Hello everyone.

I have a computer with a HBA pci card on it (For those who don't know what an HBA is, look here: http://www.webopedia.com/TERM/H/HBA.html In fact it doesn't matter).

I followed the instruction on the driver's manual in order to install and load the device's driver into the kernel, and I get the following error:

[root@lbackha1 network-scripts]# insmod lpfcdd
Using /lib/modules/2.4.21-32.ELsmp/kernel/drivers/scsi/lpfcdd.o
/lib/modules/2.4.21-32.ELsmp/kernel/drivers/scsi/lpfcdd.o: init_module: No such device
Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters.
You may find more information in syslog or the output from dmesg


dmesg drops out these lines:

Emulex LightPulse FC SCSI/IP: 2.01g Osgt: 1.08
PCI: Unable to reserve mem region #1:1000@fceff000 for device 02:03.0
PCI: Unable to reserve mem region #1:1000@fceff000 for device 02:03.0
lpfc pci I/O region is already in use.
a driver for lpfc is already loaded on this system

So apparently, there is another driver already loaded. But I can't see my device!!

I have another computer with the same installation as this one ( RHEL AS 3.0 update 5), but I haven't tried to install and load the driver yet. I tried to install there some application thats works with HBA and I couldn't because it says it doesn't find the proper driver. So, from that i guet that there isn't a lpfc driver built-in in this linux distribution, is there?

Can anyone help me and give me some clue about where the problem might be?

(Warning: My linux knowledge is low, so please take that into account :P)

Thanks a lot

I'm using the same RHEL version (3.0 update5)& running Oracle.
I vaguely remember removing the HBA entries in modules.conf and recompiling the kernel & reboot (without HBA cards installed). Then shutdown and reboot again this time add cards and then add the entries to modules.conf and recompile the kernel one more time. Reboot one last time. This was using q-logic cards. A real pain but it works.

No entries on modules.conf for HBA. There were tqo different ways to load the driver according to the manual. One required adding the following entry to modules.conf:

alias scsi_hostadapter lpfcdd

I noticed that there was another entry for scsi_hostadapter:

alias scsi_hostadapter megaide (that is a driver I loaded in order to use my sata RAID).

Can this be an issue?

I'm sensing that maybe this distro has the required driver for my HBA built-in, because, in other computer with the same installation except for the driver installation I did the following:

[root@lbackha2 root]# lspci -vv

If i get this response from lspci, can I then conclude that the driver needed is already on the kernel?

What I did on my other computer was install the driver from an rpm file, build it as a module and then load it like this:

rpm -i package.rpm
cd intallation directory
make
make install
insmod driver1
insmod driver2

If I am right and the driver is built-in, how can I undo this?

Thanks for your help
