DEASSIGN
(KMON)
Disassociates a logical device name from a physical device name.
Format
DEASSIGN [logical-device-name]
Parameter
logical-device-name
Specifies an alphanumeric name, from one to three characters long and followed
by an optional colon, that is assigned to a particular device. Note that spaces
and tabs are not permitted in the logical device name.
Examples
1. To remove the assignment of a particular logical device name to a particular
device, specify that logical device name in the command line. The following
example disassociates the logical name INP from the physical device to which it
is assigned:
.DEASSIGN INP:
2. If you specify a logical name that is not currently assigned, RT–11 displays an
error message, as this example shows:
.DEASSIGN INP:
?KMON-W-Logical name not found INP:
3. To return your system to having no default device for undefined devices or logical
device names, use the following command:
.DEASSIGN *
See the ASSIGN command description for an explanation of how and when to
assign a default device.
4. To disassociate all logical names from physical devices, type the DEASSIGN
command without an argument. The following example disassociates all logical
device names (except SY) from physical devices and resets the logical names DK
and SY to represent the system volume:
.DEASSIGN
5. If DK is assigned to a nonsystem device, the following command disassociates DK
from DU1 and restores the default association of DK to SY, the system device:
.DEASSIGN DK:
