rescan
Description
This command forces rediscovery of attached disk drives and enclosures. If both
Storage Controllers are online, it also forces re-evaluation of the enclosure IDs of
attached drive enclosures, so that IDs are assigned based on controller A’s enclosure
cabling order. A manual rescan may be needed after system power-up to display
enclosures in the proper order.
A manual rescan is not required to detect when drives are inserted or removed; the
controllers do this automatically. When drives are inserted they are detected after a
short delay, which allows the drives to spin up.
When you perform a manual rescan, it temporarily pauses all I/O processes, then
resumes normal operation.
