5 Troubleshooting
This chapter contains solutions for the most common problems you might encounter. If you need
additional assistance, please refer to the ATTO Technology web site (www.attotech.com) or contact an
ATTO Technology authorized representative.
General suggestions
❖ Check each cable connection on every
device. Verify all cables are in proper
working condition. Loose or broken cables
are often the cause of errors or problems.
❖ Check that your SCSI devices are plugged
into an AC outlet and are turned on before
you add power to your computer.
❖ Verity that all devices and busses are
properly terminated. See Chapter 3.1 for
more information.
❖ Verify that all devices attached to the ATTO
ExpressPCI SCSI adapter have unique
SCSI IDs. The ATTO ExpressPCI SCSI
adapter has a default SCSI ID of 7.
❖ If the same device shows up at several
different SCSI IDs, either its SCSI ID is set
the same as the ATTO ExpressPCI SCSI
ID, or the cable is defective.
❖ If a device doesn’t appear and cables and
termination are set properly, try
lengthening the SCSI Reset Delay using
the ExpressPCI Utilities found on the CD
that came with your host adapter.
❖ PC users should make sure that SCSI
adapter firmware and Windows drivers are
at the same revision level. Unless indicated
otherwise, the latest drivers and firmware
can be downloaded from the ATTO
Technology website (www.attotech.com)
Windows 2000/XP
❖ If using an Intel-based PC, SCSI drives
should be booted up before the host
computer. If the PC is powered up before
the drives, the drives may not be visible to
Windows 2000/XP.
If the devices connected to the ATTO
ExpressPCI host adapter are not accessible:
1 Right-click My Computer and select
Properties.
2 Select the Hardware tab and select Device
Manager.
3 If the ATTO ExpressPCI host adapter does
not appear under the SCSI and RAID
controllers, shut down and make sure the
ATTO ExpressPCI host adapter is properly
seated in the PCI slot (remove power from
the PC, remove its case, check the PCI slot,
replace the case, apply power).
4 Reload the driver.
5 If the adapter has been identified but there is
an exclamation point (!) on the listing, right
click on the listing and select Uninstall.
Reboot system and repeat the installation
process. If problems persist, contact your
authorized ATTO Technology
representative.
❖ If the card has been recently re-flashed with
new firmware, the new Windows driver
must be installed. Follow the procedure in
Chapter 3.2.
❖ All of the external devices connected to the
host adapter should be identified. If they do
not appear in the Device Manager, the
external devices or connection may not be
working properly.
❖ For Intel-based PCs, check the computer
CMOS setup and verify that the PCI slots
are configured correctly. Procedures vary
greatly: refer to the manual supplied with
your system or call the computer supplier
for configuration assistance.
❖ If these do not solve the problem, re-flash
the host adapter and re-install the Windows
2000/XP driver.
