MOUNT
Even if you reboot the computer, an association (but not the logical name assignment)
made with the MOUNT command is maintained until you change it. However,
the MOUNT information is contained within the image of the LD handler. So, if
you explicitly unload the device handler referenced in the filespec in the MOUNT
command, or if you reboot your processor, the access to the association is lost until
you reload the handler. For example, this can happen if you switch between a
mapped and an unmapped monitor.
Verifying Logical-Disk Assignments
Issue the SHOW SUBSET command to verify your logical-disk assignments:
.SHOW SUBSET
Freeing Nested Logical-Disk Units
If you dismount a primary logical-disk file and its unit without first dismounting
nested logical-disk units, issue the SET LD CLEAN command to free the nested
logical-disk units. See the SET command description for more information on SET
LD CLEAN.
The DISMOUNT Command Disassociates a Logical-Disk Association
Use the DISMOUNT command to disassociate a logical disk from a logical-disk unit.
Options
/READONLY
Does not allow WRITE access through LD to any files contained in the specified
logical-disk unit.
/[NO]WRITE
/WRITE makes the logical disk write enabled. This is the default.
/NOWRITE makes the logical disk write protected. This option allows you read-
only access to the logical disk you specify.
Examples
1. This command example associates logical-disk unit 5 (LD5) with the file
DATA.DSK on device DU1:
.MOUNT LD5: DU1:DATA
2. This command example associates LD5 with the file DU1:DATA.DSK, after LD5
has been assigned the logical-device name OUT. When the command is executed,
the logical-device name TST is also assigned to LD5:
.ASSIGN LD5: OUT
.MOUNT
Device? OUT
File? DL0:DATA TST
