Current upstream kernels fail to boot on my POWER8 server with
multipath SCSI disks and IPR host bus adapters. What happens is that
the system finds each disk twice (as normal) and then prints messages
like this:
[2.827761] sd 1:2:4:0: alua: supports implicit TPGS
[2.827875] sd 1:2:4:0: a
t alua can only be used on disks for which scsi_vpd_lun_id() can
produce an identifying string.

I recently tried v4.3-rc2 on a test machine I have which is a POWER8
server with multipath SCSI disks. It failed to boot because it didn't
find its disks. Two things were evident in the logs: first, we're
hitting a WARN_ON_ONCE in the module code:
[1.953020] WARNING: at /home/paulus/kernel/k
)
to prepend "scsi_dh_" to the name, just like the old code in
drivers/md/dm-mpath.c:parse_hw_handler() used to do.

I have the first 3 patches in my queue, so yes I've acked it. It's
probably easiest if the remaining 3 go through my queue once th

Since commit 8d47e65948dd ("dm mpath: remove unnecessary NVMe
branching in favor of scsi_dh checks", 2018-03-05), upstream kernels
fail to boot on my POWER8 box which has multipath SCSI disks. The
host adapters are IPR and the userspace is CentOS 7.
Before that commit, the system booted fine. Af
