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:
Command
Step 1
switch# config t
switch(config)#
Step 2
switch(config)# dpvm activate
switch(config)# no dpvm activate
switch(config)# dpvm activate force

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 device pWWNs and VSANs in the active DPVM database. The active DPVM database should
already be available to enable autolearn.
You can delete any learned entry from the active DPVM database when you enable autolearn. These
entries only become permanent in the active DPVM database when you disable autolearn.
