Chapter 41 Managing FLOGI, Name Server, FDMI, and RSCN Databases
RSCN
• A copy of the configuration database becomes the pending database along with the first active
change.
Committing the RSCN Timer Configuration Changes
If you commit the changes made to the active database, the configuration is committed to all the switches
in the fabric. On a successful commit, the configuration change is applied throughout the fabric and the
lock is released.
To commit RSCN timer configuration changes, perform this task:
Discarding the RSCN Timer Configuration Changes
If you discard (abort) the changes made to the pending database, the configuration database remains
unaffected and the lock is released.
To discard RSCN timer configuration changes, perform this task:
Clearing a Locked Session
If you have changed the RSCN timer configuration and have forgotten to release the lock by either
committing or discarding the changes, an administrator can release the lock from any switch in the
fabric. If the administrator performs this task, your changes to the pending database are discarded and
the fabric lock is released.
Tip The pending database is only available in the volatile directory and are subject to being discarded if the
switch is restarted.
To use administrative privileges and release a locked DPVM session, use the clear rscn session vsan
command in EXEC mode. The following example shows how to clear the RSCN session for VSAN 10:
switch# clear rscn session vsan 10
