Troubleshooting

3.1

Problems After Installation

There are three basic types of installation problems that can cause your QLA22xx board to function incorrectly: hardware problems, system configuration problems, and Fibre Channel problems. The following section provides itemized checklists to help you determine why your QLA22xx board is not functioning.

3.2

Hardware Problem Checklist

Are all of the circuit cards installed securely in the system?

Are all of the cables securely connected to the correct connectors? Be sure that the FC cables that attach from the QLA22xx connectors to the device are connected correctly. For example, the optical transmit connector on the board should be connected to the optical receive connector on the device. Some connectors require a firm push to ensure proper seating. An easy way to check is to switch the connectors on either the QLA22xx or the device, then reboot your system. If the BIOS is enabled, devices attached to the QLA22xx board are displayed on the screen.

Is the QLA22xx board installed correctly in the PCI slot? Is it seated firmly in the slot? Check for interference due to nonstandard PCI connectors.

Is the GBIC on the QLA2200G fully seated?

Are all external peripherals properly powered up? See appendix A.3 for information about displaying attached devices.

3.3

System Configuration Problem Checklist

All PCI-compliant systems automatically detect 32- or 64-bit boards and set the appropriate bus speed (33 or 66 MHz). Check the motherboard for proper configuration (see section 2.4).

See the documentation supplied with your computer, or contact your computer dealer to determine if your motherboard requires special configuration.

QLA22XX specifications

The Q-Logic QLA22XX series encompasses a range of high-performance Fibre Channel Host Bus Adapters (HBAs) designed to enhance data storage and network connectivity within enterprise environments. Specifically, these adapters are tailored for environments requiring robust storage solutions, ensuring that organizations can effectively manage their data traffic and optimize their storage strategies.

At the heart of the QLA22XX is its adherence to the Fibre Channel standard, which allows for high-speed connections between servers and storage devices. These adapters support speeds of up to 16 Gbps, which provides the bandwidth necessary for handling multiple workloads simultaneously. This capability is crucial for businesses that rely on rapid access to large volumes of data, thereby facilitating quicker decision-making processes and enhancing productivity.

The QLA22XX series features advanced technologies such as enhanced error correction and adaptive routing. These technologies ensure data integrity and reliability during transfer, reducing the likelihood of data corruption. Additionally, the adaptiveness of the routing capabilities allows the HBA to optimize performance by dynamically adjusting to various network conditions and topologies.

Another key characteristic of the QLA22XX is its compatibility with a multitude of operating systems, including major platforms like Windows, Linux, and VMware. This broad compatibility simplifies deployment across diverse IT ecosystems, making it easier for organizations to integrate these HBAs without extensive modifications to their existing infrastructure.

Moreover, the QLA22XX series supports the latest management and monitoring tools, enabling administrators to have complete visibility into performance metrics and potential issues. This includes support for the SNMP protocol, which facilitates proactive monitoring and management of the networked storage systems.

Energy efficiency is also a consideration in the design of the QLA22XX series. These adapters are engineered to minimize power consumption, which not only aids in reducing operational costs but also contributes to the organization's sustainability goals.

In summary, the Q-Logic QLA22XX series is a reliable and high-performance Fibre Channel HBA solution. With its high-speed connectivity, advanced technologies for data integrity, broad compatibility, and proactive management features, it stands out as a robust option for enterprises looking to enhance their data storage and network connectivity capabilities.
