Setting the preferred path for a LUN (Preferred Path)

NOTE:

This task is available for dual-controller configurations only.

To manually (explicitly) set controller ownership of a LUN:

Select an already-configured logical drive from the system component list, and then select the

Preferred Path task.

Expand the Preferred Path drop-down box and select a controller.

IMPORTANT:

If the Redundancy Setting mode is set to “Automatic”, path ownership may automatically switch

from one controller to the other, depending on the processing load, as the system attempts

to balance the processing load between the two controllers. To permanently set the path for

a LUN, the Redundancy Setting mode must be set to ’Manual”. For more information, see
