How to disable native multipath (dm-multipath) in CentOS/RHEL

We no longer intend to use the native RedHat multipathing or dm-multipathing. How can we disable it permanently so that it can not be enabled automatically upon reboot?

To disable the native multipathing on a CentOS/RHEL 6,7 system follow the steps outlined below:

1. Edit /etc/multipath.conf and edit the blacklist{} section:

# vi /etc/multipath.conf
blacklist { 
  devnode *
}

2. Stop multipathd and chkconfig daemon off:

### For CentOS/RHEL 6 ###
# service multipathd stop
# chkconfig multipathd off

### For CentOS/RHEL 7 ###
# systemctl stop multipathd.service
# systemctl disable multipathd.service

3. Rebuild initramfs and remove multipath dracut modules:

# cp /boot/initramfs-$(uname -r).img /boot/initramfs-$(uname -r).img.BAK
# dracut -v -f -o multipath /boot/initramfs-$(uname -r).img $(uname -r)
