SCSI Device Non Detected Troubleshooting
If one or more SCSI device is not detected during the hardware inventory, check the following:
•
Rerun the test and observe the activity lights, if the SCSI device has them. No activity lights indicate
a drive may not be responding. Replace the affected drive and rerun the test.
•
Check cables and termination to ensure they are correct. Refer to the documentation and the
technical reference label or card which accompany the unit.
•
Check to ensure each device has a unique SCSI ID.
•
Find out whether you have an unsupported SCSI controller.
•
Check to see your ASPI driver software was correctly loaded.
If you locate and correct a difficulty, rerun the DiagTools tests to verify your corrective action.
