the enabled/disabled state, timeout as registered with CFS, merge capability (if it has registered with
CFS for merge support), and lastly the distribution scope.

Locking the Fabric
When you configure (first time configuration) a Cisco SAN-OS feature (or application) that uses the CFS
infrastructure, that feature starts a CFS session and locks the fabric. When a fabric is locked, the Cisco
SAN-OS software does not allow any configuration changes from a switch, other than the switch holding
the lock, to this Cisco SAN-OS feature and issues a message to inform the user about the locked status.
The configuration changes are held in a pending database by that application.
If you start a CFS session that requires a fabric lock but forget to end the session, an administrator can
clear the session. If you lock a fabric at any time, your user name is remembered across restarts and
switchovers. If another user (on the same machine) tries to perform configuration tasks, that user's
attempts are rejected.

Verifying CFS Lock Status

The show cfs lock command displays all the locks that are currently acquired by any application. For
each application the command displays the application name and scope of the lock taken. If the
application lock is taken in the physical scope, then this command displays the switch WWN, IP address,
user name, and user type of the lock holder. If the application is taken in the logical scope, then this
command displays the VSAN in which the lock is taken, the domain, IP address, user name, and user
type of the lock holder.
