User Service Guide, Third Edition - HP Integrity cx2620 Server

Verifiers quickly determine whether or not a specific device is operational by performing tasks
similar in nature to the way applications use the device. No license is required to run the verifiers.
Diagnostics are tools designed to identify faulty or failed CRUs.
Exercisers stress devices in order to facilitate the reproduction of intermittent problems.
Information modules create a log of information specific to one device, including:
• The product identifier
• A description of the device
• The hardware path to the device
• The vendor
• Onboard log information (if applicable)
• Miscellaneous information associated with the device
• The firmware revision code, if firmware is present in the device, is also displayed
Expert tools are device-specific troubleshooting utilities for use by sophisticated users. Their
functionality varies from tool to tool, but they are intended to be interactive, and rely on users
to provide information necessary to perform a particular task. These tools require users to have
the appropriate license, if they wish to run them.
Online Support Tool Availability
Online diagnostics are included in the HP-UX OE media, and are installed by default.
