ATTO UL4S/D and UL5D Troubleshooting Guide for Mac OSX

This document describes troubleshooting techniques that can be used to identify

and resolve issues associated with the ATTO Ultra320 SCSI host adapters.

Some of these techniques may seem simplistic or overly obvious, but these are

the ones that are commonly overlooked and can take several hours of frustration

to find. It is important to only try one technique at a time. While changing

multiple variables may seem to be a time saver, it usually complicates the

troubleshooting process.

The computer will not boot when the host adapter is installed.

The host adapter may be improperly seated. Power down the computer and

reseat the host adapter.

Try putting the host adapter in a different PCI slot.

Make sure that the adapter, if PCIe, is installed in a slot configured as x4 or x8.

Zap the PRAM (command+option+P+R) at boot. Allow to chime 3 times.

Disconnect any SCSI devices from the host adapter and reboot the computer. If

this resolves the issue, investigate the SCSI cables or SCSI target devices as

described in the section below.

If the computer still does not boot, try installing the host adapter in a different

computer. If the host adapter works in the new computer, report this as a

possible interoperability issue between the host adapter and the computer. If the

problem follows the host adapter, replace it with a new adapter.

Verify that the latest version of the computer BIOS is installed. Use caution when

updating the computer's BIOS. A mistake could leave the system in an unusable

state.

With the ATTO host adapter installed my system stops and displays a flashing

question mark.

This is an indication that the MAC is not able to find an OS to boot from.

Use a CD or some other source to boot from and make sure the startup disk is

correctly defined in "System Preferences" "Startup disks".

Check cabling. Make sure cables are secure. Swap out with new cable if

possible.

Check termination.

The U320 SCSI host adapter is installed in the computer but it does not appear in

the System Profiler.

The host adapter may be improperly seated. Power down the computer and

reseat the host adapter.

Check for the correct installation of the driver.

Try putting the host adapter in a different slot.

Make sure that the adapter, if PCIe, is installed in a slot configured as x4 or x8.
