Overriding the Fabric Lock

You can use locking operations (clear, commit, abort) only when device alias distribution is enabled. 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.
The changes are only available in the volatile directory and may be discarded if the switch is restarted.
To use administrative privileges and release a locked device alias session, use the clear device-alias session
command in EXEC mode.
switch# clear device-alias session
This example shows how to display the status of the clear operation:
switch# show device-alias status
Fabric Distribution: Enabled
Database:- Device Aliases 24
Status of the last CFS operation issued from this switch:
==========================================================
Operation: Clear Session<--------------------Lock released by administrator
Status: Success<-----------------------------Successful status of the operation

Disabling and Enabling Device Alias Distribution
