The Diagnostics Menu
Table 6 Diagnostics Menu - Item Name and Description
Item name Description
Capture logs Displays a log that contains information about library and drive
configuration, event log and error log. This log can be saved to a file or
sent via e-mail to technical support.
System test Runs a test of the library hardware.
Cycle test Starts a test where cartridges are moved randomly between magazine
slots and between the drive and the magazines.
Verifying Hardware
1. The library uses one SCSI ID for each SCSI tape drive. Verify that the drive SCSI IDs are set to
unique SCSI IDs that are not used by any other SCSI device on the same bus. Depending on
other devices attached to the same SCSI bus and their SCSI IDs, you may need to change the
SCSI ID of the tape drive(s) before you can use the library.
2. Verify that the system recognizes the tape drives during the boot process.
3. Verify that the SCSI host adapter recognizes the tape drives during its initialization.
4. Verify that the status on the library’s front panel interface is OK.
5. Verify that the power cable is inserted correctly.
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 library is 30cm. 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.
Software Checking
1. Verify that the operating system does not report a problem during the boot.
2. Verify that the driver for the SCSI host adapter is present and loaded properly.
3. Verify that the correct Drivers have been installed properly – if applicable.
4. Verify that the Backup software does not report any error messages when loading.
5. If any problem occurs, reinstall the Backup Application Software and check that both the library
and the tape drive are recognized.
Verifying Recent Changes
If the library has been installed previously and operated 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 library.
2. If an operating system corrective patch has been installed: Remove it to see if it affected the library.
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.
