FIBRE CHANNEL CONNECTION PROBLEMS
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, select 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, select
Automatic.
If the screen shows No Link, the Speed Status displays the ‘-’ character, 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.
