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 Gbps, 3.0 Gbps, or 6.0 Gbps).
To change the phy link speed in 3DM2

1 | 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.

2 | In the Link Control drop-down menu, select the desired speed: 6 Gbps, 3 Gbps, 1.5 Gbps, or Auto.

3 | A reboot is required to reset the link speed to the new setting.

| Caution: Restricting the link speed to a higher setting will not allow slower devices to be recognized by the firmware.

For details about the information displayed on this screen, see Controller Phy Summary page.
