RHEL 7 DM Multipath ignores "user_friendly_names" and lists paths using WWID

Issue

• Why does DM Multipath lists paths with WWID when "user_friendly_names" enabled in multipath.conf?
• RHEL 7 system configured to use default multipath configuration for NETAPP storage with user friendly names enabled however multipath lists paths with WWID:

# cat /etc/multipath.conf:
defaults {
        user_friendly_names yes
}
# multipath -ll
360060e80164c240000014c24000023c3 dm-0 NETAPP  ,LUN C-Mode

• Cisco UCS blade, multipath volumes are only identified by wwid, rather than the user_friendly_names. Multipath bindings file is not being populated. Config looks correct. Need advice on how to resolve multiapth lun naming.
