Celerity FC host adapter does not appear in ASP

Problem: The Celerity FC host adapter is installed but is not listed in the ASP output.

To troubleshoot this problem, perform the following steps:

1. Ensure that the host adapter is seated properly by powering down the computer and reseating

the host adapter.

2. Verify the host adapter driver installation.

3. Move the host adapter to a different slot.

4. If the problem persists with the host adapter, replace it with a new host adapter.

5. Ensure that the PCIe adapter is installed in a slot configured as x4 or x8.

6. Remove any nonessential PCI cards to determine if there is a PCI bus conflict.

7. Disconnect all Fibre Channel devices from the host adapter and reboot the computer.

• If this corrects the problem, check the Fibre Channel cable, SFPs, or Fibre Channel target

devices as described in “Fibre Channel device is faulty” on page 58.

• If the computer does not boot, install the host adapter in a different computer.

• If the host adapter works in the new computer, update the flash on the host adapter as de-

scribed in the ATTO Celerity 4-Gb and 8-Gb Host Adapter Installation & Operation Manual,

and then move the host adapter back to the original computer.
