Features
2 Installation CAUTION: Back up your system data before changing or installing hardware. Follow the steps in this chapter to install the host bus adapter.
WARNING! When installing the adapter in a server in a rack, to reduce the risk of personal injury or damage to the equipment, adequately stabilize the rack before extending a component outside the rack. Extend only one component at a time. A rack may become unstable if more than one component is extended. The installation procedure involves the following steps: 1. Planning the installation (see page 14) 2. Preparing the server (see page 16) 3. Installing the adapter hardware (see page 17) 4.
The last device in the bus — that farthest from the adapter — must be properly terminated for each SCSI bus. When planning device termination, keep the following in mind: • Use an LVD terminator if you are only using LVD devices. Although you can use a Single-Ended terminator, all devices will be limited to Ultra SCSI speeds and cable lengths. Single-Ended devices require a Single-Ended terminator.
b. Use a small, flat screwdriver to remove the four stand-offs on the external connectors, as shown in Figure 3. 11315 Figure 3 Removing the stand-offs c. Remove the bracket and replace it with the low-profile bracket. Verify that the new bracket is oriented correctly, as shown in Figure 4. 11316 Figure 4 Card with low-profile bracket d. Replace the four stand-offs to secure the bracket to the board. e.
Installing the adapter hardware CAUTION: Electrostatic discharge can damage electronic components. Be sure you are properly grounded before beginning this procedure. For more information, see "Appendix: Electrostatic discharge" on page 53. To install the host bus adapter hardware: 1. Open the server case. WARNING! To reduce the risk of personal injury from hot surfaces, allow the drives and the internal system components to cool before touching them. 2.
4. Power up the server and peripherals. The HP U320e SCSI Host Bus Adapter comes pre-configured to operate properly in a variety of common setups. However, some systems may benefit by tuning the adapter for a specific application. See Chapter 4 on page 25 for information on changing host adapter settings. Installing drivers After installing the HP StorageWorks U320e SCSI Host Bus Adapter, you must configure your system to recognize and use it by installing drivers for your operating system.
2. Unzip the driver package and view the readme.txt file for release notes and installation instructions. HP provides patches for the AH627A driver in the Linux 2.4 and 2.6 kernels to allow the driver to operate on the HP StorageWorks U320e SCSI Host Bus Adapter. Updating firmware The HP StorageWorks U320e SCSI Host Bus Adapter ships with the latest firmware installed. If you are installing a new adapter, you do not need to update the firmware.
Installation
3 SCSI Domain Validation utility (Windows only) The SCSI Domain Validation utility tests the physical connection between host adapter and devices to ensure that the desired data transfer speeds can be achieved. Domain Validation eliminates the guesswork of determining transfer rates and is a handy tool for configuring SCSI busses.
5. Follow the directions in the installer to finish the installation. Running the Domain Validation utility To run the ATTO SCSI Domain Validation tool: 1. Launch the tool. 2. Select the adapter Channel of the SCSI bus, as shown in Figure 6. Figure 6 Domain Validation Utility 3. Select the tests to be run. 4. In Fallback Scheme, select the negotiation parameters. The SDV test starts with the highest values and if a problem is detected, tests with the next lower set of values. 5.
The SCSI Domain Validation help text provides useful information about setting up the tests. Review the help text for a more detailed explanation of the tool.

4 Configuration tool The HP StorageWorks U320e SCSI Host Bus Adapter ships with the latest firmware installed and configuration set to work in most installations. Use the ATTO Configuration Tool to see information about installed adapters, drivers and devices, and change NVRAM settings on the adapter. This program executes under: • Windows® XP/2000/Server 2003 • Linux® 2.4 and 2.
Using the Configuration Tool NOTE: The HP StorageWorks U320e SCSI Host Bus Adapter is designed to operate properly using factory settings. Entering invalid or incorrect settings when using an NVRAM configuration utility, such as the ATTO Configuration Tool, may cause your host adapter to function incorrectly. CAUTION: Back up system data before installing or changing hardware configurations. To start the Configuration Tool: 1. Locate the application icon in the folder you created during installation. 2.
to the adapter and channel selected. See "NVRAM settings" on page 27 for information about the NVRAM settings. PCI information is displayed in the PCI Info tab. The current status of the Configuration Tool is represented in the Status window at the bottom of the display screen. The About panel, selected from the About menu item in the Help tab, is an informational screen only. The panel displays a list of components installed for the ATTO Configuration Tool and the tool's version number.
