Channel Tasks: Rescan Channel

This task rescans the controller channels to verify the currently connected devices or to recognize new devices that have been added to the channels. Performing a rescan on a channel 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.

On non-RAID SCSI controllers, the operating system must be able to see any hardware changes before initiating the controller rescan. Otherwise, the hardware changes may not be reflected in the Storage Management graphical user interface (GUI). Refer to the operating system documentation for information on updating hardware changes. You can also reboot the system to update hardware changes with the operating system.

Do the following to rescan a controller channel:

Expand the Storage tree object to display the controller objects.
Expand a controller object.
Select a channel object.
Select the Information/Configuration subtab.
Select Rescan from the Available Tasks drop-down menu.
Click Execute.
