5 Troubleshooting

This chapter contains solutions for the most common problems you might encounter. If you need additional assistance, please refer to the ATTO Technology website, www.attotech.com, or contact an authorized ATTO Technology representative.

General suggestions

Check each cable connection on every device.

Verify all cables are in proper working condition. Loose or broken cables are often the cause of errors or problems.

Check that Fibre Channel devices are plugged into an AC outlet and are turned on before you add power to your computer.

Mac OS X

Note

The Celerity FC supports Mac OS X versions 10.4.x and later.

1Open the ATTO Configuration Tool from the ATTO Utilities CD or download from the ATTO website. Refer to the ATTO Utilities Installation and Operation Manual for additional information.

2If the adapter does not appear in the Device Listing, make sure it is properly seated in the PCI slot.

a.Remove power from the PC.

b.Remove the case.

c.Check the PCI slot.

d.Replace the case.

e.Apply power.

Note

If the Celerity adapter is properly seated and devices are still not accessible, contact an authorized ATTO representative.

3Verify the driver is loaded.

a.Click on the adapter name in the Device Listing to view the Basic Info screen.

b.If the Driver Information section indicates Unknown: driver not loaded, reinstall the driver. Refer to Updating Hardware Flash, Drivers on page 25.

c.If reinstalling the driver does not fix the problem, contact an authorized ATTO representative.

4Reset the NVRAM for all channels to defaults and reboot. If the problem persists, contact an authorized ATTO representative.

Note

When calling ATTO Technical Support, please have a printout of the IOreg listing and output from the Apple System Profiler available.

Windows Server 2008, 2003, 2000; Vista, XP

If the card has been recently re-flashed, a new Windows driver must be installed. Follow the procedure in Updating Hardware Flash, Drivers on page 25.

All of the external devices connected to the host adapter should be identified. If they do not appear in the Device Manager, the external devices or connection may not be working properly.

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.

Windows 2000/XP/Server 2003/Vista are Plug- n-Play operating systems: be sure your computer’s BIOS is set accordingly.
