Fabric Lock Override

If you have performed a Call Home task 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.
The changes are 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 Call Home session, use the clear callhome session
command.
switch# clear callhome session

Be aware that the merged database contains the following information:
A superset of all the destination profiles from the dominant and subordinate switches take part
–
in the merge protocol.
The e-mail addresses and alert groups for the destination profiles.
–
Other configuration information (for example, message throttling, periodic inventory) from the
–
switch that existed in the dominant switch before the merge.
Verify that two destination profiles do not have the same name (even if they have different
configuration information) on the subordinate and dominant switches. If they do contain the same
name, the merge operation will fail. You must then modify or delete the conflicting destination
profile on the required switch.
