Bug Description

== SRU Justification ==
The bug reporter stated that the HBA Emulex LPe12000 Fibre channel adapter
does not see the disk on direct attach. Broadcom support confirmed that bug
and suggested to update module. It was found that commit 2877cbf is the
fix for this bug.

Commit 2877cbf is in mainline as of v4.14-rc1.

== Fix ==
commit 2877cbffb79ed121a6bcc5edbe629d3aba36cd29
Author: Dick Kennedy <email address hidden>
Date: Wed Aug 23 16:55:31 2017 -0700

scsi: lpfc: Fix loop mode target discovery

== Regression Potential ==
Low. Clean cherry pick and only adds a new check for loop mode.

== Test Case ==
A test kernel was built with this patch and tested by the original bug reporter.
The bug reporter states the test kernel resolved the bug.

== Original Bug Description ==
Hi.

I have problem with HBA Emulex LPe12000 Fibre channel adapter. It doesn't see disk on direct attach.

I have made a little investigation.

Ubuntu 16.04.3 LTS, kernel 4.10.0-28, lpfc 11.2.0.2 - no problem.
Ubuntu 17.10.1, kernel 4.13.0-21, lpfc 11.4.0.1 - problem.
Debian 9.3, kernel 4.9.0-4, lpfc 11.2.0.0 - no problem.
Fedora 27, kernel 4.13.9-300, lpfc 11.4.0.1 - problem.
Proxmox 5.0, kernel 4.10.15-1, lpfc 11.2.0.2 - no problem.
Proxmox 5.1, kernel 4.13.13-5, lpfc 11.4.0.1 - problem.

Another user with this problem said that if fiber switch is added between the server and the storage it's working as expected.

I think problem is in lpfc.ko 11.4.0.1. Any kernel (4.13 now) that has this module version is affected. Broadcom support confirmed that bug and suggested to update module. But Broadcom supports only RHEL and SLES. I tried to compile, but no luck. Please, could you update lpfc.ko module in linux-image-generic package?

There are version 11.4.142.21 for SLES 12 and 11.4.204.11 for RHEL 6 and 7 on Broadcom site.

Thanks.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.15 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

I built a test kernel with commit 2877cbffb79. The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1746970

Can you test this kernel and see if it resolves this bug?

Note, to test this kernel, you need to install both the linux-image and linux-image-extra .deb packages.

Thanks in advance!

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-artful' to 'verification-done-artful'. If the problem still exists, change the tag 'verification-needed-artful' to 'verification-failed-artful'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
