If the device-alias confirm-commit command is enabled, on committing the pending database, the pending-diff is displayed
on the console and user is prompted for Yes or No. If the device -alias confirm-commit command is disabled, the
pending-diff is not displayed and the user is not prompted for Yes or No.
Discarding Changes
If you discard the changes made to the pending database, the following events occur:
1. The effective database contents remain unaffected.
2. The pending database is emptied of its contents.
3. The fabric lock is released for this feature.
To discard the device alias session, perform this task:
Step 1 switch# config terminal
switch(config)#
Enters configuration mode.
Step 2 switch(config)# device-alias abort
Discards the currently active session.
To display the status of the discard 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:
==========================================================

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.
The changes are only available in the volatile directory and are subject to being discarded if the switch is
restarted.
Tip
To clear device-alias session, use the clear device-alias session command in CONFIGURATION mode.
switch(config)# clear device-alias session
