Complete these steps:
1.
If the ITDT utility is not installed on your system, download the appropriate operating
system version from the web into a directory or folder of your choice.
2.
When installation is complete, run the SCAN option to determine whether your system
can detect all of the LTO tape drive devices (including any libraries or autoloaders that
might be on the bus).
3.
Select the drive that is to be tested or to have firmware that is downloaded.
4.
For testing, select the Test Device option.
NOTE: This option completes a series of LOADS, UNLOADS, and WRITE/READ operations. Both
tape drive control commands and data are sent to the device over the interface bus.
5.
If allowed to complete, the test runs for at least 30 minutes.
At any time an ABORT is entered to end the device test early if it is determined that
interface communications are satisfactorily achieved.
Resolving Problems Reported by the Server
The procedure for fixing interface bus errors varies, depending on whether the error is
consistent or intermittent, and on your configuration. These sections describe how to fix an
error.
Fixing SAS Communication Problems
1.
Check whether the tape drive power is On.
2.
Verify that the SAS cable is connected to the host server and to the tape drive.
3.
Verify the host server's SAS HBA is using the latest drivers.
4.
Make sure all the settings and parameters for the SAS HBA are configured properly.
Refer to the HBA manufacturer user guide for additional information.
5.
Replace the SAS cable if shows any signs of damage.
Fixing FC Communication Problems
1.
Check whether the tape drive power is On.
2.
Verify that the FC cable is connected to the host server and to the tape drive.
3.
If using a fibre channel switch, make sure both host server and tape drives are
connected and the ports have a link. Make sure proper FC zoning is configured for the
host server and tape drive. Additional troubleshooting can be found from the
manufacture of the fibre channel switch user guide.
4.
Verify the host server's FC HBA is using the latest drivers.
5.
Make sure all the settings and parameters for the FC HBA are configured properly.
Refer to the HBA manufacturer user guide for additional information.
6.
Replace the FC cable or Fibre Channel SFP on the switch if they shows any signs of
damage.
