 **Description:** Flushes all dirty data from the cache device to all the
 associated core devices.
 
 **Required Parameters:**
 
-**[-i, -\-cache-id \<ID\>]:** Unique identifier for cache \<1 to 16384\>.
-
--  You can interrupt the blocking -\-flush-cache operation by pressing CTRL-C.
-    When dirty data exists, interrupting the operation prior to the cache being
-    fully flushed will result in some dirty data remaining in the cache. The
-    dirty data will be flushed opportunistically as normal. IO to the device
-    will continue with reduced performance during cache flushing.
