Incorrect driver getting loaded for Qlogic FC-HBA

Incorrect driver getting loaded for Qlogic FC-HBA

[Rajat Jain]

Hi,

I do not know which list to put this problem on. And hence ...

I'm using Kernel 2.6.9 and am having a Qlogic QLE2362 FC-HBA in my
system. I selected all the Qlogic SCSI drivers while buiding the
kernel. Now the problem is that every time I reboot, I have to
MANUALLY modprobe the qla2322.ko module in the kernel and only then my
HBA works. By default, the kernel loads qla2300.ko, which is not the
correct driver for the card, and hence the HBA does not work. Here is
the lspci output:

-----------------------------------------------------------------
0d:07.1 Fibre Channel: QLogic Corp.: Unknown device 2322 (rev 03)
	Subsystem: QLogic Corp.: Unknown device 0118
	Flags: bus master, 66Mhz, medium devsel, latency 128, IRQ 185
	I/O ports at 6400 [size=256]
	Memory at d0401000 (64-bit, non-prefetchable) [size=4K]
	Capabilities: [44] Power Management version 2
	Capabilities: [4c] PCI-X non-bridge device.
	Capabilities: [54] Message Signalled Interrupts: 64bit+ Queue=0/3 Enable-
-------------------------------------------------------------------

Here is the relevant extract from modules.pcimap:
-------------------------------------------------------------------
#module  vendor     device     subvendor  subdevice  class     
class_mask driver_data
qla2300  0x00001077 0x00002300 0xffffffff 0xffffffff 0x00000000 0x00000000 0x0
qla2300  0x00001077 0x00002312 0xffffffff 0xffffffff 0x00000000 0x00000000 0x0
qla2322  0x00001077 0x00002322 0xffffffff 0xffffffff 0x00000000 0x00000000 0x0
-------------------------------------------------------------------

As can be seen from above, qla2322 is the correct driver for device
2322 (My QLE2362 HBA has a device no 2322, as seen in lspci output).
But for some reason the kernel always loads qla2300 instead on
qla2322. I even tried putting the "qla2322" line on top of the two
"qla2300" lines in the modules.pcimap file. But with no result.

TIA,

Rajat

"by default" the kernel does not load any modules.  That's up to the
hotplug system, or some other package.

Thanks. I just checked .. that is right. So let me put it this way.
When ever I hot-plug my HBA into the system, the driver "qla2300" gets
loaded. Where as the correct driver is "qla2322". This evident from
the output of "modules.pcimap" file and "lspci". The PCI device number
of HBA is 2322. and in modules.pcimap file, qla2322 is supposed to be
loaded when this HBA is hot-plugged. But module qla2300 is getting
loaded.

Any pointers on where could the problem be? Or how should I approach
this problem?

Thanks a lot.

A similar problem was noted with RHEL4, it seems the modules.pcimap
and pci.ids file were correct, but the pcitable file contained entries
for all ql[ae]23xx based HBAs to load qla2300.ko.

It's my understanding that this was fixed for RHEL4 U1.  Which distro
are you using?  If you are using RHEL, and are still having problems,
I'd suggest you file a report with Redhat.

BINGO! I AM using RHEL 4. So does that mean I can rectify the problem
by making appropriate changes to "pcitable" file?

Thanks a Ton !

I'm trying to get a firm answer from the folks who originally
discvoered the problem some time back, it seems you have two options:

 - during installation of RHEL4 (and not RHEL4U1), load with the
   'noprobe' option:

	linux noprobe

   and manually select the appropriate drivers to load.

 - (post installation) modify the /etc/modprobe.conf to and rename the
   qla2300 entry to qla2322 (i.e.):

	alias scsi_hostadapter1 qla2322

   modify the modules.pcimap table to load qla2322 for the 2322
   device-id:

	qla2300		0x00001077	0x00002322	...

   to:

	qla2322		0x00001077	0x00002322	...


Beyond that, I'd suggest you log a report with Redhat, as that's the
extent of the workaround knowledge without going to RHEL4U1.

Hope this helps,

Hey Thanks. I would really appreciate if you could update list/me on
it IF you get any updates (I know its too much pain).

THANKS. It worked for me, for time being. 
In the mean time, I plan to file  report with RedHat and will update
list as and when I get any response.
