Page 217 Symptom DVD or external SCSI drive fails to boot or is not responding to commands. Action Test the response of the drive(s) to the probe-scsi-all command as follows: 1. At the system ok prompt, type: ok reset-all ok probe-scsi-all 2. Use the test command to gather more information, type: ok test scsi If the system has more than one SCSI disk, you must specify an address.
