User's Manual

Does my controller support this feature? See "Supported Features."
On a SCSI controller, this 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 when you may want to do a
rescan, see "Rescan to Update Storage Configuration Changes."
Do the following to rescan a controller connector:

1. Expand the Storage tree object to display the controller objects.

2. Expand a controller object.

3. Select a Connector object.

4. Select the Information/Configuration subtab.

5. Select Rescan from the Available Tasks drop-down menu.

6. Click Execute.

Connector Components
For information on attached components, see the following topic:
l "Enclosure and Backplane Properties and Tasks"
Logical Connector Properties and Tasks
Use this window to view information about the logical connector (connector in redundant path mode) and to execute connector tasks.

Logical Connector Properties
The connector properties can vary depending on the model of the controller. Connector properties may include:

Path Health
The path health of the connectors is represented as normal, warning, or critical. The possible values are displayed as Available, Degraded, or Failed.
If the enclosure health is displayed as degraded and further investigation shows all enclosure components (EMMs, Fans, Physical Disks, Power Supplies, and
Temperature) to be in normal condition, select the Information/Configuration subtab of the enclosure to view details of the Path Failure.
NOTE: Rescan is not supported on non-RAID SCSI controllers. You must 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).

Property

Definition
These icons represent the severity or health of the storage component. See "Storage Component Severity" for more information.
A Warning or Critical severity may indicate that the connector is unable to communicate with attached devices such as an enclosure. Check
the status of attached devices. See "Cables Attached Correctly" and "Isolate Hardware Problems" for more information.
Name
This property displays the connector number, usually 0.
State
This property displays the current status of the connector. Possible values are:
Ready — The connector is functioning normally.
Degraded — The connector has encountered a failure and is operating in a degraded state.
Failed — The connector has encountered a failure and is no longer functioning.
Connector
Type
This property displays whether the connector is operating in RAID mode. The connector will always be a SAS connector.
