• Save the changes and restart the server with the Fibre Channel device attached.

3. Watch the LED indicators on the Fibre Channel devices before, during, and after startup.

• Drive LEDs should flash at startup as the Fibre Channel port is scanned.

• If a drive LED remains on when the server freezes, there is a problem with the drive.

ATTO Configuration Tool does not show an online status for a device

Problem: The ATTO Configuration Tool does not show a device status as online.

To troubleshoot this problem, perform the following steps:

1. Check the power and data connections to all devices.

2. Use the ATTO Configuration Tool to identify inactive paths.

• The Celerity FC host adapter and target WWPNs identify the endpoints of the path.

• If you have intermediate devices, such as a Fibre Channel switch, you may need to use the

management software for those devices to find the problem.

3. Use the ATTO Configuration Tool to identify the host adapter channel.

a. In the multipathing window, select the path that you want to identify.

b. Right-click (or press Ctrl+click) the path and select Identify from the menu.

A check mark appears next to the Identify menu item, indicating that the path is being

identified.

The link LED blinks continuously for the host adapter channel associated with the path.

c. After you have identified the Celerity FC host adapter channel, select Identify from the menu

to stop identification.

4. After you have identified the faulty path, verify the cable integrity:

• Check the cable connections.

• Inspect the SFPs for physical damage and replace them, if necessary.

• Inspect the cable ends for dirt or abrasions, which can affect communication.

• Replace the cable.

As you replace components in the path, the ATTO Configuration Tool automatically refreshes the

display to indicate changes.

5. Repeat Step 2 through Step 4 until the device status is Active.

Path disappears from the ATTO Configuration Tool after rebooting the server

Problem: A path disappears after rebooting the server.

This problem can occur if the missing path failed prior to reboot. You must repair the path and then

reboot the server.

ATTO Configuration Tool does not display paths

Problem: The ATTO Configuration Tool does not display paths or the Path tab is unavailable.

This problem occurs when an unsupported Celerity FC host adapter driver or ATTO Configuration

Tool are installed instead of the driver and ATTO Configuration Tool developed specifically for EVA.

To troubleshoot this problem, perform the following steps:
