• ioscan -m hwpath displays the mapping between (legacy) hardware path, lunpath hardware
path, and LUN hardware path.
•
ioscan -m cluster_dsf displays the mapping between cluster device special files, legacy device
special files, and persistent device special files.
•
ioscan -m resourcepath displays the mapping between hardware path, physical location and
resourcepath. The resource path format applies to the platforms where Onboard Administrator (OA)
based partition management is supported. (For more information on resourcepath see resour-
cepath (5)).
•
ioscan -s lists the stale entries present in the system.
•
ioscan -r reverts the deferred binding action on a device lunpath.
•
ioscan -B lists all the pending deferred bindings.
•
ioscan -U scans all unclaimed nodes of type INTERFACE.
•
ioscan -a shows information about thread 0 for a processor with Hyper Threading feature.
•
ioscan -A displays the alias path of a node.
Security Restriction
Generally,
ioscan requires superuser privileges. A non root user may use the following options:
-k only to display the kernel hardware tree.
-m use the mapping features.
-P display the property of a node.
-B list pending deferred bindings.
-t display date and time of the last system hardware scan.
-u list usable I/O system devices.
-a display information about thread 0 of a processor with Hyper Threading feature.
Driver binding and actual hardware scanning is restricted to root.
Options
ioscan recognizes the following options:
-A Display the alias_path of a node. The alias_path is an alternative user-friendly
name assigned to a hardware path. Must be used with the -F option.
-a Show information about thread "0" for a processor with Hyper Threading feature.
When used with the -F option, the ioscan command generates a compact listing
of fields separated by colons (:), which is useful for producing custom listings with
awk. Fields include: socket , core , thread .
-b Defer the binding of a driver to a hardware path until the next system boot. Must
be used with the -M and -H options.
-B List all the pending deferred bindings.
-C class Restrict the output listing to those devices belonging to the specified class . Cannot
be used with -d.
-d driver Restrict the output listing to those devices controlled by the specified driver . Can-
not be used with -C.
-e Display the device path as follows:
On Integrity servers, display the EFI (Extensible Firmware Interface) device paths
when available.
On PA-RISC Hardware, when used with the
-N option, display the PA device path
when available in hexadecimal and also display the PA device path in decimal for-
mat separated with a comma ,. This form is to be used when booting from ISL in
the hpux command prompt with the -a option (see hpux(1M)). The same format
can be used to enter a lunpath hardware path at the Boot Console Handler (BCH)
boot prompt.
