Changing the Phy Link Speed
You can change the link speed between the controller and an expander or between the controller and a drive that is directly connected to the controller. Typically, the phy link speed is set to Auto. If desired for compatibility, troubleshooting or performance analysis, you can specify a specific link speed (1.5 or 3.0 Gbps).
To change the phy link speed in 3DM

On the Controller Phy Summary page, identify the phy device for which you wish to change the link speed. Direct-attached drives are identified by their VPort ID.

In the Link Control drop-down menu, select the desired speed: 3 Gbps, 1.5 Gbps, or Auto.
The link speed is now reset.
