HP StoreEver MSL6480 Tape Library User and Service Guide

5 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.
Fibre Channel connection problems
Full height tape drives can only be installed in the very top, very bottom, or middle pair of half-height
drive bays. A full-height drive cannot be seated in other locations and will not operate. If the drive
will not seat completely, verify that it is located in one of the three full-height drive locations.
Use the Status > Drive Status screen to check the link connection for your tape drive.
If the screen shows Logged Out:
• Check that the Fibre speed is set to Automatic or that the correct fibre speed is selected. If you
are unsure of the speed of the HBA or switch that the drive is connected to, try Automatic.
• Check that the correct port type, fabric or loop, is selected. Loop requires additional
configuration. If you are unsure of the correct port type, try Automatic.
If the screen shows No Link, the Speed Status is – and the Link LED on the back of the drive is off:
• The speed is probably set incorrectly. Try setting the speed to Automatic.
• If there are still issues, change the port type to Auto Detect.
If the screen shows No Light:
• The cable is not plugged in correctly. Check that it is connected correctly to Port A of the tape
drive.
• 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 the screen shows ALPA Conflict:
• There might be a conflict with the ALPA address on Loop ports. Select 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:
