rescan

Description

This command forces rediscovery of attached disks and enclosures. If both Storage Controllers are

online this command also reassigns enclosure IDs 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 disks are inserted or removed; the controllers do this

automatically. When disks are inserted they are detected after a short delay, which allows the disks

to spin up.

When you perform a manual rescan, it temporarily pauses all I/O processes, then resumes normal

operation.

Syntax

rescan

Example

Scan for device changes and re-evaluate enclosure IDs:

# rescan
