An MD-CLI session in exclusive configuration mode acquires an explicit lock for both the global candidate and running configuration datastores. This is achieved by executing the configure exclusive command (in the implicit configuration workflow) or the edit-config exclusive command (in the explicit configuration workflow).
An explicit lock can also be obtained via:
NETCONF or gRPC sessions. See the 7450 ESS, 7750 SR, 7950 XRS, and VSR System Management Guide for more information.
a private exclusive configuration session. See Exclusive private configuration session for more information.
To view the lock status of the datastores, the following show command is available:
show system management-interface datastore-locks [detail]
The detail option displays information about any model-driven interface session that impacts the datastore locks. MD-CLI read-only sessions, for example, do not impact the datastore locks.
(ro)[/]
A:admin@node-2# show system management-interface datastore-locks detail

The configuration-sessions command displays the same information as the datastore-locks detail command, but for all configuration sessions regardless of whether the session has a lock on the datastore.

A datastore lock that has been acquired by any model-driven session can be administratively removed by using the following admin command:
admin disconnect session-id session-id
For example, to disconnect the MD-CLI session indicated in the preceding show command output, issue the admin command as follows:
[/]
A:admin@node-2# admin disconnect session-id 10
Disconnecting an MD-CLI session (or any model-driven session, including NETCONF and gRPC) that acquired a datastore lock has the following results:
Any uncommitted changes in the candidate configuration datastore are discarded.
The session is terminated.
The explicit lock is released.
