switch(config-dpvm-db)# no pwwn 12:33:56:78:90:12:34:56 vsan 101

Step 10 switch(config-dpvm-db)# no device-alias device1 vsan 102
(Optional) Removes the specified device-alias mapping from the DPVM config database.
Activating DPVM Config Databases
When you explicitly activate the DPVM config database, the DPVM config database becomes the active
DPVM database. Activation may fail if conflicting entries are found between the DPVM config database and
the currently active DPVM database. However, you can force activation to override conflicting entries.
To disable DPVM, you must explicitly deactivate the currently active DPVM database by issuing the no
dpvm activate command.
To activate the DPVM config database, follow these steps:
Step 1 switch# config t
switch(config)#
Enters configuration mode.
Step 2 switch(config)# dpvm activate
Activates the DPVM config database.
Step 3
switch(config)# no dpvm activate
Deactivates the currently active DPVM database.
Step 4 switch(config)# dpvm activate force
Forcefully activates the DPVM config database to override conflicting entries.

About Autolearned Entries

The DPVM database can be configured to automatically learn (autolearn) about new devices within each
VSAN. The autolearn feature can be enabled or disabled at any time. Learned entries are created by populating
