lssf - list a special file
/sbin/lssf special_file ...
lssf lists information about a special file. For each special_file
name, lssf determines the major number of the special file and whether
it is block or character (using stat(2)). It then scans the system
for the device that is associated with the special file. When the
device is found, the minor number of the special file is decoded. A
mnemonic description of the minor number is printed on standard output
along with the hardware path (i.e., address) of the device. Mnemonics
used to describe the fields are closely related to the options used
with mksf (see mksf(1M)).
Most diagnostic messages from lssf are self explanatory. Listed below
are some messages deserving further clarification. Warnings allow
lssf to continue.
No such device in the system
There is no information about the device in the kernel. The
special file is not usable. Use rmsf to remove the special
file (see rmsf(1M)).
Character major <<<<major>>>> is not in the kernel
Block major <<<<major>>>> is not in the kernel
The major number associated with the special file is not in
the kernel. Use config to add the appropriate driver to the
kernel (see config(1M)).
Device driver <<<<name>>>> is not in the kernel
Device class <<<<name>>>> is not in the kernel
The indicated device driver or device class is not present
in the kernel. An open() of a special file pointing to an
unusable device fails. To make the device usable, the
appropriate device driver and/or device class must be added
to the config input file and a new kernel generated (see
config(1M)). If the device is no longer needed, rmsf should
be used to remove the special files and update
<<<<special_file>>>> is not a special file
The file is not associated with an I/O device.
Suppose a special file is created with the command mksf -d tape2 -H
8.6.1 -b 1600 -a rmt/c2t6d0m. The command lssf rmt/c2t6d0m then
