–m hwpath [-H hardware_path]
Displays the mappings between a LUN legacy, lunpath, and LUN hardware paths. Any type of
hardware path can be specified. If no hardware path is specified, the mapping is displayed for all
entries. For example:
# ioscan -m hwpath -H 0/4/1/1.124.2.0.0.0.1
Lun H/W Path Lunpath H/W Path Legacy H/W Path

–m lun [–H LUN_hardware_path] [dsf_name]
Displays the mappings between a LUN hardware path and its lunpath hardware paths. Use the –d,
-C, -I or –H options or a device file name to limit the ioscan output to particular entries. For
example:
# ioscan -m lun /dev/disk/disk50

–s Displays stale entries–those devices that have no associated hardware.
–U Initiates a hardware scan on all entries that have no associated driver. It probes only nodes that are
in the UNCLAIMED state.
–e Displays the Extensible Firmware Interface (EFI) format on HP Integrity systems and Boot Console
Handler (BCH) format on PA-RISC systems. For more information on BCH format, see the impacts
section on PA-RISC Boot Subsystem
.
–b, -r, -B
Initiates, removes, and lists deferred bindings. The existing –M and –H options force a named driver
to bind to a specified hardware path. If that driver does not support online binding or the currently
bound driver cannot unbind, then the binding operation is deferred until the next reboot. The –b
option explicitly requests a deferred binding rather than an immediate one. The -r option, when used
with the -H option, removes a deferred binding. The -B option lists all deferred bindings. For
examples, see Force-Binding a Driver
.
insf(1M)
The insf command assigns instance numbers to devices and installs DSFs. When run without options, insf
creates both legacy and persistent DSFs for all new devices. The insf command supports one new option:
