ClearFoundation

ok, drivers are installed. poking and prodding around a bit to see if i could get it done but no such luck yet as the link_state is down. I tried echo UP > link_state as shown in the Emulex manual but i get a write error: Invalid argument.

From what i gathered from the manual, its properties are stored in files and any changes to them are immediate. Maybe i have to <mount -xxxx> the directory (i forget the command), i ran into this once before where wasnt able to edit a file because the file system wasnt writable.

One question i have aside from, any advice, is, why arent fiber nics treated the same way copper nics are? I would think that you should be able to do an ifconfig and see the interfaces like copper and edit as such. why the special treatment?

I've never used fiber optic equipment either, so I may not be able to help you very much. If you post exactly how you installed the driver, someone may be able to help you more.

Do you know the exact name of the kernel module (driver) that the card uses? If you do, you could try:



to load the driver.

Addendum:

I found this link:

www.freelinuxtips.com/emulex-hba-driver/...hba-driver-in-linux/

It may help you.

I downloaded the latest drivers for RHEL 6.2 elx-lpfc-dd-rhel6-8.3.5.68 inside that there is a file called elx_lpfc_install.sh but it wont install from that because it says that it cant detect the distribution type so i extracted tar file: lpfc-rhel6-8.3.5.68-1.tar.gz

Then inside that it contained a rpm called kmod-elx-lpfc-8.3.5.68_2.6.32_131.0.15.el6-1.x86_64.rpm so i did a yum install kmod-elx-lpfc-8.3.5.68_2.6.32_131.0.15.el6-1.x86_64.rpm

it seemed to install and i did a reboot, nothing showed up on the interfaces of ClearOS so thats why i started to dig around a little more.

Try:

modprobe lpfc

tried that, in the emulex manual it refers to a modprobe.conf, no such file exists for me. i put in your command and nothing was spit back to me, i checked the link status of both hosts and link was still down.

Thanks for the help, if you can think of anything else, i would appreciate it.

I have found cases where modprobe failed to find the module - try this just in case

updatedb && insmod `locate lpfc.ko`

then, when it finishes, run

lsmod | grep lpfc

Note the "back ticks" normally just to the left of the number 1 key (usually also has ~ as a shift)
the first command line may take a few minutes - so be patient..

modprobe.conf is no longer used with Version 6 so that manual is presumed for Version 5

thanks tony, when i tried ( updatedb && insmod `locate lpfc.ko` ) that it gives this error: should i remove it and run the command again?

insmod: error inserting '/lib/modules/2.6.32-131.0.15.el6.x86_64/extra/elx-lpfc/lpfc.ko': -1 File exists

for the sake of it i tried the other part of the command ( lsmod | grep lpfc ) just to see what it would do since the file exists and this is what it says:

lpfc 665523 0
scsi_transport_fc 55235 1 lpfc



I checked dmesg again and now that the drivers are installed it shows this that i didnt notice before:

if that helps any

OK - a lpfc.ko driver is loaded - but with all the rpms you installed we don't know which one...

In fact I just looked at my ClearOS V 6.3 64 bit - and lpfc.ko is there as part of the base install...

Here is the result of modinfo - just the first few lines... for the ClearOS 6.3 Version

ok, maybe i'll start from scratch with a fresh install tomorrow and let you know how things go with that.

Just take it one trial at a time - if the ClearOS provided driver doesn't work - rename it so it doesn't load (make sure it is unloaded first) and install one of the rpms - and if that does work, then remove that rpm before trying the next etc so you know where you are and exactly which is being loaded... One change at a time...

Note that I know nothing about fibre - just had a fair bit of experience compiling and loading modules!
