number replacement. Online instance number replacement means that the
instance number of a node can be modified without a system reboot. The
is_inst_replaceable property can be set to one of the following values:
True The driver corresponding to this node supports online instance
number replacement.
False The driver corresponding to this node does not support online
instance number replacement.
N/A The is_inst_replaceable property is not available for the driver
corresponding to this node.
wwid
This property indicates the
LUN WorldWide Identifier (WWID)
.
uniq_name
This property indicates the
HP-UX specific LUN unique identif-
ier.
For more information on the wwid and uniq_name properties, refer to the
scsimgr(1M) manpage.
alias_path
This property indicates the alias path of a node. Alias path is an alternative
user-friendly name assigned to a hardware path.
physical_location
This property indicates the Physical location. This hexadecimal value
indicates the actual physical device location. A physical location consistently
refers to a device based on where the device is physically located in the system
configuration.
ms_scan_time
This property shows the time taken by the IO subsystem to scan a device.
This value is updated every time a system hardware is actually scanned. The
time listed will be in the following format: MM min SS sec UUU ms. The
scan time will be displayed only for the mass storage devices, for non mass
storage devices it will be displayed as
N/A.
NOTE: For a bus node, the ms_scan_time is the total time taken to scan the
bus node and all the devices connected to it.
-r Remove a deferred binding at the specified hardware path. Must be used with the
-H option. The hw_path must belong to the agile view.
-s List stale I/O node entries that are present in the system. These entries correspond
to nodes that have an entry in the system I/O configuration file, but the correspond-
ing device is not found (see ioconfig(4)).
-t Display the date and time at which the system hardware was last scanned. For
example, ioscan -t displays the following output:
Fri Nov 22 11:22:21 2005.
-u Scan and list usable I/O system devices instead of the actual hardware. Usable I/O
devices are those having a driver in the kernel and an assigned instance number.
The -d, -C, -I, and -H options can be used to restrict listings. The -u option can-
not be used with -k.
-U Initiate a scan on unclaimed nodes of type INTERFACE in the agile view.
The
-d and -C options can be used to obtain listings of subsets of the I/O system, although the entire sys-
tem is still scanned. Specifying -H option causes ioscan to restrict both the scan and the listing to the
hardware subset indicated.
Fields
The
-F option can be used to generate a compact listing of fields separated by colons (:), useful for pro-
ducing custom listings with awk.
