Kernel and Driver Notes
SLES and openSUSE ship lpfc and qla2xxx HBA drivers in the standard kernel. SLES Enterprise subscribers have access to kernel live patching (kGraft) which does not require a reboot when applying kernel updates.
Check running kernel:
uname -rVerify FC modules are loaded:
lsmod | grep -E "lpfc|qla2xxx|bnx2fc"
# Load manually if needed
sudo modprobe lpfc # Broadcom/Emulex
sudo modprobe qla2xxx # Marvell/QLogicMake module load persistent:
echo "lpfc" | sudo tee -a /etc/modules-load.d/fc-hba.conf
# or
echo "qla2xxx" | sudo tee -a /etc/modules-load.d/fc-hba.confPackage Management

systemctl status multipathdYaST Storage Notes
YaST provides a graphical interface for storage management on SLES. For FC storage:
-
can show the multipath device once it is configured
-
For initial FC setup and
multipath.confconfiguration, CLI is recommended - YaST does not expose fine-grained multipath tuning parameters -
After LVM is configured via CLI, YaST can be used to monitor and manage the volume group
