3.
Inspect the rear of the cartridge (the part that you load first into the tape load
compartment).
Ensure that there are no gaps in the seam of the cartridge case. If there are gaps, the
leader pin might be dislodged. Go to
“Repositioning or Reattaching a Leader Pin” on
4.
Try loading or unloading another tape cartridge.
•
If it fails, contact your service representative for problem determination.
•
If it is successful, discard the cartridge that originally failed.
Addition notes:
•
If a damaged or mishandled cartridge is the problem, see
for instructions about handling the media. It is possible that your other
cartridges might also be damaged.
•
If your cartridge does not eject properly, contact your service representative.
Procedure 3: Checking Host Connections
If your server is not communicating with the drive, the problem might be with the cable, host
adapter, or host adapter setup. Check the host connections for your drive by following these
steps.
1.
Verify the SAS or Fibre Channel host adapter is supported by the tape drive.
2.
Check whether the LTO tape drive power is On.
For Fibre Channel, if the tape drive is attached to a fibre switch, make sure the switch
is powered on.
3.
Verify that the cable is connected properly to the server and to the tape drive.
For SAS drives, the interface is a mini-SAS SFF-8088. For FC drives, the interface is an
LC multi-mode Fibre Optic.
4.
If using a Fibre Channel switch, make sure that the host server and tape drive have an
FC link on the fibre ports of the switch. Also, make sure the FC switch is configured
correctly to include zoning for both the host server and tape drive.
5.
Make sure the Host server has the proper HBA drivers installed and parameters are
properly configured.
6.
Ensure that there is a point-to-point connectivity between the server and the tape drive.
SAS connectivity does not support multiple drive connections (daisy-chaining of
devices).
7.
Check the length of the SAS or Fibre Channel cable does not exceed 5.5m (18 ft.).
Procedure 4: Verifying Host Interface Communications
The Wrap Diagnostic tests the communication function at the device interface. However, to
thoroughly verify host-to-device communications, it is highly recommended to exercise activity
over the SAS interface bus from the host to the drive and back. A recommended utility to
complete this test is the ITDT utility available on the web at the Overland-Tandberg website.
