HP-UX System Administrator's Guide: Overview

insf could be run to create device special files for that new
hardware without having to wait for a reboot of the system)

.
See insf(1M) for details.
With the -L option, insf enables the legacy naming model.
mksf
Used to create a single device special file, usually with
non-default characteristics. For details on specifying the
parameters for your device special file, see mksf(1M).
If you wish to create a single device special file, perhaps with
specific parameters, use mksf instead of insf. For details on
specifying the parameters for your device special file, see
mksf(1M).
lssf lssf lists information about specified device special files (in
a friendly, human readable form). For example, lssf can list
stale device special files. You can specify legacy or persistent
device special files. For details and examples of lssf output,
see lssf(1M).
rmsf rmsf removes specified device special files. For information
about the many rmsf options for specifying which device
special files to remove (and from where to remove them), see
the rmsf(1M) manpage.
With the -L option, rmsf disables the legacy naming model,
removing all legacy I/O nodes and their device special files
from the system.
io_redirect_dsf io_redirect_dsf reassigns an existing device special file
from one device to another. Because this takes advantage of
one of the primary benefits of persistent device special files,
it will not work with legacy device special files. See
io_redirect_dsf(1M) for details.
ioscan ioscan performs many functions. Primarily it scans a server’s
hardware, binding new hardware with appropriate drivers.
With regard to device special files, ioscan can display the
mapping between legacy device special files and persistent
device special files. See ioscan(1M) for details on ioscan’s
many functions and options.
scsimgr scsimgr, like ioscan, has many functions other than working
with device special files. But, you can use scsimgr to validate
the change of a LUN associated with a legacy device special
file (replace a legacy device special file). If you have replaced
3. In some cases, new hardware is automatically discovered and associated persistent device special files
are created, even before ioscan is run. However, if you have new hardware with no associated device
special files, insf can create them for you.
