Procedure 2: Checking SAS host connections
If your server is not communicating with the SAS drive, the problem might be the
SAS cable, the SAS host adapter, or the SAS host adapter setup.
To check the compatibility of your System x hardware and options, go to
http://www-03.ibm.com/systems/info/x86servers/serverproven/compat/us/
indexsp.html.
To check the host connections for your drive, complete the following steps:
1. Make sure that the tape drive power is on.
2. Make sure that the SAS cable is fully-seated in the server and in the tape drive.
3. Make sure that the parameters for the SAS host adapter installation are correct.
4. Make sure that the SAS host adapter is supported by the tape drive.
5. Make sure that there is a point-to-point connectivity between the server and the
6. Check the length of the SAS cable. It must not exceed 5.5 m (18 ft).
Procedure 3: Verifying host interface communication
The Wrap diagnostic tests the communication function at the device interface.
However, to thoroughly verify host-to-device communications, initiate activity over
the SAS interface bus from the host to the drive and back. A utility to perform this
test is the IBM TotalStorage Tape Diagnostic Tool (ITDT). ITDT is available on the
IBM website at http://www.ibm.com/storage/lto.
The ITDT is effective for updating the drive firmware and for performing the Test
Device function. For additional information about using the ITDT, see "Updating
firmware" on page 16. To use the ITDT to execute the Test Device function,
complete the following steps:

compartment) and make sure that there are no gaps in the seam of the
cartridge case (see Figure 16 on page 66). If there are gaps, the leader pin might
be dislodged. See Appendix D, "Repairing a cartridge," on page 65.
v If the new cartridge loads or unloads properly, discard the cartridge that
originally failed.
v If the new cartridge does not load or unload properly, contact your IBM
technical-support representative for additional problem determination.
1. If a damaged or mishandled cartridge is the problem, see "Handling
cartridges" on page 44 for proper instructions about handling media. It
is possible that your other cartridges might 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 73.)

daisy-chain of devices).
