ATTO Celerity FC Troubleshooting Guide for Windows
This document describes troubleshooting techniques that can be used to identify
and resolve issues associated with the ATTO Celerity Fibre Channel 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 Fibre devices from the host adapter and reboot the computer. If
this resolves the issue, investigate the Fibre cables, SFP’s or Fibre 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 Celerity 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.

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.
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.
Remove any non-vital PCI cards from the system to determine if there is a PCI
port conflict.
Disconnect any Fibre Channel devices from the host adapter and reboot the
computer. If this resolves the issue, investigate the Fibre cable, SFP and Fibre
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, try updating the flash
on the host adapter as described in the “Installation and Operations” manual.
Then try it again in the original computer.
o If it still fails, report this as a possible interoperability issue between the
host adapter and the computer.
o If the problem follows the host adapter, replace it with a new adapter.
Æ The computer freezes when the ATTO Banner is displayed during the system
BIOS scan.
Disconnect all devices from the Fibre card and reboot the system.
If the system still freezes:
Remove any non-vital PCI cards from the system to determine if there is a PCI
port conflict.
Remove the Celerity host adapter and test it in a different computer (not the
same model). If the card works properly, enter the ATTO CelerityFC Utility during
the system BIOS scan by hitting Control-F when prompted. Enter the host
adapter configuration menu and disable the BIOS (note: this will need to be done
for each channel). There may be a BIOS conflict between the ATTO host adapter
and the original computer. Place the host adapter back into the original machine
and reboot.
If this resolves the issue, report this as a BIOS conflict. Note that you can
continue to operate. Disabling the BIOS will only prevent the computer
from booting from an external drive connected to the host adapter.
If the computer still hangs, replace the host adapter with a new one.
If the system no longer freezes after disconnecting the Fibre devices:
Check the Fibre devices to see what type of connection mode and data rate they
are set to. Some devices use “auto” for these settings. Manually setting the
speed (1gig, 2gig, 4gig) may allow for proper negotiation between the devices.
You may also want to force these settings on the card. This can be done by
using the ATTO Configuration Tool or entering into the ATTO CelerityFC Utility
(CTRL-F).

Check cable integrity. Check the cables for solid connections. Make sure the
cables snap securely into place. Inspect cable for kinks or cuts. Be careful not to
touch the ends of the cable. Finger prints can cause malfunction in
communication.
Verify the SFP is not damaged and rated for the Data Rate trying to be achieved.
Also, try reseating the SFP. If this does not work, try replacing the SFP with a
new one.
If multiple Fibre Devices are being attached (switch, multiple Drive Arrays) try
connecting one device at a time, adding devices until the problem occurs. This
will help pinpoint the device or cable causing the problem.
Watch the LED indicators on the Fibre card. They should show when you have a
proper link and the connection speed you have negotiated with the device after
startup. Drive lights should also flash at startup as the Fibre port is scanned.
This may give a clue as to the root cause of the issue.
Æ The system’s BIOS scan recognizes the Celerity FC host adapter, but does not
detect
any of the connected SCSI devices.
Note: The ATTO Technology banner should appear shortly after rebooting the
computer. If the host adapter’s BIOS is set to “enabled” or “scan only”, the
connected devices, WWN and negotiated transfer rate for each of the Fibre ports
will also be displayed.
The Celerity host adapter BIOS may have been set to disabled (factory default:
BIOS enabled). Set it back to Enabled (if you need to boot from an external
device connected to the host adapter) or Scan Only.
Verify the Fibre devices are powered on.
Check cable integrity. Check the cables for solid connections. Make sure they
snap into place. Inspect cable for kinks or cuts.
Verify the SFP is not damaged and rated for the Data Rate trying to be achieved.
Also, try reseating the SFP. If this does not work, try replacing the SFP with a
new one.
If multiple Fibre Devices are being attached (switch, multiple Drive Arrays) try
connecting one device at a time, adding devices until the problem occurs. This
will help pinpoint the device or cable causing the problem.
Watch the LED indicators on the Fibre card. They should show when you have a
proper link and the connection speed you have negotiated with the device after
startup. Drive lights should also flash at startup as the Fibre port is scanned.
This may give a clue as to the root cause of the issue.
Try putting the host adapter in a different PCI slot.
Try updating the firmware on the host adapter as described in the “Installation
and Operations” manual.
If all else fails, replace the Celerity host adapter.
Æ The computer’s BIOS scan recognizes the Celerity host adapter, but only detects
connected Fibre devices on
one of the ports. The other port reports no devices.
Please note that if all devices attached to the Fibre card are reported on one channel

