Rescanning All Channels

You can tell the controller to scan all disk channels for new or removed disk drives. You can use this option when you install or remove drives. The Rescan temporarily pauses all I/O processes and then resumes normal operation.

If you are using an enclosure with a SEP, the controller will perform a rescan automatically for you. With a SEP, the controller will detect removed drives almost immediately; however, installed drives will be detected after a three-minute delay. This delay is to allow the new drives to spin-up.
