Chapter 39 Distributing Device Alias Services
Device Alias Databases
Fabric Lock Override
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.
Tip
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
To display the status of the clear operation, use the show device-alias status command.
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
