CentOS 6.4 (amd64) stock kernel. HBA FC Accusys ACS 63200NT

I built the driver from source, insmod activates the device and I can see the 24 TB storage volume via 'parted --list' I have created a XFS files system and mounted it under /srv/

Where do I need to install the driver in /lib/modules/ ... directory tree so that it is loaded automatically when the system boots?

TIA,

If your module is replacing a driver already in the kernel tree then it should go in /lib/modules/$(uname -r)/updates/

It is not present in the stock kernel.

If it's a new driver not present in the kernel then it should go in /lib/modules/$(uname -r)/extra/

Thanks - I was not sure of where to copy the driver.

and then run 'depmod -a'

Yes, I knew this has to be done to build the dependency list after putting the driver file in the proper directory

BTW, you should use modprobe and modprobe -r to load and unload modules rather than insmod as modprobe understands module dependencies whereas insmod doesn't.

I tried modprobe first to insert the driver but it kept saying module not found. insmod ./<driver_file_name> worked.

I believe, modprobe will work if the driver is in the /lib/modules/$(uname -r)/ tree and the depmod has been done.

Gracias,
