[dm-devel] RHEL 6: Missing /dev/mpath directory



Hi,
Apologies, as I am not sure whether my query fits into this mailing list. If not, then please direct me to the correct mailing list.

I have configured RHEL 6 X86_64 host and have enabled multipath. As per the DM Multipath documentation at "http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/DM_Multipath/mpath_devices.html#multipath_device_id", 

"When new devices are brought under the control of DM-Multipath, the new devices may be seen in three different places under the /dev directory: /dev/mapper/mpathn, /dev/mpath/mpathn, and /dev/dm-n. "

In my host I am seeing the devices only as /dev/dm-n and /dev/mapper/mpathx symlink to /dev/dm-n. I am not seeing directory /dev/mpath.

Am I missing something in configuring multipath? Please assist in this regard.
