# vim /etc/multipath.conf

blacklist {
       devnode "^(ram|raw|loop|fd|md|dm-|sr|scd|st)[0-9]*"
       devnode "^hd[a-z]"
       devnode "^sda$"
}

Or using the WWID of the device:

blacklist {
       devnode "^(ram|raw|loop|fd|md|dm-|sr|scd|st)[0-9]*"
       devnode "^hd[a-z]"
       wwid    "1234567890987654321"
}

# service multipathd reload
