The Dell 32-Bit Diagnostics tests provide several types of guidance for administrators, such as help in determining whether devices are functional determining device versions and other identity information determining mean time to failure (MTTF) and extracting system event logs (SELs) into human-readable form.

POWER SOLUTIONS 1ΔΆ System state OS, drivers, applications, and hardware are required Only physical hardware is required Tier 3 Hardware diagnostics and system information (delivered in software applications post-os) Tier 2 Hardware diagnostics (delivered on utility partition pre-os) Results of diagnostic tests, including any errors detected, can be easily viewed by selecting the Information tab in the tool s main menu. Reprinted from Dell Power Solutions, February Copyright 2005 Dell Inc. Because tier 2 diagnostics are OS independent, they are particularly useful in the pre-os environment. These tools provide diagnostic modules that focus on specific subsystem and functional areas of the server and hence provide direction for administrators during root-cause analysis of a server failure. Tier 2 server diagnostic tools Tier 2 offers comprehensive hardware diagnostic tools that can be used to determine the current status of PowerEdge and PowerEdge SC servers. While administrators can disable reporting of many tier 1 diagnostics during BIOS or Embedded Server Management (ESM) setup, best practices dictate that diagnostics remain configured as active to enable efficient hardware support. The server reports the results of tier 1 diagnostics by logging error messages in system logs, by displaying messages on the LCD, and by selectively illuminating the Dell Active ID or power button LED. These diagnostics are always available as long as the server is powered up. No additional software or hardware needs to be installed to take advantage of tier 1 features. Tools in each tier are designed to address unique diagnostic needs that arise during different stages of the server deployment and life cycle (see Figure 1): Tier 1 tools: Provide a basic assessment of system functionality in a pre operating system (OS) environment Tier 2 tools: Support comprehensive hardware diagnosis and help inform hardware technical support decisions in a pre-os environment Tier 3 tools: Provide comprehensive hardware diagnosis, real-time monitoring and reporting, and predictive failure alerts in a post-os environment Tier 1 server diagnostic tools Tier 1 diagnostics comprise hardware detection tools that are built into Dell PowerEdge and PowerEdge SC server firmware.

Enterprise diagnostic tools are divided into three tiers. In addition, Dell server diagnostic tools can enable effective fault isolation and root-cause analysis after hardware failures occur.

Dell server diagnostic tools are designed to provide early warning of server health conditions so that impending problems can be corrected before they cause downtime. BY KOMAL PATEL AND PRAMADA SINGIREDDY Server diagnostic tools can help IT organizations troubleshoot a wide range of potential problems that may arise in enterprise production environments. This article discusses various tools available for server diagnostics at the tier 1, tier 2, and tier 3 levels, along with best practices for the use of server diagnostic tools. 1 Troubleshooting Enterprise Production Environments Using Dell Server Diagnostic Tools Dell server diagnostic tools are designed to enhance fault isolation and root-cause analysis in enterprise production environments.
