Configuring an EMC Boot Device

If a system contains of mixture of detected and undetected adapters, any existing

EFI drivers loaded by EFI should be unloaded using the EFI Shell drivers, and unload commands. If you have not previously installed EFI boot code to your QLogic HBA, skip this section.

1.Type drivers at the EFI shell prompt to display the list of loaded EFI drivers. You will see an entry (or entries) similar to the following:

5D

2.The first column (in this example, 5D) is the driver handle for the HBA. To unload the EFI boot code driver, use the unload command:

unload 5D

3.After all instances of the QLogic EFI boot code driver are unloaded, proceed to the next section.

To flash the HBA with the latest EFI boot code, copy the files from the EFI boot code package to a floppy disk. If your system does not have a floppy drive, a USB pen drive can be used instead. If your system is already booted to the EFI shell, insert the floppy or USB pen drive and type exit to exit the EFI shell. From the boot options menu, select EFI Shell [Built-in]to go back into the EFI shell. This will cause the EFI shell to re-discover disk devices and will locate the floppy or pen drive.

When you enter the EFI shell, the device map should be displayed. If it does not display, type map at the shell> prompt to display the list of detected devices. Disk devices that are accessible by the EFI shell are listed as FS devices. Switch to the device containing the EFI boot code. This is accomplished by typing the name of the device and a colon. For example, if the EFI boot code is on fs1, type fs1: and press ENTER to switch to that device. If your HBA does not have EFI boot code already installed, you must use the EFIUTIL.EFI driver utility in order to flash the board. At the command prompt, type EFIUTIL and press ENTER. This will load the QLogic EFI utility and display a efiutil> prompt. The following commands assume that the EFI boot package files are all located in the same directory as the EFIUTIL.EFI program.

QLogic specifications

EMC QLogic is a leading provider of advanced networking solutions, primarily known for its high-performance storage area network (SAN) technologies. It specializes in Fibre Channel and Ethernet networking products, offering robust solutions that are essential for modern data center environments.

One of the key features of EMC QLogic is its exceptional performance in high-speed data transfer. QLogic's Fibre Channel products, such as switches and host bus adapters (HBAs), support speeds of up to 32 Gbps, ensuring ultra-fast communication between storage devices and servers. This high throughput is crucial for applications demanding high IOPS (Input/Output Operations Per Second), particularly in virtualized environments and databases.

Another prominent aspect of EMC QLogic's technology is its support for advanced features like Data Center Bridging (DCB). DCB enables the convergence of storage and traditional Ethernet traffic on a single network, streamlining data center management and reducing costs. By allowing both storage and data networking to coexist on the same infrastructure, EMC QLogic enhances efficiency and simplifies network architecture.

Scalability is another characteristic that sets EMC QLogic apart. The architecture is designed to support a wide range of deployment sizes, from small businesses to large enterprise data centers. This scalability ensures that organizations can grow their IT infrastructure without needing to overhaul their existing deployment.

EMC QLogic also places a strong emphasis on reliability and security. Their products are built with redundancy and failover mechanisms, which minimize downtime and ensure continuous operation even in the event of hardware failure. Additionally, security features such as encryption and access controls are integrated to protect sensitive data as it travels across the network.

Management and monitoring capabilities are also integral to EMC QLogic's offerings. The company provides advanced software tools for managing network resources, allowing administrators to monitor performance, diagnose issues, and optimize configurations efficiently. This helps organizations maintain peak performance and reduces operational complexity.

In summary, EMC QLogic combines high-speed performance, advanced features, and robust reliability in its networking solutions. With a focus on scalability and security, it provides organizations with the tools necessary to build and manage efficient, modern data centers that can adapt to evolving technological demands. Its commitment to innovation positions EMC QLogic as a trusted partner in the storage networking landscape.
