Kernel and Driver Notes

Debian and Ubuntu ship the lpfc and qla2xxx HBA drivers in the standard kernel. No out-of-tree packages are typically required.

Check running kernel:

uname -r

Verify FC modules are loaded:

lsmod | grep -E "lpfc|qla2xxx|bnx2fc"

# Load manually if not autoloaded after HBA is installed
sudo modprobe lpfc    # Broadcom/Emulex
sudo modprobe qla2xxx # Marvell/QLogic

Make module load persistent:

echo "lpfc" | sudo tee -a /etc/modules
# or
echo "qla2xxx" | sudo tee -a /etc/modules

sudo apt update
sudo apt install -y \
