Status of qlogic tcp/ip (fc0) support

Status of qlogic tcp/ip (fc0) support

[Mario Giammarco]

Hello,
I now have a qlogic 2200 card and I am trying tcp/ip support:

- standard qlogicfc built in kernel seems to not support ip (I heard
there is a patch somewhere, is it right?)

- qla drivers 6.00 of qlogic website should support it but I am not able
to compile them with IP=1 option (I have tried on kernels 2.4.22 2.4.23)

- qla drivers 8.00 on sourceforge seems to not support it (and they
works only on 2.6.0 kernel).

Now I am stuck please help me I need them badly.

Thanks in advance for any help.

Hello, using qla2200 from qlogic is IMHO the good solution.
I've already tested it a few months ago and it worked fine except very 
poor performance (around 20MB/s with a Qlogic switch despite of no load 
at all).

You should send your compile errors...

Poor tcp/ip performance or scsi performance?

Yeah!

Here is the complete log:

Hello, I've CC the email to the list, other people could be interested...

Well, it wasn't very difficult.
After building qla2?00.o with IP option and building qlaip, you just 
have to load these 2 modules.
Then, you can see a new network interface (see ifconfig -a).
You can use it like any ethernet devices...

You may also encounter difficulties related to FC connection between 
your servers. In my test, I was using Qlogic Sanbox2 switch with 
broadcasting activated.

Re: Status of qlogic tcp/ip (fc0) support

[r35157anc3]

Thanks very much. I've made it as far as setting up the network devices. 
I now have fc0 network device and with an internal ip, but I can't 
figure out how I am supposed to mount it? I can mount it over scsi?  
What if I am trying to access the fc remotely? I guess I just don't 
understand, but beyond setting up the qla2xip kernel drivers, the 
documentation doesn't say much.

Re: Status of qlogic tcp/ip (fc0) support

You can communicate with other servers on the same SAN network also 
using FC-IP.
I don't understand what you mean with "mount" ?
You have nothing to mount, it's a network interface like any other one 
to use classic IP protocol.

It has nothing to do with iSCSI or something like that...

Re: Status of qlogic tcp/ip (fc0) support

[r35157anc3]

I've isolated myself from the SAN network and I'm operating in my own 
private subnet. It's just my server, the FC controller, and a hard drive 
connected to the controller.

I want to connect to devices interfaced with the FC over IP. I have a 
hard drive interfaced with a qla 2300 controller. Now that I have the FC 
setup for IP, how would I mount that disk?

Perhaps I'm going about this all wrong though. I always thought IP was 
an alternative to SCSI for FC. Usually, I mount my SCSI devices. If I'm 
not going to use SCSI, then how do I use it if not by mounting?

Thanks for being so helpful,

Yes !
You can't mount devices using IP over FC.
You can only access other FC nodes (essentially servers) that also have 
IP over FC activated.
It could be useful for example to share storage over NFS in a cluster 
connected to the same SAN, because there are not many Shared FileSystem 
(except GFS but it's no longer GPL...).

No, you won't be able to mount your SCSI devices.
If you want to this, use SCSI over FC, it's the traditionnal way to do it.
You *really* have no interest, even it would be possible, to use IP to 
mount SCSI devices...

Exactly ! It's the same as you would have if you connect your servers

I recently read an article on iSCSI and FCIP. That's what initially got 
me interested in this. I think this is actually what I'm wanting to do 
here. Do you know if the qla 2300 HBA is capable of iSCSI? Is there a 
linux driver for iSCSI or any plans for one?

No, the 2xxx series HBAs are *not* iSCSI HBAs.  QLogic does make iSCSI
HBAs (the 4xxx series cards), info at qlogic.com.

For the 4xxx series HBAs, yes.

I am getting crazy.

I have tried with 2.4.18 2.4.22 2.4.23 2.6.0-test11 and I was not able to compile it.

What am I doing wrong?

Thank you very much! It almost works now!
BTW: I checked again qlogic website and I have not found it...
BTW2: About iSCSI. There are several software iscsi initiator and target
for linux (search with google and in sourceforge). I suggest ardis
target and cisco initiator. They are completely software so they run on
every tcp/ip based network. I have tested them on ethernet but they
should run also on fc0. But they are completely software based: they use
fibre channel only like a fast ethernet.

AND NOW the big problem:

I try to ping from qlogic card to mpt-fusion (lsi logic) card and
viceversa.

Hardware works (both cards see my fibre channel hard disks)

All packets are lost (destination host unreachable), route is ok.

On qlogic based host I see in dmesg output:

qla2x00_send_packet: Unable to determine loop id for destination.
qla2200ip: fc0 - Unable to send packet -- Bad error occured!!!
qla2x00_send_packet: Unable to determine loop id for destination.
qla2200ip: fc0 - Unable to send packet -- Bad error occured!!!
qla2x00_send_packet: Unable to determine loop id for destination.
qla2200ip: fc0 - Unable to send packet -- Bad error occured!!!
...
...

I suppose the bug is perhaps in mpt-fusion code because I triggered it
also with two lsi logic cards.

Please tell it to lsi logic developers also!

Thanks again for past and future help!
