About DPVM Databases

The DPVM database consists of a series of device mapping entries. Each entry consists of a device
pWWN or nWWN assignment along with the dynamic VSAN to be assigned. You can configure a
maximum of 16,000 DPVM entries in the DPVM database. This database is global to the whole switch
(and fabric) and is not maintained for each VSAN.
The DPVM feature uses three databases to accept and implement configurations.

Changes to the DPVM config database are not reflected in the active DPVM database until you activate
the DPVM config database. Changes to the DPVM pending database are not reflected in the config or
active DPVM database until you commit the DPVM pending database. This database structure allows
you to create multiple entries, review changes, and let the DPVM config and pending databases take
effect.
