Tachyon FC not running on HPUX 11.11

[Neeraj Bajpai]

Hi Admin,

before putting this query I have checked in forum and could not able to solve my problem related to A6795A Tachyon FC PCI card.

I have installed this card in rp2470 A class machine on HPUX 11.11 which is connected to IBM storage via brocaded switch and one LUN assigned to this machine.

Some details about the card...

1. Card is claimed
fc 0 0/2/0/0 td CLAIMED INTERFACE HP Tachyon XL2 Fibre Channel Mass Storage Adapter
/dev/td0

2. uname output
B.11.11 U 9000/800 871930671

3. Patches installed
# FC-TACHYON-TL
# FC-TACHYON-TL.FC-TL-KRN Configured
PHSS_26799.FC-TL-KRN configured
# FC-TACHYON-TL.FC-TL-RUN configured
PHSS_26799.FC-TL-RUN configured
# FCMassStorage
# FCMassStorage.FCMS-ENG-A-MAN configured
PHKL_28984.FCMS-ENG-A-MAN configured
# FCMassStorage.FCMS-INIT configured
# FCMassStorage.FCMS-JPN-E-MAN configured
# FCMassStorage.FCMS-JPN-S-MAN configured
# FCMassStorage.FCMS-KRN configured
PHKL_28984.FCMS-KRN configured
# FCMassStorage.FCMS-RUN configured
PHKL_28984.FCMS-RUN configured

4. # swlist -l patch -a state | grep PHKL_23626

I couldnt see any output, and when I am trying to install the same patch it says it is already loded.



As per my understanding I have installed all the patches and patches for Fiber Channel Masss storage too, but when kernel is loaded it gives the follwoing error

Nov 19 14:59:11 apchsrv vmunix: td: claimed Tachyon XL2 Fibre Channel Mass Storage card at 0/2/0/0
Nov 19 14:59:11 apchsrv vmunix: ct_query failed. hw_path = 0/2/0/0

can any one having any idea about this problem...

thanks in advance

Hi,

Try this link from itrc,

The itrc doc id is UMASSKBRC00011649.

Hope this helps.

Hi Neeraj,

PHKL_23626 has been superseded by the patch PHKL_28984 which you already have. However, looks like PHKL_28984 has warnings on it and HP recommends to install PHKL_27751 instead of PHKL_27751.

Are you not able to see the disks at the path 0/2/0/0. Can you post the output of 'tdutil /dev/tdx' corresponding to this path?.

You may have a corrupted or partially installed patch.

I recommend swverify \*

Do this prior to installing the patch that Sri recommends.

If any of the patches relating to the Tachyon card are corrupt. If so, swremove them and reinstall them.

I've had other hardware that was claimed but still quite dead. Fire up cstm mstm or the X Windows based xstm and test the hardware. If you get a failure the thing needs to be replaced.

Good Luck,

ct_query failed. hw_path = some/hw/path appears
usually if the fabric/loop is available/connected but no disk is assigned.

Just configure your zoning and the "error"
should be gone.

Neeraj,

the "ct_query failed" is typical for an FC card with nothing attached or no link.

you can check current status with
fcmsutil /dev/td0

this should show that the driver is available and the card is fabric attached.

if not the common error would be that the receive and transmit fibres are reversed.

In that case try to change the two connetions either at the switch or the HBA.

Also (if you can) log in to the brocade and do a switchshow, with a valid fabric login of the HBA you should see the HBA WWN which you also get from the fcmsutil command.

Regards,
Bernhard

Did you try running fcmsutil /dev/td0 stat to see if the system even sees the card?

Hi All

Thanks for your reply, every one is almost right, identified the problem. but I was stress by time so I reinstall the card again and it works fine.

I saw the LUN correctly.

once again thanks for your valuable input and time.
