Chapter 5 Troubleshooting 109
Chapter 5
Terminate the SCSI bus on both ends, and only at the ends of the bus. By
default, the IM provides internal termination at the IM end of each SCSI
bus. Check each terminator and connector for bent pins.
— Bus Type: The IM can contain any combination of two types of Fibre
Channel interface cards. The card model number A4674A has
hardware for LVDX SCSI buses. The card model number A4673A has
hardware for HVDS SCSI buses. Single-ended (SE) SCSI is supported
by connecting to a LVDS card, but the bus data transfer performance
will be poor.
Note Do not connect a SE SCSI drive into a HVDS card.
— Device ID: Each device on a SCSI bus must have a unique ID. The
default SCSI ID of the IM 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. Be sure
the maximum cable length on the differential cable connected to the IM
does not exceed a total of 25 meters. Make sure that the SCSI cables
are qualified for operation at the intended data rate. Check all cable
connections and pins on the connectors. Reseat the connections if
necessary.
7. Verify SCSI bus operation: Use the Telnet connection between the
Windows NT host and the IM. See Chapter 3 for default settings and for
steps to initiate the following procedures:
—Verify device locations (seeVerify SCSI Bus Configuration on
page 103).
8. Verify IM configurations: Configuration changes may result in an invalid
configuration. Try the default IM configurations settings, as they have been
chosen to work in most cases.
If you are in doubt about the configuration, refer to Chapter 3. If this
procedure fails, contact an HP service representative.
9. Verify devices: If the previous diagnostic procedures have not resulted in a
functional connection between the host computer and each device, use the
following steps:
— Connect the library to a SCSI HBA on the host and restart the host.
Verify functionality with the SCSI connection.
