An apparatus comprises at least one processing device. The at least one processing device is configured to identify at least one logical storage device that has a first service level objective and is exhibiting a deficiency in one or more performance metrics, to identify one or more additional logical storage devices each having a second service level objective lower than the first service level objective and not exhibiting a deficiency in the one or more performance metrics, to generate at least one false-positive signal specifying the one or more additional logical storage devices as each exhibiting a deficiency in the one or more performance metrics, and to provide the at least one false-positive signal to at least one host device. The at least one host device is configured to respond to the at least one false-positive signal by throttling input-output operations for the one or more additional logical storage devices.
