A.4 Component Status
The ftsmaint ls command lists the components in the system and identifies any components that have been removed
from service. The list serves as a simple troubleshooting tool to verify that all the components are present and shows
their status (in/out of service). Refer to PA-8500 Continuum Series 400 Technical Service Guide (HP-
UX systems),
Section 2.6.3 to view a sample ftsmaint ls output screen.
A.4.1 Software State Information
The system creates a node for each hardware device that is either installed or listed in the /stand/ioconfig file.
The State field in the
ftsmaint ls display can show a hardware component to be in any one of the software states
shown in the following table.
State
Meaning
UNCLAIMED Initialization state, or hardware exists, and no software is associated with the node.
CLAIMED The driver recognizes the device.
ERROR The device is recognized, but it is in an error state.
NO_HW The device at this hardware path is no longer responding.
SCAN
Transitional state that indicates the device is locked. A device is temporarily put in the SCAN state
when it is being scanned by the
ioscan or ftsmaint utilities.
The software state of a hardware component can change. For example, a component is initially created in the
UNCLAIMED
state when it is detected at boot time. The component moves to the
CLAIMED state when it is recognized and claimed by
the appropriate driver. The transitions between the various software states are controlled by the
ioscan and ftsmaint
utilities.
A.4.2 Hardware Status Information
In addition to a software state, each hardware component has a particular hardware status. The Status field in the
ftsmaint ls display can have any of the values shown in the following table.
Status Meaning
Online The device is actively working.
Online
Standby
The device is not logically active, but it is operational. Using the ftsmaint switch or
ftsmaint sync command can be used to change the device status to Online.
Duplexed The status is appended to the Online status to indicate that the device is fully duplexed.
The status is appended to the Online or Online Standby status to indicate that the
