12.11.2 Changing the Backplane Discovery Protocol Setting

A discovery protocol is the connector mode protocol that discovers the attached backplane on the connectors of the Adaptec Smart Storage Controller. Following are the supported backplane discovery protocols in maxView:
  • AutoDetect (With SAS/SATA fallback): The controller firmware attempts to automatically detect the discovery protocol of the backplane attached to the port.
  • SGPIO: The controller firmware uses Serial General Purpose Input/Output (SGPIO) to communicate with the backplane attached to the port.
  • UBM: The controller firmware uses Unified Backplane Management (UBM) protocol to communicate with the backplane attached to the port.
  • VPP: The controller firmware uses the Virtual Pin Port (VPP) protocol to communicate with the backplane attached to the port.
  • Direct-Attached Cable: The controller firmware uses the direct-attached cable protocol to communicate with direct attached drives. Provide the number of targets (drives) that matches the direct attached cable's capabilities. If the number of targets is not configured correctly, target drives may not get discovered.
Note: If the port discovery protocol is not configured correctly, some features of the backplane may not function as expected. A reboot is required for the new port discovery protocol to take effect.
To change the backplane discovery mode protocol settings from the connector level:
  1. In the Enterprise View, select a connector.
  2. On the ribbon, in the Controller group, click Set Properties.

    The Set Properties window opens.

  3. From the Backplanedrop-down menu, change the backplane setting of the connector to SGPIO, VPP, UBM, or Direct-Attached Cable.
  4. Click OK.
  5. Reboot the server.