Fallback Sync Rate (MB/s) Choices: 40/20, 20/10, and 10/5 Default: 40/20 Specifies the maximum synchronous transfer rate to be negotiated when the adapter detects a Single-Ended SCSI bus. The bus is Single-Ended when Ultra SCSI devices are connected to the bus. Bus Reset Delay (sec) Read only; no choices Default: 3 The time delay between the reset of the SCSI bus and the scanning of the SCSI bus. This is a read-only parameter.
Sync Rate (MB/s) Choices: Sync DT IU (320, 160), Sync DT (160, 80, 40), Sync ST WIDE (80, 40, 20, 10), Sync ST Narrow (40, 20, 10, 5) Default: Sync DT IU 320. If synchronous transfers are enabled, the sync rate specifies the maximum rate at which host bus adapter negotiates with the selected target ID. Set the rate to the maximum value supported by the host adapter. If excessive SCSI errors occur, you have long cables, or there are many devices on the bus, you might want to reduce the Sync Rate value.

5 Troubleshooting This chapter describes troubleshooting techniques that can be used to identify and resolve issues associated with the HP StorageWorks U320e SCSI Host Bus Adapter. Some of these techniques may seem simplistic or overly obvious, but these are the ones that are commonly overlooked and can take several hours of frustration to find. It is important to only try one technique at a time.
Windows installation troubleshooting When working properly, the ATTO Technology Banner should appear shortly after booting the computer, as shown in Figure 7. Figure 7 ATTO Technology Banner The adapter will be listed as ATTO ExpressPCI UL5D SCSI Adapter in the Windows Device Manager, as shown in Figure 8.
Symptoms Troubleshooting steps The host adapter is installed in the computer but it does not appear during the system BIOS scan. • Check the adapter installation (see Investigating the adapter installation, page 31). • Verify that the latest version of the computer BIOS is installed. Use caution when updating the computer’s BIOS. A mistake could leave the system in an unusable state. • Remove any non-vital PCI cards from the system to determine if there is a PCI bus conflict.
Symptoms Troubleshooting steps The host adapter is detected during the system's BIOS scan but it is not detected by the operating system. When working properly, the host adapter will be listed in the Windows Device Manager, as shown in Figure 8 on page 32. • The driver may not be properly installed. See "Installing Windows drivers" on page 18 for instructions on installing the operating system driver. • The firmware and driver may not be at compatible revision levels.
Linux installation troubleshooting Table 5 Linux troubleshooting table Symptoms Troubleshooting steps The host adapter driver was loaded properly and everything was working, but the devices do not show up after the computer was rebooted. On some Red Hat Linux distributions, the driver may not automatically load when the system is booted. • To enable driver autoload in Red Hat 4, add the following line to /etc/modprobe.
Symptoms Troubleshooting steps The host adapter is recognized, but it does not detect any of the connected SCSI devices. The command dmesg can be used to see what devices are detected on each SCSI bus. • Check the SCSI devices and cables (see Investigating the SCSI cables and devices, page 31). • Try putting the host adapter in a different PCI slot. • Try updating the firmware on the host adapter as described in Updating firmware. • If all else fails, replace the SCSI host adapter.
Table 7 Messages from Flash tab actions Error message Solution This is not a flash file, or it is corrupt. The flash file is corrupt or the Configuration Tool does not recognize the file as a flash file. Only select flash files from the product CD or downloaded from the HP website. This HBA is not compatible with the selected flash file. ATTO flash files are created based on the type of card flashed. ATTO flash files are only compatible with certain ATTO cards.
Increase transfer size If you are writing to an application that uses a lot of sequential disk I/O to a contiguous area on disk, you should use as large a transfer size as possible to reduce overhead on the system, on the SCSI bus and within disk drives.
