Technical data

2. Use the ATT O 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 p ath that you want to identify.
b. Right-click (or Ctrl+click) the path and select Identify from the menu.
A check mark appears next to the Identif y 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 physic al 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 re pair the path and then
reboot the server.
ATTO Configuration Tool does not d isplay 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 prob lem, perform the following steps:
1. Use the Terminal command Kextstat | grep ATTO to verify the host adapter driver version
and
ATTO Configura tion Tool version.
See
Table 3 for the supported versions.
2. Reinstall the host adapter driver or ATTO Configuration Tool, if necessary.
Escalation checklist
If you
cannot resolve a problem using the information in this guide, collect the following information
befor
e
escalating the issue to technical support personnel:
• Computer model
• Operating system
• OS pa
tch level
• PCI or PC I e slot number and type (for example, x4, x8)
• Celerity FC host adapter driver version (available from the ATTO Configura tion Tool)
• List
of all devices attached to the host adapter
• Did this configuration ever work?
