Comment 22 for bug 1567602

Just to be sure I did a cross check on my lpar:

Cleaning my system to get an empty condition at the start
sudo chzdev zfcp-lun --all --disable --force
sudo chzdev zfcp-host --all --disable --force
sudo chzdev zfcp --all --disable --force

Now it looks like the one from Thorsten:

ubuntu@s1lp5:~$ lsluns -a
ubuntu@s1lp5:~$ lsmod |grep scsi_dh

Then following Thorstens guide to trigger on live system
1. the one without alua being ok:
ubuntu@s1lp5:~$ sudo chccwdev -e 0.0.e000
Setting device 0.0.e000 online
Done
ubuntu@s1lp5:~$ lszfcp -D

2. the one after loading alua with issues:
ubuntu@s1lp5:~$ sudo modprobe scsi_dh_alua
ubuntu@s1lp5:~$ lsmod |grep scsi_dh
scsi_dh_alua 20480 0
ubuntu@s1lp5:~$ sudo chccwdev -e e100
Setting device 0.0.e100 online
Done
ubuntu@s1lp5:~$ lszfcp -D

dmesg also good with alua on for the second adapter being enabled => http://paste.ubuntu.com/15951140/

So I can confirm Stefans summary.

Thorsten please try to reproduce on a fully updated system, if not resolved for you we have to start to sort out the remaining differences in our environment.
