multipathing in CentOS 6.7?
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 | DM multipath kernel driver v1.6.0 Feb 26 02:21:00 | loading /lib64/multipath/libcheckdirectio.so checker 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
