Chapter 5. Troubleshooting
The following four types of installation problems might cause your DS4000 FC
4Gbps PCI-X Adapter to function incorrectly:
v Hardware problems
v Software problems
v System configuration problems
v Fibre Channel problems
If you are having problems, use the following information to help you determine the
cause of the problem and the action to take.
Note: Additional troubleshooting and debugging procedures are available in the
IBM System Storage DS4000 Hardware Maintenance Manual and IBM
System Storage DS4000 Problem Determination Guide at
http://www-1.ibm.com/servers/storage/support/disk/.
Hardware problems
To determine if your installation problem is caused by the hardware, perform the
following tasks:
v Verify that all cables are attached securely to the correct connectors. Be sure
that one end of the LC-LC Fibre Channel cable is attached to the optical
interface connector (located at J1 on the adapter) and that the other end is
connected to the Fibre Channel device.
v Verify that the FC 4Gbps PCI-X Adapter is installed correctly and is fully seated
in the expansion slot. Check for interference due to nonstandard PCI connectors.
v Verify that the Fast!UTIL data-rate setting is correct. The Fast!UTIL data-rate
setting must match the speed of the device to which you are connected. See
“Host bus adapter settings” on page 24.
v Verify that all peripheral devices are turned on. See “Fibre Channel problems” on
page 32 for information about displaying attached Fibre Channel devices.
v Verify that the adapter is ServerProven
™
for the server model in which the
adapter is installed. Verify that the latest BIOS is installed in the server.
Software problems
To determine if your installation problem is caused by the software, perform the
following tasks:
v Verify that the correct device driver is installed.
v Verify that your adapter is at the correct BIOS version.
v Verify that you have the correct adapter NVRAM settings for your Storage Area
Network (SAN) and operating system.
System configuration problems
To determine if your installation problem is caused by the system configuration,
check your server to ensure that it is configured properly. For more information, see
“Host bus adapter settings” on page 24.
