Discarding Changes

If you discard (abort) the changes made to the pending database, the configurations remains unaffected
and the lock is released.
To discard the 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 pending database are discarded and the fabric lock
is released.
The pending database is only available in the volatile directory and are subject to being discarded if the
Tip
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

A database merge refers to a union of the configuration database and static (unlearned) entries in the
active database. See the
When merging the database between two fabric, follow these guidelines:
•
•
If you do not follow these two conditions, the merge will fail. The next distribution will forcefully

synchronize the databases and the activation states in the fabric.

Copying DPVM Databases

The following circumstances may require the active database to be copied to the config database:
•

Verify that the activation status and the auto-learn status is the same is both fabrics.
Verify that the combined number of device entries in each database does not exceed 16K.
If the learned entries are only added to the active database.
If the config database or entries in the config database are accidently deleted.
Purpose
Enters configuration mode.
Discards the database entries that are currently in the pending
database.