Page 4
although connected with two links to the device, this is most likely a MPIO or
Multipathing issue. Please contact Technical Support for further a resolution.
Swap the devices, cables and SFP from the Fibre port that appears to be
working with the one having issues. If the issue follows the Fibre port, verify the
NVRAM settings are the same for both channels (connection mode and data
rate). If this does not resolve the problem, replace the Fibre card.
If the issue follows the attached Fibre devices, troubleshoot the attached
devices:
Verify the Fibre devices are powered on.
Check cable integrity. Check the cables for solid connections. Make sure they
snap into place. Inspect cable for kinks or cuts.
Verify the SFP is not damaged and rated for the Data Rate trying to be achieved.
Also, try reseating the SFP. If this does not work, try replacing the SFP with a
new one.
If multiple Fibre Devices are being attached (switch, multiple Drive Arrays) try
connecting one device at a time, adding devices until the problem occurs. This
will help pinpoint the device or cable causing the problem.
Watch the LED indicators on the Fibre card. They should show when you have a
proper link and the connection speed you have negotiated with the device after
startup. Drive lights should also flash at startup as the Fibre port is scanned.
This may give a clue as to the root cause of the issue.
Æ The Celerity host adapter is detected during the system’s BIOS scan but it is not
detected by the operating system.
Note: When working properly, the Celerity host adapter will show up in the
device manager.
The host adapter driver may not be properly installed. Please refer to the host
adapter Installation and Operations manual for instructions on installing your OS
driver.

The firmware and driver may not be at compatible revision levels. The drivers are
updated more frequently than the firmware, therefore the revision levels are
seldom the same. There may be an occasion where the latest driver also
requires a firmware update. Verify from the web site that the latest firmware and
driver version are being used. The firmware version can be viewed when the
host adapter is detected during the computer’s BIOS scan. The driver version
can be verified from within the Device Manager.
Æ The Celerity host adapter is detected by the operating system, it detects some of
the connected devices on some or all Fibre ports, but
does not detect all of the
connected devices.
Verify the Fibre devices are all powered on.
Check cable integrity. Check the cables for solid connections. Make sure they
snap into place. Inspect cable for kinks or cuts.
Verify the SFP is not damaged and rated for the Data Rate trying to be achieved.
Also, try reseating the SFP. If this does not work, try replacing the SFP with a
new one.
Try connecting one device at a time, adding devices until the problem occurs.
This will help pinpoint the device or cable causing the problem.
Watch the LED indicators on the Fibre card. They should show when you have a
proper link and the connection speed you have negotiated with the device after
startup. Drive lights should also flash at startup as the Fibre port is scanned.
This may give a clue as to the root cause of the issue.
Æ Errors are reported while trying to flash new firmware onto the Celerity host
adapter.
The ATTO Configuration Tool performs validations on the structure of the file. If
it does not pass these validations, the file is rejected. The image file may be
corrupted. Try downloading the image file from the support section of the
website again. If you continue to have problems, contact our Technical Support
Department.
Æ The Celerity host adapter fails its Power On Self Test/Post.
The BIOS driver will perform several checks to verify that the host adapter is
functioning. If the BIOS driver determines that the adapter has non-functioning
hardware it will not complete the initialization of the OS driver. If the BIOS driver
determines that the FW on the adapter is not functioning, then it will complete the
initialization in degraded mode. Under Windows, degraded mode will not
perform I/O but it will allow the end user to flash the adapter with working FW.
The POST failure will be recorded in the Windows Event Log. Try to re-flash the

Page 6
firmware using the Configuration Tool in Windows. If the problem persists,
replace the host adapter.
Æ The software application being used to communicate with the attached Fibre
devices reports Parity or communication errors.
Check your cables. There could be a kink or a cut in the cable. Also, make sure
the ends of the fibre cables are clean. Dirt, such as fingerprints, can obstruct the
fibre link and cause communication problems.
Check the Fibre devices to see what type of connection mode and data rate they
are set to. Some devices use “auto” for these settings. Manually setting the
speed (1gig, 2gig, 4gig) may allow for better communication between the
devices. You may also want to force these settings on the card. This can be done
by using the ATTO Configuration Tool or entering into the ATTO CelerityFC
Utility.
If the issue is not resolved, enable the Event logs as described below and
contact ATTO Technical Support.
Æ Errors are reported while using the ATTO Configuration Tool.
Note: Sometimes when using the ATTO Configuration Tool, an error message
describing an unexpected event or incorrect information discovered by the
application will be displayed.
Use the help text presented with the error message to correct the issue.
The following conditions cause a warning or error message to be posted in the
"Status" area of the configuration utility. These messages will be shown in red.
o An error occurred loading NVRAM data - The first time a host adapter
channel is highlighted, the application makes an attempt to read NVRAM
from the card. If the size of the NVRAM buffer does not match the expected
size, or if the NVRAM buffer couldn’t be retrieved at all, this message is
displayed.
o Warning: NVRAM could not be read, defaults returned - This message occurs
as a result of corrupt NVRAM. When the driver accesses the NVRAM, a
continuity check is performed on the NVRAM to ensure the returned data is
valid. If this check fails, the driver has no other alternative than to return a
known NVRAM data buffer that represents card defaults. When this situation
occurs the defaults are presented via the graphical user interface and the
user is informed that the values shown are defaults. These defaults must be
committed in order to correct the state of the NVRAM.
o An error occurred updating the NVRAM - This message occurs during a
committal of NVRAM to the card. If the driver is unable to put the new
settings on the card, this message is displayed to the user and no changes
are made to the card.
o This is not a flash file, or it is corrupt – Checks are performed to assure the
proper file has been selected for flashing to the specific model of host
adapter.
