might also read R/W, which would mean that the user had 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).
If the device was defined by the DEVNO option on the MDISK statement, you see a
response like this:
QUERY F8A3
DASD F8A3 CP SYSTEM DEVNO 13
958 z/VM: CP Commands and Utilities Reference
The first number listed is the real device number of the DASD. SYSTEM indicates
the device is allocated for use as a minidisk. DEVNO indicates that this device was
defined by the DEVNO option on the MDISK statement. The last number indicates
the number of links to the full-pack minidisk.
There must be at least one link, either by the owner of the disk or another user, to
get the DEVNO response. One cannot link to a DEVNO mdisk attached to the
system, it must be a free device. Even when linked, a DEVNO device is not
attached to the system.
The volser for a DEVNO device is available from QUERY SYSTEM rdev.
