IBM DS4000 FC manual Troubleshooting, Hardware problems, Software problems

Chapter 5. Troubleshooting

The following four types of installation problems might cause your DS4000 FC 4Gbps PCI-X Adapter to function incorrectly:

vHardware problems

vSoftware problems

vSystem configuration problems

vFibre 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:

vVerify 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.

vVerify 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.

vVerify 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.

vVerify that all peripheral devices are turned on. See “Fibre Channel problems” on page 32 for information about displaying attached Fibre Channel devices.

vVerify 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:

vVerify that the correct device driver is installed.

vVerify that your adapter is at the correct BIOS version.

vVerify 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.
