There was a discussion about this quite recently [1]; reading this might
be inserting, too. The reason for this is the general 'to fit everyone'
approach of the default multipath.conf.

You can blacklist everything, no problem. But you need make some changes
to your mulipath.conf. Please just add the lines and do not remove or
disable any services:
to the second line (2) in multipath.conf, add
# RHEV PRIVATE
to keep host-deploy from overwriting the file.
Then, somewhere in the file:
blacklist {
devnode "*"
}
Then, you need to run:
multipath -d -v3
to test (it should now list all devices as blacklisted) and if successful:
multipath
Effectively blacklisting everything while dm-multipah continues to run.
Please note, if you are running oVirt node, you also need to run
persist /etc/multipath.conf
Also, you have to do this on every host in your data centers naturally.
