NO_HW the hardware at this address is no longer responding
ERROR the hardware at this address is responding but is in an error state
SCAN a scan operation is in progress for this node
hardware type Entity identifier for the hardware component. The entity identifier is one of the follow-
ing strings:
UNKNOWN there is no hardware associated or the type of hardware is unknown
PROCESSOR hardware component is a processor
MEMORY hardware component is memory
BUS_NEXUS hardware component is bus converter or bus adapter
VIRTBUS hardware component is a virtual (software controlled) bus
INTERFACE hardware component is an interface card
DEVICE hardware component is a device
TGT_PATH hardware component is a target path
LUN_PATH hardware component is a LUN path
description A description of the device.
card instance The instance number of the hardware interface card.
is_remote Displays
T if the device is connected remotely or F if the device is connected locally.
Displaying is_remote is deprecated in HP-UX 11i v3.
EFI device path or PA device path
On Integrity servers hardware, this field contains the EFI device path. On PA-RISC
hardware, this field contains the PA device path in both hexadecimal and decimal for-
mat separated by a comma
,.
health State of the node as defined by the subsystem that manages this node (for example, a
driver). The health is one of the following strings:
online node is online and functional
offline node has gone offline and is inaccessible
limited node is online but performance is degraded due to some links, paths,
and connections being offline
unusable an error condition occurred which requires manual intervention (for
example, authentication failure, hardware failure, and so on)
testing node is being diagnosed
disabled node has been disabled or suspended
standby node is functional but not in use (standby node)
N/A Property Not Available
alias_path An alternative user-friendly name assigned to a hardware path.
RETURN VALUE
ioscan returns:
0 upon normal completion
1 if an error occurred
2 if the driver does not support the functionality.
EXAMPLES
