ioscan

[Shaamil]

Hi gurus,
This might soundlike a dumb question, but can anyone tell me what the fc Class is for, this is under ioscan.

The reason I am asking is that I have two fiber cards in the server, but my ioscan does not pick it up. I do get two unclaimed devices
and the Class is fc, but the driver is td....what this is, I do not know.
The decription I get for these devices under ioscan is PCI buss adapter.
Please lk at attached note.

Hi,

have you checked the presence of td and fcp drivers in the kernel?

# sam ---> kernel configuration ---> drivers

Are they there with status "In"?

Best regards,
Ettore

What do you get if you do:
ioscan -funC lan

You should see your adapters with ioscan -fnC fc. They will show up with the driver being 'td'.

The following example is from one of our test boxes where we have A5158 (td) and A3740 (fcms) cards:

ioscan -fnCfc
Class I H/W Path Driver S/W State H/W Type Description
=================================================================
fc 4 0/0/0 td CLAIMED INTERFACE HP Tachyon TL/TS Fibre Channel Mass Storage Adapter
/dev/td4
fc 5 3/0/0 td CLAIMED INTERFACE HP Tachyon TL/TS Fibre Channel Mass Storage Adapter
/dev/td5
fc 2 4/1/0 fcT1 CLAIMED INTERFACE HP Fibre Channel Mass Storage Adapter
/dev/fcms3
fc 3 5/2/0 fcT1 CLAIMED INTERFACE HP Fibre Channel Mass Storage Adapter
fc 0 6/2/0 fcT1 CLAIMED
/dev/fcms7

If the device files have been created (e.g. /dev/td[0-9]) then you may need to load the appropriate driver.

Can you provide OS, HBA model, and also how its being connected to storage (e.g. direct connect, fabric).

As you probably know this are your fiber channel card.

You have to install the appropriate drivers for them. The bundle is called FibrChanl-00 and is on the Core OS CD/DVD

After installation is complete the kernel is compiled, system boots and special files like /dev/td* are created.

You can use then ioscan -fnC fc to see the coresponding special file, and then use fcmsutil /dev/tdX (wher X is as shown in ioscan output) to see details about the card.

And one more thing... After I saw your output I bet you have two
(A5158A) HP Tachyon TL/TS Fibre Channel Mass Storage Adapter
which are running at 1Gb/s max.

The actual filesets you after will be similar to the following. This has happened because the cards were installed after the OS installation.
The FCMassStorage filesets and FC will be on the core OS CD. You may still need to get an up to date driver for FC from here:

FC class is for fibre channel cards.

Get the device name and run "tdutil" to get further details and diagnostic information of the card.

Pl check the manpage of tdutil for syntax
#tdutil /dev/td0.
