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.
