MOUNT
(LD)
Associates the logical-disk unit (LDn) you specify with the file you specify. This
enables you to use a logical disk as if it were a physical disk.
Format
MOUNT logical-disk-unit filespec [logical-device-name]
Command Options
/READONLY
/[NO]WRITE
Parameters
logical-disk-unit
Specifies the the logical-disk unit you want to mount; for example, LD7 specifies
logical-disk unit 7. If you do not specify a number for a logical-disk unit, the
number defaults to 0.
The MOUNT command associates a logical-disk file with one of eight logical-disk
units (LD0–LD7). If you perform a system generation (SYSGEN), and request
extended device-unit support, you can access up to 32 logical-disk units at one
time.
filespec
Specifies the device and file being mounted. The default file type for a file
mounted as a logical disk is DSK.
logical-device-name
Specifies an optional logical name assigned to the logical disk. The logical device
name can be one to three characters long, followed by an optional colon (:). All
alphanumeric characters are valid, but the first character must be a letter.
Description
See the Introduction to RT–11 for a tutorial explanation of how to use the Logical Disk
(LD) runnable handler, and see the RT–11 System Utilities Manual for a description
of that handler.
The file you associate with a logical-disk unit is protected from deletion after you
associate it with a unit. The handler for the device containing the file must be
loaded. If the handler is not loaded, the MOUNT command loads that handler.
