Troubleshooting

 

 

 

 

 

 

 

 

Solution Upgrade to the latest HBA driver. This was corrected for Windows

 

 

 

2000 in 8.2.2.25 and later drivers. Windows 2003 driver 8.2.2.20 and

 

 

 

later already contain this correction.

 

 

 

 

 

 

Problem 4

 

EMC Primus case emc69308 — Direct-connect to EMC CLARiiON

 

 

 

CX200 reports incorrect queue full error messages. Even under light

 

 

 

I/O, a host may log a message noting that disk has reached a

 

 

 

queue-full state similar to the following in the Windows event

 

 

 

viewer:

Event ID: 11

Source: ql2300

Description: The driver detected a controller error on \Device\Scsi\ql2300x.

Data (words): offset 34 = F003001C [ErrorCode: Target device queue full].

Solution

Upgrade to the latest HBA driver. This was corrected in version

 

8.2.2.25 and later drivers.

 

 

Problem 5

Windows 2000 Hosts running less than SP4 could be susceptible to

 

data loss during LUN expansion operations.

Solution

This issue is corrected by Microsoft in SP4, or by applying hotfix

 

327020. Refer to EMC Solution IS emc73538 and Microsoft

 

Knowledge Base article 327020 for more information.

Problem 6

For Windows 2003, the STORPort drivers 8.2.3.26 with Microsoft

 

hotfix Q823728 and earlier do not yet fully support all Microsoft VSS

 

functions.

 

Solution This was first corrected in Microsoft QFE hotfix Q837413 and to be

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.
