Procedure 3: Checking SAS host connections

Edit online

Check the host connections for your drive by following these steps.

If your server is not communicating with the SAS drive, the problem might be with the SAS cable, the SAS host adapter, or the SAS host adapter setup.

  1. Check whether the tape drive power is ON.
  2. Verify that the SAS cable is connected properly to the server and to the tape drive.
  3. Check whether the parameters for the SAS host adapter installation are correct.
  4. Verify that the SAS host adapter is supported by the tape drive.
  5. Ensure that there is a point-to-point connectivity between the server and the tape drive. SAS connectivity does not support multiple drive connections (daisy-chaining of devices).
Remember:

The maximum SAS cable length that can be used to connect the host adapter to the tape drive varies depending on the type of SAS connection. See Optional features for the maximum cable length that can be used.
