The SAS device cable might be failing.

If the device is an internal device (not in an external disk expansion unit), there is no cable. Continue with the next failing item in the failing item list. This ends the procedure.

If the device is in an external expansion unit, ensure the cables are connected correctly. If they are not connected correctly, fix the cable connection problem. If they are already connected correctly, replace the cables. See the Site and Hardware Planning Guide, order number SA76-0091 for cable FRU part numbers. This ends the procedure.
