If the Oracle FS System remained in production for the Drive Enclosure add procedure, you can use the beaconing feature to ensure that you are working with the correct Drive Enclosure before disconnecting any cables. The beaconing feature in Oracle FS System Manager (GUI) or in Oracle FS CLI (FSCLI) helps you locate Drive Enclosures in a rack and to double check which Drive Enclosures are connected during each step of adding a Drive Enclosure.
During the beaconing process, the system flashes the LEDs on the specified Drive Enclosure. The flashing LEDs help you locate the Drive Enclosure in the rack and determine the cabling connection.
