Rescan - HP P2000 G3 Cli Reference Manual

rescan

Description This command forces rediscovery of disks and enclosures in the storage system. If both Storage
Controllers are online and able to communicate with both expansion modules in each connected
enclosure, this command rebuilds the internal SAS layout information, reassigns enclosure IDs based
on controller A's enclosure cabling order, and ensures that the enclosures are displayed in the proper
order. A manual rescan temporarily pauses all I/O processes, then resumes normal operation. It can
take up to two minutes for the enclosure IDs to be corrected.
A manual rescan may be needed after system power-up to display enclosures in the proper order.
Whenever you replace a drive chassis or controller chassis, perform a manual rescan to force fresh
discovery of all drive enclosures connected to the controller enclosure.
A manual rescan is not needed after inserting or removing disks; the controllers automatically detect
these changes. When disks are inserted they are detected after a short delay, which allows the disks
to spin up
