|Fixed In Version:||device-mapper-multipath-0.4.9-59.el6||Doc Type:||Bug Fix|
Cause: On reload, if a multipath device wasn't set to use user_friendly_names or a user defined alias, multipath was using it's existing name instead of setting it to the wwid Consequence: Disabling user_friendly_names did not cause the multipath device names to change back to wwids on reload. Fix: multipath now sets the device name to its wwid if no user_friendly_names or user defined aliases are set. Result: Disabling user_friendly_names will now allow device names to switch back to wwids on reload.

Fixed. Device names will now switch back to WWIDS on reload.
Comment 10 Gris Ge 2013-01-22 04:16:01 UTC
VERIFY device-mapper-multipath-0.4.9-63.el6.x86_64 service multipathd reload will rename mpath if user_friendly_name changed.
