Discarding Changes

If you discard (abort) the changes made to the DPVM pending database, the configurations remain
unaffected and the lock is released.
To discard the DPVM pending database, follow these steps:
Command
Step 1
switch# config t
switch(config)#
Step 2
switch(config)# dpvm abort

Clearing a Locked Session

If you have performed a DPVM 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 DPVM pending database are discarded and the
fabric lock is released.
The DPVM pending database is only available in the volatile directory and is subject to being discarded
Tip
if the switch is restarted.
To use administrative privileges and release a locked DPVM session, use the clear dpvm session
command in EXEC mode.
switch# clear dpvm session
Database Merge Guidelines
