Unloading the FC and FCoE driver on
SLES 11 SPx may cause a message to be
logged in the system log such as the
following:
umount:
/dev/disk/bypath/pci-0000:02:
04.0-scsi-0:0:1:0: not
mounted
These messages are normal output from the SLES 11 SPx
hotplug scripts and can be safely ignored.
Driver installation fails. The lpfc-install script fails to install the driver. The install
script may fail for the following reasons:
• A previous version of the driver is installed. Run the
lpfc-install --uninstall script and then try to install the
driver.
• The current driver is already installed.
• Run a supported RHEL or SLES kernel.
“No module lpfc found for kernel
KERNELVERSION” RPM error message
when upgrading the kernel. These three situations can be resolved by upgrading the kernel.
There are two ways to install the driver into an upgraded
kernel. The method you use depends on whether you are
updating the driver.
• Upgrade the kernel using the same version of the driver.
• Upgrade the kernel using a new version of the driver.
See chapter 2., “Installing and Uninstalling,” on page 816 for
these procedures.
A recently upgraded kernel cannot find
the ramdisk. After upgrading the
kernel, the kernel cannot find the
ramdisk, which halts or panics the
system.
The driver is not loaded after a system
reboot after upgrading the kernel.
Driver uninstallation fails. The lpfc-install --uninstall script fails with an error.
Try the following solutions:
• Uninstall the OneCommand Manager application; see the
OneCommand Manager Application User Manual for
instructions.
• Unmount all FC disk drives.
• Unload the lpfcdfc and FC and FCoE driver.
• Use rpm -e lpfcdriver and -e ocmanager and uninstall the
new kits.
lpfc-install script exit code. The lpfc-install script contains exit codes that can be useful in
diagnosing installation issues. See the lpfc-install script for a
complete listing of codes and definitions.
