Locking the Network

When you configure (first time configuration) a feature (or application) that uses the CFS infrastructure,
that feature starts a CFS session and locks the network. When a network is locked, the switch software
allows configuration changes to this feature only from the switch holding the lock. If you make
configuration changes to the feature from another switch, the switch 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 network lock but forget to end the session, an administrator can
clear the session. If you lock a network 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.

Committing Changes

A commit operation saves the pending database for all application peers and releases the lock for all
switches.
