Library Troubleshooting
CAUTION
This library is designed to operate when installed in a rack using the rack
rail kit. Operating the library without installing it in the rails, such as on a
table or rack shelf, could result in library errors. Placing any weight on
top of the library might also cause errors.
8.1
Fibre Channel Connection Problems
Navigate to the
Status> Drive Status
page to check the link connection for your tape drive.
Each tape drives should report its connection Speed, Port Type, Interface Status and Port ID.
If any of the items are missing, go to the
Configuration > Drives
page and verify that Speed and Port
Type are set to Automatic.
If there are still issues:
•
Check the Speed and Port Type setting on the FC switch (if connected to switch) and the host
HBA. In some instances, speed or port type matching between drive and host may not be
compatible. You may need to select the proper speed and port type on both drive and host to
obtain a connection.
•
Disconnect and reconnect the FC cable. Check to see if the cable is damaged. FC cables are
delicate. If the cable has been bent or twisted sharply, it might be broken and must be replaced.
If you are connected to a Loop port:
•
Try selecting Soft for the Loop mode to allow the system to select an available address each time
the tape drive connects to the FC fabric. If your server configuration does not support changing
addresses, try using the Hard Auto-Select option for the Loop mode. This allows the system to
select an available address when it first connects, and then retain that address for future
connections.

Detection Problems after Installing a SAS Drive
Problems encountered after installation are often caused by improper SAS cable connections, application
software configuration errors, or an incorrectly configured operating system. If the application software or
operating system does not communicate with the library after installation, determine the extent of the
detection problem:
•
Does the application software detect the tape drive?
•
Does the application software detect the library?
•
Does the operating system detect the tape drive?
•
Does the operating system detect the library?
•
Does the operating system detect the library, but list it as a generic device? Based on the extent of the
detection problem, check the following:
•
If neither the application software nor operating system detects the tape drive:
•
Verify that all SAS cables are securely connected on both ends. Mini-SAS connectors are
keyed can only be connected one way. If you feel resistance when connecting the cable,
