Troubleshooting
Windows NT
❖ 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 NT.
If the devices connected to ATTO ExpressPCI
host adapter are not accessible:
1Open the SCSI Adapters utility in the Control
Panel under Settings.
2 Verify the ATTO ExpressPCI host adapter
64-bit PCI SCSI host adapter appears under
the Devices List.
3 If it does not appear in the Device List, verify
that the adapter is seated properly in the PCI
slot (remove power from the PC, remove its
case, check the PCI slot, replace the case,
apply power).
4 If it has been identified, click on the Drivers
Tab to see if the ATTO ExpressPCI host
adapter driver has been started. It will say
Started in the right hand column of the
window. If the ATTO ExpressPCI host
adapter driver appears but is not started,
check on the device status. In the Control
Panel click on Devices and scroll down to
express2. Click Startup button. Startup type
should be Boot. Click on Hardware profiles,
status should be Enabled.
5If ExpressPCI does not appear in the Device
List, try reloading the driver software as
described in Chapter 3.2 of this manual.
6 If it is started, go back to the Devices tab of
the SCSI adapters utility window and double
click on the ATTO ExpressPCI host adapter
description, and then on the bus it is
assigned to. All of the external devices
connected in the loop should be identified.
If they do not appear in the Device List, the
external devices or connection are not
working properly.
❖ If the card has been recently re-flashed with
new firmware, the new NT driver must be
installed.
❖ 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 suggestions do not solve the
problem, re-flash the host adapter and re-
install the Windows NT driver.
Macintosh
❖ Power up SCSI drives before booting up
your machine. If the Macintosh host is
powered up before the drives, the drives
may not automatically mount (depending
on when the drives were powered on).
❖ Re-flash the card using the updater program
(See Chapter 3.2). Select the unconditional
flash option when attempting to re-flash
the host adapter.
