HP 2100 ER manual Recheck for the appearance of the library Scsi devices

	3. If the workstation does not display the SCSI devices under the Fibre
	Channel HBA in the control panel, restart the workstation and then
	recheck for the appearance of the library SCSI devices.
	4. (If DLT) Run the tape diagnostic utility from the NT workstation to
	verify that the library and drives are detected and pass all self-tests.
NOTE	(If DLT) If the tape diagnostic utility has not been installed, install this
	software from the DIAG subdirectory on the User Guide CD-ROM.
	5. Verify SCSI Bus Configuration: Check all appropriate devices for the
	following conditions:
	• Termination: Problems with termination can cause intermittent or
	hard failure. Two connectors are implemented for each SCSI bus,
	supporting middle of bus configurations.
	Terminate the SCSI bus on both ends, and only at the ends of the
	bus. Check each terminator and connector for bent pins.
	• Bus Type: Single-ended devices cannot be combined with
	differential devices on the same bus. Similarly, differential
	terminators cannot be used on the single-ended Fibre Bridge.
	• Device ID: Each device on a SCSI bus must have a unique ID. The
	default SCSI ID of the Fibre Bridge is 7. Make sure that this ID is
	not in use on the bus. Check the library user guide for the default
	SCSI IDs. Verify that other IDs on the bus are not in conflict.
	• Cabling: Check SCSI cables to verify that they are functional, then
	perform the following procedures:
	a. Be sure the maximum cable length on the single-ended SCSI
	cable connected to the Fibre Bridge does not exceed a total of 3
	meters.
	b. Check all cable connections and pins on the connectors. Reseat
	the connections if necessary.
