QUERY MDISK
Responses
2. For more information on the duplex control operations that CP provides when
you specify DETAILS, see “DUPLEX” on page 413.
3. The OwnerID and Odev listed in the output can be different, depending on how
the disk was defined. If the disk definition in the system directory has been
changed, the new OwnerID and Odev may not be immediately reflected in the
QUERY MDISK output. The old designation will be shown until there are no
users accessing the disk. Use the form of the command consistent with the
output needed for your application.
Response 1:
If you do not specify DETAILS or LOCATION, you see this type of response:
query mdisk 190
TargetID Tdev OwnerID Odev
RICH 0190 MAINT 0190
Ready;
This example tells you that RICH’s 190 disk is really MAINT’s 190 disk (MAINT is
the owner of the disk).

If you specify DETAILS, CP adds more information to the response:
query mdisk 190 details
TargetID Tdev OwnerID Odev Minidisk DEVNO Duplex
RICH 0190 MAINT 0190 Regular No No
Ready;
This example tells you MAINT’s 190 disk is a regular minidisk, it does not have the
DEVNO operand of the MDISK statement defined in the user’s directory entry, and
no duplex control operations are in effect for this disk.
The possible values for the Minidisk column are:
Dedicated
The real device associated with the specified virtual device is dedicated.
Full pack
The specified virtual device is a full-pack minidisk.
Regular
The specified virtual device is a non-full-pack minidisk. Note: This category
includes T-disks and virtual disks in storage.
The possible values for the DEVNO column are:
No The minidisk is not defined using the DEVNO operand of the MDISK
statement in the user’s directory entry.
Yes The minidisk is defined using the DEVNO operand of the MDISK statement
in the user’s directory entry.
The possible values for the Duplex column are:
No The minidisk has no duplex control operations in effect.
