Fields include the module’s: bus type , cdio, is_block , is_char , is_pseudo , block major number, character
major number , minor number, class , driver , hardware path, identify bytes , instance number, module
path , module name, software state , hardware type , a brief description , card instance , is_remote , EFI
device path or PA device path , health , and alias_path .
The additional field is_remote is displayed only when the
-F option is specified twice (-FF or -F -F).
The field EFI device path or PA device path is displayed on Integrity systems or PA-RISC systems
respectively only when the
-e option is specified with the
-F option.
If the
-N option is specified with the
-F option, the health property is added at the end of the listing.
If the
-A option is specified with the
-F option, the alias_path field is displayed at the end of the listing.
If a field does not exist, consecutive colons hold the field’s position.
Note: The number of fields in the
ioscan -F output can be extended by adding additional colon
separated fields at the end of the listing. Fields are defined as follows:
bus type Bus type associated with the node.
cdio The name associated with the Context-Dependent I/O module.
is_block A boolean value indicating whether a device block major number exists. A T or F is
generated in this field.
is_char A boolean value indicating whether a device character major number exists. A
T or F
is generated in this field.
is_pseudo A boolean value indicating a pseudo driver. A
T or F is generated in this field.
block major The device block major number. A
-1 indicates that a device block major number does
not exist.
character major The device character major number. A
-1 indicates that a device character major
number does not exist.
minor The device minor number.
class A device category, defined in the files located in the directory
/usr/conf/master.d
and consistent with the listings output by lsdev (see lsdev (1M)). Examples are disk,
printer, and tape.
driver The name of the driver that controls the hardware component. If no driver is available
to control the hardware component, a question mark (
?) is displayed in the output.
hw path A numerical string of hardware components, notated sequentially from the bus address
to the device address. Typically, the initial number is appended by slash (
/), to
represent a bus converter (if required by your machine), and subsequent numbers are
separated by periods (
.). Each number represents the location of a hardware com-
ponent on the path to the device.
identify bytes The identify bytes returned from a module or device.
instance The instance number associated with the device or card. The instance number is a
unique number assigned to a card or device within a class. If no driver is available for
the hardware component or an error occurs binding the driver, the kernel will not
assign an instance number and a (
-1), is listed.
module path The software components separated by periods (
.).
module name The module name of the software component controlling the node.
software state The result of software binding.
CLAIMED software bound successfully
UNCLAIMED no associated software found
UNUSABLE the hardware at this address is no longer usable due to some irrecover-
able error condition; a system reboot may clear this condition
SUSPENDED associated software and hardware are in suspended state
DIFF_HW the hardware at this address does not match the previously associated
hardware
