For reference, I just installed multipath on CentOS:
# cat /etc/redhat-release
CentOS Linux release 7.5.1804 (Core)
# rpm -q device-mapper-multipath
device-mapper-multipath-0.4.9-119.el7_5.1.x86_64
# lsblk

dev protocol
sda scsi:unspec
# man multipath.conf
...
blacklist section
...
protocol Regular expression of the protocol to be excluded. See below for
a list of recognized protocols
...
The protocol strings that multipath recognizes are scsi:fcp, scsi:spi, scsi:ssa,
scsi:sbp, scsi:srp, scsi:iscsi, scsi:sas, scsi:adt, scsi:ata, scsi:unspec, ccw, cciss,
nvme, and
undef. The protocol that a path is using can be viewed by running multipathd show
paths format "%d %P"
My version:
device-mapper-multipath-0.4.9-119.el7.x86_64
yours:
device-mapper-multipath-0.4.9-119.el7_5.1.x86_64
So this is quite new.
After a yum update it's much 'better':
~$ sudo multipathd show paths format "%d %P"
dev protocol
sddi scsi:unspec
sddj scsi:unspec
sda scsi:unspec
sdc scsi:unspec
sdd scsi:unspec
But as it's not in the blacklist_exceptions, that's what I will need to add.
