Mac OS X Fibre Channel connectivity to the HP StorageWorks Enterprise Virtual Array storage system configuration guide (5697-0025, August 2009)

2. Move the host adapter to a different slot.
If the problem persists with the host adapter, replace it with a new host adapter.
3. Ensure that the PCIe adapter is installed in a slot configured as x4 or x8.
4. Zap the PRAM (Command+Option+P+R) at boot. Allow it to chime three times.
5. 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, contact HP and report this as a possible inter-
operability issue between the host adapter and the computer.
Mac OS X stops and displays a flashing question mark
Problem: With the Celerity FC host adapter installed, the operating system stops and displays a
flashing question mark, indicating that the hardware cannot find an operating system from which to
boot.
To troubleshoot this problem, perform the following steps:
1. Boot the computer from a CD or some other source.
2. Check the System Preferences field to ensure that the startup disk is defined as Startup disks.
NOTE:
The Celerity FC host adapter does not support booting from an external Fibre Channel drive.
Server freezes or hangs
Problem: The server freezes or hangs.
To troubleshoot this problem, disconnect all Fibre Channel devices, and then reboot the computer.
• If the server continues to hang:
1. Remove the nonessential PCI cards to determine if there is a PCI bus conflict.
2. Remove the host adapter and test it in a different model computer.
3. If the problem persists with the host adapter, replace it with a new host adapter.
• If the server no longer hangs:
1. Verify the cable integrity:
• Check the cable connections.
• Inspect the SFPs for physical damage.
• Replace the SFPs if necessary.
• Inspect the cable ends for dirt or abrasions, which can affect communication.
2. Boot the server and use the ATTO Connection Tool to:
• Set the connection mode to PTP.
• Set the data rate to the speed of your target device.
By default, the Celerity FC host adapter autonegotiates these parameters.
