How to verify that fiber card is bad

I have a fiber card that is down. This is a HP Tachyon XL2 Fibre Channel card on a HP 9000, RP3440 server running HP-UX 11.11.

There is a single light lit on the card and that light stay's lit whether the fiber is plugged in or not.

I ran fcmsutil /dev/td1 and it shows that the topology and Link Speed are "UNINITIALIZED". Also the driver state is "AWAITING_LINK_UP". We moved the fiber on the switch and it still shows down, so we know that it issue is not on the switch.

Is there a way to Initialize the card? Or does it get initialize when the fiber is plugged in?

Any additional advice would be appreciated.

Thanks.

Re: How to verify that fiber card is bad

Which card do you have?

The driver "initializes" the card as long as the driver has claimed it. Check with ioscan. You can reset and test it using fcmsutil:

From the man page:
fcmsutil(1M) fcmsutil(1M)

reset This option is used to reset the HBA (or a single FC
port in case of DUAL PORT and FC/GigE Combo cards).
WARNING: This is a DESTRUCTIVE test. The reset
operation will result in aborting communication to all
nodes till the process is completed. This option only
results in a soft reset for the TACHYON TL and TACHYON
XL2 cards and does not result in termination of
communication.

[-f] bdr (TL/XL/QL)
The bdr option is used to issue a Bus Device Reset to
device. WARNING: This is a DESTRUCTIVE test. The -f
option can be used to suppress the warning message
displayed by TACHYON TL, TACHYON XL2, DUAL PORT and
FC/GigE Combo cards.

This option resets the target, clearing all commands,
without doing any checks. This option is supported
only by TACHYON TL, TACHYON XL2, DUAL PORT and FC/GigE
COMBO cards.

You should get a link led as soon as the cable is connected.

See the fcmsutil stat option to review the link counters.

Re: How to verify that fiber card is bad

Trying a different port on the switch was a good idea.

Have you tried a different FC cable? If not, I would try that.

I you still don't get a link then you may want to try the commands posted above.
