Fabric Lock Override

If you have performed a device alias task and have forgotten to release the lock by either committing or
discarding the changes, an administrator can release the lock from any switch in the fabric. If the
administrator performs this task, your changes to the pending database are discarded and the fabric lock
is released.
Tip The changes are only available in the volatile directory and are subject to being discarded if the switch
is restarted.
To use administrative privileges and release a locked device alias session, use the clear device-name
session command in EXEC mode.
switch# clear device-alias session
To display the status of the clear operation, use the show device-alias status command.
switch# show device-alias status

Database:- Device Aliases 24
