This tip is not software specific.

Solution

Check the hard disk drive ID (SGPIO) cable to ensure that it is pushed in correctly in the port on the Expander card and on the Serial Attached SCSI (SAS) backplane.

Additional information

The SGPIO cable contains the sideband signals, which effect the numeration and messaging between the SAS controller and the backplane. It must be firmly seated to ensure electrical continuity.
