Your target is not setup for ALUA properly. It says it supports ALUA, but when scsi_dh_alua asks about the ports it is reporting there are none.

If that fails, then we forget to do device_del before doing the return. My patch in this thread added that back, so we do not see the sysfs oopses anymore. But..... > > 2. It looks like in older kernels, we would allow misconfigured targets like this one to still setup devices. Do we want that old behavior back? > Should we just ignore the return value from scsi_dh_add_device above? > Note that in this case, it is LIO so it can be easily fixed on the target side by just setting it up properly. I do not think other targets would hit this type of issue. > > This has been fixed up with my patchset to update the ALUA handler, most notably the commit 'scsi: ignore errors from scsi_dh_add_device()' which was included in 4.5.
