 DESCRIPTION
 -----------
 The `lttng disable-channel` command disables one or more channels
-previously enabled by the man:lttng-enable-channel(1) command.
+previously enabled with the man:lttng-enable-channel(1) command
+which belong to:
+
+With the option:--session='SESSION' option::
+    The recording session named 'SESSION'.
+
+Without the option:--session option::
+    The current recording session (see man:lttng-concepts(7) to learn
+    more about the current recording session).
+
+See man:lttng-concepts(7) to learn more about channels.
 
-A channel is always contained in a tracing session
-(see man:lttng-create(1) for creating a tracing session). The
-session in which a channel is disabled using `lttng disable-channel` can
-be specified using the option:--session option. If the option:--session
-option is omitted, the current tracing session is targeted.
+The `disable-channel` command disables one channel per 'CHANNEL'
+argument.
 
-Note that re-enabling a disabled channel once its tracing session
-has been active at least once is currently not supported.
+As of LTTng{nbsp}{lttng_version}, you may :not: enable a disabled
+channel once its recording session has been started (see
+man:lttng-start(1)) at least once.
 
+See the ``<<examples,EXAMPLES>>'' section below for usage examples.
