• If the application software or operating system does not detect any devices on the HBA:
• Verify that your parallel SCSI host adapter is installed correctly. Refer to the manual that came
with your parallel SCSI host adapter for installation and troubleshooting instructions. Pay par-
ticular attention to any steps describing configuration settings. Make sure that the host adapter
is properly seated in the motherboard slot and the operating system correctly detects the host
adapter. Make sure that the proper device driver is installed for the parallel SCSI host adapter.
• If the Library is detected by the operating system, but not by the application software:
• Refer to the documentation included with your backup application for instructions on how to
verify proper installation. Some backup software packages require an additional module to
communicate with the robotics.
• If the Library is detected by the operating system, but is listed as an unknown or generic device:
• Make sure that the proper device driver, if applicable, is installed for the device. Check your
software provider's website for the latest drivers and patches.
NOTE:
Many backup applications use their own drivers. Before installing a driver, make sure it is not
in conflict with the application software.
If you continue to have problems with a parallel SCSI Library, check the following:
• Ensure that the device is compatible with the parallel SCSI host adapter and backup application
you plan to use. For a list of compatible parallel SCSI host bus adapters and application software,
check with your parallel SCSI host adapter manufacturer, backup application vendor, or the HP
support website at http://www.hp.com/go/ebs.
NOTE:
The host bus adapter should be SCSI-3 LVDS. A single-ended parallel SCSI host bus adapter
severely degrades performance. Also, if any SE devices are on the same parallel SCSI bus, all of
the devices on the bus slow down to SE speed, which severely degrades performance.
The Library is NOT compatible with a standard differential (Diff) or high-voltage differential (HVD)
SCSI bus.
• Verify that your HBA is supported by the host computer and qualified with the Library. Refer to
the EBS matrix at http://www.hp.com/go/ebs for current HBA compatibility information.
• If one of the ports on the device is not connected to another parallel SCSI device, the port must
be terminated. Only the devices physically located at the beginning and end of the parallel SCSI
bus should be terminated. Refer to the manuals supplied with the other devices on the parallel
SCSI bus for information on enabling or disabling termination on those devices.
• To terminate the second parallel SCSI port on the device, locate the terminator in the accessories
package and press it firmly into either of the two parallel SCSI connectors on the back panel.
Secure the terminator by tightening the finger-screws until snug. The supplied terminator is
“dual mode” and works on both Low-Voltage Differential (LVD) and Single Ended (SE) SCSI
buses. Check all parallel SCSI and power connections and confirm that the unit is attached to
a valid SCSI SE or LVDS bus.
