Channel Troubleshooting Procedure

This procedure should be used when there is a problem on the SCSI channel outboard of the adapter/controller that prevents the adapter/controller from communicating with the devices attached to that channel.

1.  For non-hot-swap systems, check termination of identified channel.
2.  Check for proper cabling configuration in systems that use DASD status cables.
3.  To determine if a single drive is causing the failure, disconnect one  drive at a time and reboot the system each time.
    Continue until you have  disconnected all the drives, or the failure has disappeared.
4.  Replace SCSI cable.
5.  Replace SCSI backplane.
