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.

A sample output of TDUTIL utility is shown below:
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.
The Driver State represents the state of the software driver
controlling the adapter card. When the driver and the card are functioning
properly, the Driver state should be ONLINE. Any other state can
be considered a transient one with the exceptions of the states
AWAITING_LINK_UP and OFFLINE. It is normal for the driver to temporarily
stay in AWAITING_LINK_UP state, but if it stays for too long, typically
more than 5 seconds, then there is a problem in the cable or with
the device at the other end. If a loop contains multiple devices
along with the host adapter card, one of the devices going faulty
can temporarily result in the driver going out of ONLINE state.
If the loop is through an FC hub, then the hub will automatically
bypass the faulty device and the driver will come back to ONLINE
state immediately.
Due to the impact on the functioning of the driver by using
TDUTIL, only a user logging in as MANAGER.SYS can invoke the utility.

 | NOTE: TDUTIL supports usage of options while invoking the
utility but these options are meant to be used only by HP Support
Representatives for troubleshooting. Customers are advised to use TDUTIL
only by specifying the adapter path and not make use of use any
of the options. |
