Lock Failure Troubleshooting
Resolving Lock Failure Issues Using the CLI
To resolve a lock failure using the CLI, follow these steps:
Step 1 Issue a show cfs lock name command to determine the lock holder. An example of the show cfs lock
name command follows:
Switch# show cfs lock ntp
Application:ntp

--------------------------------------------------------------------
20:00:00:05:30:00:6b:9e 10.76.100.167 admin CLI/SNMP v3

Step 2 For a detailed description of the lock failure, issue the show cfs internal session-history name
application name detail command. Example command output follows:

Step 3 If the lock is being held by a remote peer, an application-name commit command or an
application-name abort command must be executed at that switch. An example of the application-name
commit command follows:
Switch# config terminal
Switch(config)# ntp commit
Switch(config)#
An example of the application-name abort command follows:
Switch# config terminal
Switch(config)# ntp abort
Switch(config)#
