ATTO UL5D Troubleshooting Guide
This document describes troubleshooting techniques that can be used to identify
and resolve issues associated with the ATTO Ultra320 dual channel SCSI host
adapter. 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.
A.) Windows Operating Systems
Æ
The computer will not boot past its Power On Self Test 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.
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.
Æ
The UL5D host adapter is installed in the computer but it does not appear during
the system BIOS scan.
Note: The ATTO Technology banner should appear shortly after booting the
computer.
