Procedure 3: Checking SAS Host Connections
Check the host connections for your drive by following the steps below.
If your server is not communicating with the SAS drive, the problem may be with
the SAS cable, the SAS host adapter or the SAS host adapter setup.
1. Check if the tape drive power is on.
2. Verify the SAS cable is connected properly to the server and to the tape drive.
3. Check whether the parameters for the SAS host adapter installation are correct.
4. Verify the SAS host adaptor is supported by the tape drive.
5. Ensure there is a point-to-point connectivity between the server and the tape
6. Check the length of the SAS cable. It can 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 perform this test is the ITDT utility
available on the web at http://www.ibm.com/support/fixcentral. This utility is
especially effective for updating the drive firmware and for performing the Test
Device function. For additional information about using the ITDT utility, see
"Updating firmware" on page 2-6. Perform the following steps:
1. If the ITDT utility is not installed on your system, download the appropriate

compartment) and ensure that there are no gaps in the seam of the cartridge
case (see 1 in Figure 4-4 on page 4-8 and 4 in Figure D-2 on page D-2). If
there are gaps, the leader pin may be dislodged. Go to Appendix D, "Repairing
a Cartridge," on page D-1.
v If it fails, contact your service representative for additional problem
determination.
v If it is successful, discard the cartridge that originally failed.
1. If a damaged or mishandled cartridge is the problem, see "Handling
Cartridges" on page 4-7 for proper instructions about handling media. It
is possible that your other cartridges may also be damaged.
2. If your cartridge does not eject properly, contact your service
representative. (IBM service personnel should go to Appendix E,
"Information for Trained Service Personnel," on page E-1.)
