Troubleshooting hardware-related issues in Backup Exec
For common hardware-related issues, review the following frequently asked questions:
Table: Hardware-related questions
| Question | Answer |
|---|---|
| How do I know if my storage device is supported? | You can find a list of compatible devices at the following URL\: |
| http://www.veritas.com/docs/000017788 | |
| If your drive is listed on the hardware compatibility list, run the Configure Storage wizard and install Veritas device drivers. | |
| See Installing Veritas tape device drivers . | |
| From the Configure Storage wizard, the Veritas Device Driver Installation Wizard finds and installs the most suitable driver for your tape drive. | |
| How can I troubleshoot issues with a robotic library or tape drive? | You can find troubleshooting tips and a video tutorial about configuring and troubleshooting tape drive hardware at the following URL\: |

| I'm getting an error "Storage device \[device\] reported an error on a request to read or write data to or from media. Error reported: Data error (cyclic redundancy check)." What should I do? | Many factors can cause the cyclic redundancy check (CRC) error. |
| The following list contains the most common reasons for this error and potential ways to resolve the problem: | |
| - Contaminated read and write heads of the tape device. Check with the hardware manufacturer for proper cleaning techniques. | |
| - Bad media. Replace the media. Try a new tape that the hardware manufacturer has certified. | |
| - Tape driver. Load the appropriate Backup Exec tape driver. You can find a list of compatible devices at the following URL: http://www.veritas.com/docs/000017788 | |
| - Wide negotiation for the SCSI controller is not configured properly. If the device is a wide (68 pin) SCSI device, then wide negotiation may and should be used. If the device is a narrow (50 pin) SCSI device, disable wide negotiation. Use the manufacturer's SCSI installation program to disable wide negotiation on the SCSI controller card. | |
| - SCSI controller transfer rate is too fast. Use the manufacturer's SCSI installation program to lower the SCSI transfer rate. Check with the manufacturer of the controller and the device for the proper configuration for the SCSI transfer rate. | |
| - SCSI controller synchronous negotiation enabled. Use the manufacturer's SCSI installation program to disable synchronous negotiation on the SCSI controller card. Check with the manufacturer of the controller and the device for the proper configuration for SCSI synchronous negotiation. | |
| - Incorrect termination or bad cables. Verify that the SCSI cable is good and that it is configured to provide proper SCSI termination. Do not mix passive and active termination. | |
| - Confirm that the tape drive functions properly. Check with the tape drive manufacturer for diagnostic software to test the condition of the tape drive hardware. | |
| - General SCSI problems. Isolate the tape drive on its own controller card or try a different SCSI card. | |
| Why does my DLT tape drive pause when it catalogs some tapes? | The DLT tape drive maintains internal information about the tape on a tape directory track. The directory track is updated before the tape is ejected from the drive. If the drive is turned off without ejecting the tape first, this information is lost. |
| Re-generating the tape directory information takes several hours to complete, which makes it seem like the drive is hung. Allow sufficient time for the operation to complete and then eject the tape. Normal operation resumes after the directory track is updated. | |
| A backup to my DLT tape drive is stuck at 99% complete. What should I do? | The backup most likely fails to complete because the storage option Eject the media after job completes is selected, and the tape drive does not support the operation. Some tape drives require you to manually remove the tape, such as Digital Linear Tape (DLT), Linear Tape-Open (LTO), Travon, and Onstream drives. |
| To remedy this situation, either uncheck the storage option Eject the media after job completes , or configure an automatic response to the active alert. | |
