lssf(1M) lssf(1M)

NAME

lssf - list a special ﬁle

SYNOPSIS

/sbin/lssf special_ﬁle ...

DESCRIPTION

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 spe-

cial 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)).

DIAGNOSTICS

Most diagnostic messages from

lssf are self explanatory. Listed below are some messages deserving

further clariﬁcation. Warnings allow

lssf to continue.

Warnings

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 /etc/ioconfig

<special_file> is not a special file

The ﬁle is not associated with an I/O device.

EXAMPLES

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 produces:

tape2 instance 2 bpi 1600 att address 8.6.1 rmt/c2t6d0m
