Software Checking; Verifying Recent Changes - Tandberg Data StorageLoader Installation And User Manual

6. Verify that the SCSI cables are properly connected at both ends. Check that the cables are
not damaged, and verify the lengths of your SCSI cabling. The length of the internal SCSI
cabling inside the loader is 15cm. This length must be included in any calculation of cable
length.
7. Verify that the SCSI bus is properly terminated. Only the devices physically at the beginning
and end of the cable must be terminated.

8.3. Software checking

1. Verify that the controller can see all devices during boot sequence. If not, enter HBA-bios
(Host Bus Adapter) and check that LUN-scanning is enabled. It might be disabled by default.
2. Verify that the operating system can see all devices, both robotics and tape drives.
3. Verify that drivers are loaded properly. Some applications use their own drivers so the device
should appear "unknown" in the device manager. Drivers from the hardware vendor should
normally be preferred.
4. Verify that the Backup software detects loader and drives properly and does not report errors.
Run "Device Configuration Wizard" again if needed.

8.4. Verifying Recent Changes

If the StorageLoader has been installed previously and operating correctly but is now incurring a
problem, verify any recent changes to the system to ensure that these changes are not causing the
problem. Try the following:
1. If the system configuration has changed: Remove the change to see if it affected the loader.
2. If an operating system corrective patch has been installed: Remove it to see if it affected the
loader.
3. If a SCSI device has been added: Check for SCSI ID conflicts.
4. If a SCSI device has been added: Check if the SCSI termination has been properly set.
