Trying to configure multipathing on CentOS 6.7. Running into an issue where no multipath devices are found.

[root@hp4 ~]# /sbin/mpathconf --enable --find_multipaths y --user_friendly_names y --with_chkconfig y --with_multipathd y

[root@hp4 ~]# /sbin/mpathconf
multipath is enabled
find_multipaths is enabled
user_friendly_names is enabled
dm_multipath module is loaded
multipathd is chkconfiged on

[root@hp4 ~]# multipath -ll -v2
Feb 26 02:21:00 | No configuration dir '/etc/multipath/conf.d'
Feb 26 02:21:00 | libdevmapper version 1.02.95-RHEL6 (2015-09-08)

Feb 26 02:21:00 | loading /lib64/multipath/libprioconst.so prioritizer

Getting hundreds of the following type of messages:
Found duplicate PV RHrVb09aBGWLL0tw2PkahBFcemSNhxRE: using /dev/sdft not /dev/sdo

There are no luns under /dev/mapper.

What type of storage do you have? Is it in your multipath config file?

Using Clarrion, and yes I have the clarion device entry in the multipath.conf file
