CAUTION:
rails. Operating the library without installing it in the rails, such as on a table or rack shelf, could
result in device errors. Placing any weight on top of the library might also cause errors.
CAUTION:

Fibre Channel connection problems

The MSL4048 library will not operate with a full-height tape drive installed in the middle two
half-height drive bays. Verify that the full-height tape drive is installed in a supported position. A
full-height drive can only be installed in either the upper or lower two half-height drive bays.
Use the 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 (on the RMI) or Auto Detect (on the OCP),
or that the correct fibre speed is selected. If you are unsure of the speed of the HBA or switch
that the library is connected to, try Automatic (on the RMI) or Auto Detect (on the OCP).
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 (on the RMI) or Auto
Detect (on the OCP).
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 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 or drive 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?
