Distribution Status Verification
System State Inconsistent and Locks Being Held
An inconsistent system state occurs when locks are not held on all of the switches in the fabric, or when
locks are held on all switches in the fabric, but a session does not exist with the lock holding switch. In
either case, it may be necessary to use the clear option to release the locks.
Clearing Locks Using Fabric Manager
To clear a lock using Fabric Manager, follow these steps:
Step 1 Select the CFS tab for the application that you are configuring and view the Master check box to identify
the master switch for that CFS application. For example, choose Fabricxx > All VSANS > DPVM and
select the CFS tab.
Step 2 Set the Config Action drop-down menu on the master switch to clear and click Apply Changes to free
the CFS lock.
Clearing Locks Using the CLI
When a lock is being held on a remote peer and issuing the application-name commit command or the
application-name abort command does not clear the lock, issue the clear application-name session
command to clear all locks in the fabric. After all locks are cleared, a new distribution must be started
to restore all the switches in the fabric to the same state.
Example command output follows:
Switch# clear ntp session
Switch# config terminal
Switch(config)# ntp commit
Switch(config)#
Distribution Status Verification
After configuring an application and committing the changes, you may want to verify that CFS is
distributing the configuration change throughout the fabric or VSAN.
Verifying Distribution Using Fabric Manager
In Fabric Manager, choose the CFS tab for the application that you are configuring and check the Last
Results field to view the distribution status for your latest commit.
Verifying Distribution Using the CLI
In the CLI, use the show cfs lock name application-name command to determine if a distribution is in
progress on the fabric. If the application does not show in the output, the distribution has completed.
Example command output follows:
