2. If your cartridge does not eject properly, contact your service representative.

Procedure 2: Checking SAS host connections

Use this information to check 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

Use this information to verify 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.
