About Locking the Fabric
The first action that modifies the existing configuration creates the DPVM pending database and locks the
feature in the fabric. Once you lock the fabric, the following conditions apply:
• No other user can make any configuration changes to this feature.
• A copy of the configuration database becomes the DPVM pending database. Modifications from this
point on are made to the DPVM pending database. The DPVM pending database remains in effect until
you commit the modifications to the DPVM pending database or discard (abort) the changes to the DPVM
pending database.
