If each disk has an activity LED but not an addressable fault
LED, you can run
dd if=/dev/sdX of=/dev/null
to keep the activity LED lit for a while.
Addressable fault LEDs usually have a manufacturer-specific tool
to turn them on and off; this is generally controlled by a RAID
controller utility or an enclosure-specific utility.
