User's Manual

On a SCSI controller, the Rescan task rescans the controller connectors to verify the currently connected
devices or to recognize new devices that have been added to the connectors. Performing a rescan on a
connector is similar to performing a rescan on the controller. For information on scheduling a rescan, see
Rescanning To Update Storage Configuration Changes.
NOTE: Rescan is not supported on non-RAID SCSI controllers. Reboot the system before Storage
Management can see configuration changes on non-RAID SCSI controllers. Otherwise,
configuration changes are not reflected in the Storage Management graphical user interface (GUI).
Rescanning A Controller Connector
To rescan a controller connector:
1. In the Server Administrator window, under the system tree, expand the Storage dashboard to display
the controller objects.
2. Expand a controller object.
3. Select a connector object.
4. Click Information/Configuration on the connector Properties page.
5. Select Rescan from the Connector Tasks drop-down menu.
6. Click Execute.
Logical Connector Properties And Tasks
To display the information about the logical connector (connector in redundant path mode) and to
execute connector tasks, use the logical connector properties and tasks page.
The connector properties can vary depending on the model of the controller. Connector properties may
include:
Table 28. Logical Connector Properties

For more information, see Storage Component Severity.
A Warning or Critical severity may indicate that the

devices such as an enclosure. Check the status of
attached devices. For more information, see Cables
