Fibre Channel Device and Adapter Support on HP e 3000 Systems

TDUTIL — Fibre Channel Diagnostic Utility

TDUTIL is a new utility introduced in MPE/iX 7.5 for obtaining information on fibre channel host bus

adapters, supported on HP e3000 systems. This utility provides the ability to display information such as the

N_Port ID, Node World-Wide Name, Port World-Wide Name, link speed, chip revision number, VPD (Vital

Product Data) information and more.

The utility can be run from MPE/iX CI command prompt by giving the FC adapter hardware path as

parameter.

:tdutil <adapter hardware path>

TDUTIL Sample Output

A sample output of TDUTIL utility is shown below:

:tdutil 0/8/0/0

Vendor ID is = 0x00103c

Device ID is = 0x001029

XL2 Chip Revision No is = 2.2

PCI Sub-system Vendor ID is = 0x00103c

PCI Sub-system ID is = 0x00128c

Topology = PTTOPT_FABRIC

Link Speed = 1Gb

Local N_Port_id is = 0x011c00

N_Port Node World Wide Name = 0x50060b00001000d4

N_Port Port World Wide Name = 0x50060b00001000d3

Driver state = ONLINE

Hardware Path is = 0/8/0/0

Number of Assisted IOs = 126053

Number of Active Login Sessions = 1

Maximum Frame Size = 960

Driver Version = @(#) HP Fibre Channel Tachyon TL/TS/XL2 Driver B.11.00.10 (AR1201) Nov

17 2001

Invoking TDUTIL without specifying any options displays the adapter related information like the topology,

link state, link speed, vendor ID, NPort ID, Port and Node WWNs, number of I/Os done so far, etc.

The most important things to note here are the Topology and the Driver state. The topology can be any of the

following:

• PRIVATE_LOOP, when the card is in private loop topology.

• PUBLIC_LOOP, when the card is in public loop topology, i.e., a loop containing a switch.

• PTTOPT_FABRIC, when the card is directly attached to a switch.

• UNINITIALIZED, when the link has not been initialized, either due to the card not being connected to a

cable or the device/switch connected on the cable is not functional.
