You can use locator LEDs to identify the location of storage devices.
Virtual SAN can light the locator LED on a failed device so that you can easily identify the device. This is particularly useful when you are working with multiple hot plug and host swap scenarios.
Consider using I/O storage controllers with pass-through mode, because controllers with RAID 0 mode require additional steps to enable the controllers to recognize locator LEDs.
For information about configuring storage controllers with RAID 0 mode, see your vendor documentation.
