lputil does not discover emulex cards after upgrading to SLES9 SP3

Environment

Novell Open Enterprise Server (Linux based)
SuSE Linux Enterprise Server (SLES) 9 Service Pack 3
Linux Kernel 2.6.5-7.267.smp
Emulex Host Adaptor
Emulex 8.0.16.17 HBA driver
Emulex HBAnywhere

Situation

lputil does not find adapters when run with the 2.0.9-1 ioctl kit (lpfc_2.6_ioctl_inbox-2.0.9-1) and recent (2.6.5-7.265 and above) SLES 9 errata kernels.

Error msg: lpfc driver is not loaded

This error occurred after upgrading the SLES9 SP3 kernel from 2.6.5-7.244-smp to 2.6.5-7.267-smp

The lpfc driver in SLES 9's 2.6.5-7.265 kernel, although named 8.0.16.17, contains a bug fix which includes a modification to lpfc_sli.h. This modification changes the layout of the lpfc_hba structure from what the 2.0.9 ioctl driver expects (because it pulls in the original 8.0.16.17's version of lpfc_sli.h).

Resolution

Upgrade to the 2.0.9-2 ioctl kit (lpfc_2.6_ioctl_inbox-2.0.9-2) using the steps outlined in the Emulex Driver and Utilities for Linux Version 8.0 User Manual

http://www.emulex.com/ts/downloads/linuxfc/rel/801617/pdf/manual.pdf

for Installing the Application Helper Module Kit into an Upgraded Kernel on pages 8-9.

Note

For this example, note that this current server has the 2.6.5-7.267-smp kernel loaded and lpfc_2.6_ioctl_inbox-2.0.9-1 and lputil does not see the adapters:

# uname -a

Now boot into the original kernel that the lpfc_2.6_ioctl_module_kit-2.0.9-1 was installed under.
Note that lputil works again.

Now follow the steps for Installing the Application Helper Module Kit into an Upgraded Kernel.

Step 1) Copy the ioctl-install script to the temporary directory.

# cd /usr/src/lpfcdfc/
L1:/usr/src/lpfcdfc # cp ioctl-install /tmp

Step 2) Execute the ioctl-install script.

L1:/usr/src/lpfcdfc # /tmp/ioctl-install --uninstall

Step 3) Upgrade the kernel and/or distribution.

Example 1: Boot into the new kernel.

L1:/usr/src/lpfcdfc # cd /boot
L1:/boot # rm initrd initrd.previous vmlinuz vmlinuz.previous
L1:/boot # ln -s initrd-2.6.5-7.267-smp initrd
L1:/boot # ln -s initrd-2.6.5-7.244-bigsmp initrd.previous
L1:/boot # ln -s vmlinuz-2.6.5-7.267-smp vmlinuz
L1:/boot # ln -s vmlinuz-2.6.5-7.244-bigsmp vmlinuz.previous
L1:/boot # cd /usr/src
L1:/usr/src # rm linux linux-obj
L1:/usr/src # ln -s linux-2.6.5-7.267 linux
L1:/usr/src # ln -s linux-2.6.5-7.267-obj linux-obj

Example 2: Installing the new kernel-source and new kernel rpms, if you have not already done so.

Step 4) Reboot the system with the new kernel.

L1:/usr/src # reboot

# uname -a
Linux L1 2.6.5-7.267-smp #1 SMP Wed Jun 21 10:50:51 UTC 2006 i686 i686 i386 GNU/Linux

Step 5) Download the Application Helper Module Kit from the Emulex web site or copy it to the system from the installation CD.

Emulex Web Site http://www.emulex.com/

Step 6) Log on as 'root' to a terminal, and unpack the tarball with the following command:

# tar xzf lpfc_2.6_ioctl_module_kit-2.0.9-2.tar.gz

Step 7) Change to the directory that is extracted:

# cd lpfc_2.6_ioctl_module_kit-2.0.9-2

Step 8) Execute the 'lpfc-install' script with no options to install the new driver kit.
