Arcserve Backup Cannot Detect the Library

Valid on Windows platforms.

Symptom

Arcserve Backup is unable to detect the library.

Solution

There are several corrective actions that you can use to determine why Arcserve Backup cannot detect the library.

Make sure your computer can detect the library.
You can quickly check to see if your computer can detect the SCSI device by using the following steps.
1. Run regedt32.exe, which is located in the System32 directory under the Windows System directory. The device should be located under:
```
HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\SCSI\SCSI PORT #\SCSI Bus #\Target Id #\Logical Unit Id #
```
2. If SCSI is not listed, your Host Bus Adapter (HBA) is not enabled. Verify that you have installed the proper driver for the HBA.
3. If you do not see a Target ID, Windows did not detect your devices. If Windows cannot detect the devices, Arcserve Backup cannot detect them.
Check to see if your computer detected any problems with the SCSI card. To do so, view the System Log in the Event Viewer, located in the Administrative Tools program group.
Check to see whether your device driver was loaded.

Use the following steps if you are having difficulty with any of the solutions described previously.

Verify that the library power is turned on.
Make sure that all cables are properly attached to the SCSI card.
Verify that no two devices have the same SCSI IDs. For example, libraries with two SCSI IDs will have problems if the Library Unit and Library Drive have the same SCSI IDs.
Ensure that the last device and the first device on the SCSI chain are terminated. See the SCSI card manual for information about SCSI ID and termination issues.
Verify that the library and the board are certified by Arcserve.
Make sure you have the latest driver for the HBA.

After performing these corrective actions, run the Device Configuration utility and reconfigure the library.
