Configuring SDV

SDV is a distributed service and uses Cisco Fabric Services (CFS) distribution to synchronize the databases. When you configure SDV, it starts a CFS session and locks the fabric. When a fabric is locked, Cisco NX-OS software does not allow any configuration changes from a switch other than the switch holding the lock and issues a message to inform users about the locked status. Configuration changes are held in a pending database for the application. You must perform a commit operation to make the configuration active and to release the lock for all switches.

Refer to the Cisco MDS 9000 Family NX-OS System Management Configuration Guide for more details about CFS.

Note     When you enable SDV, CFS distribution is also enabled; CFS distribution cannot be disabled for SDV.
