3 Troubleshooting See the Troubleshooting chapter in the relevant user and service guide for detailed troubleshooting information and error codes. "Using the Status screen" is specific to troubleshooting a FC connection. NOTE: HP Library & Tape Tools is provided free with your tape library and is the recommended diagnostics tool for your tape library. It provides an intuitive graphical user interface with integrated context-sensitive help. It can also be downloaded free of charge from www.hp.com/support/TapeTools. Using the Status screen Use the Status screen to check the link connection for your tape drive. If the screen shows Logged Out • Check that you have selected the correct fibre speed. If unsure of the speed, try the Auto Detect option. • Check that you have selected the correct port type, fabric or loop. Loop requires additional configuration. 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 (on the RMI interface) or Auto Detect (on the OCP) • 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 may be broken and you will need to replace it If the screen shows ALPA Conflict • There may 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. 10 Troubleshooting
