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

CLAIMED

ERROR

NO_HW

SCAN

Initialization state, or hardware exists, and no software is associated with the node.

The driver recognizes the device.

The device is recognized, but it is in an error state.

The device at this hardware path is no longer responding.

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
