Trespassing the Boot LUN Using atf_trespass

Configuring an EMC Boot Device

With FC-series array core code 8.44.x and earlier, you will use the atf_trespass command to trespass the boot LUN. To do this, follow the steps under Trespassing the Boot LUN Using atf_trespass on page 3-33.

Each HBA can support multiple entries; you should configure Boot Port Name entries connecting to multiple ports on both SPs for maximum redundancy in booting after a boot LUN trespass or other link failures. Refer to Table 3-1 on page 3-37 to determine your high-availability requirements.

7.When all parameters are set correctly and you have added Boot Port Name entries for all the SP ports from which you would like to attempt to boot, press ESC to return to the Fast!UTIL Options menu; then select Save Changes to save the changes you made to the current adapter.

8.Press ESC to exit the Fast!UTIL Options menu.

9.Reboot the server.

Follow these steps to use the atf_trespass command to trespass the boot LUN:

1.Boot the host and log in to Windows.

2.Windows NT 4.0 will have the boot LUN configured for ID 0 as described under Preparing the Storage System on page 3-17.

For Windows 2000, follow these steps to determine the LUN ID of the boot LUN as seen by the host:

a.From the Windows task bar, select Start, Programs, Administrative Tools, Computer Management.

b.On the Computer Management window, click Disk Management.

c.Locate the System disk in the list. This is typically Drive C:\ and will be noted with (System).

d.Select the Disk X description area, and from the Action menu, select Properties.

A display appears with a line similar to the following:

Device Type: SCSI (Port: 3, Target ID: 1, LUN:0)

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.
