ATTO Technology Celerity FC-42XS Troubleshooting Manual

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
