Cable the new SAS expansion enclosure

Follow these guidelines to cable an expansion enclosure in a running system to a new expansion enclosure.

Prerequisites

Apply cable labels to the cables connecting the expansion enclosures. In this procedure, "last expansion enclosure" refers to the last expansion enclosure that is currently installed. The "new expansion enclosure" refers to the expansion enclosure that you are adding in this procedure.

NOTE:One cabinet requires four SAS cables, two cabinets requires six SAS cables, and three cabinets require eight SAS cables. Verify that you have the correct amount of cables before you start.
CAUTION: If you observe incorrect cabling between expansion enclosures or to the base enclosure, do not attempt to correct the cable connections. To avoid a potential service disruption, gather support materials and contact your service provider for guidance.
CAUTION: Incorrect cabling could cause all new drives to be locked.

Steps

  1. Disconnect the SAS cable from LCC B, port B of the last expansion enclosure and move it to LCC B, port B of the new expansion enclosure.
  2. Disconnect the SAS cable from LCC A, port B of the last expansion enclosure and move it to LCC A, port B of the new expansion enclosure.
  3. Use a new SAS cable to connect LCC A, port B of the last expansion enclosure to LCC A, port A of the new expansion enclosure.
  4. Use a new SAS cable to connect LCC B, port B of the last expansion enclosure to LCC B, port A of the new expansion enclosure.
