Use this service aid when there isno need to see the vital product data (VPD). (No VPD is displayed.)Display Firmware Device Node InformationThis task displays the firmware device node information. This service aid is intended to gather moreinformation about individual or particular devices on the system. The format of the output data may differdepending on which level of the AIX operating system is installed.Display Hardware Error ReportThis service aid uses the errpt command to view the hardware error log.The Display Error Summary and Display Error Detail selection provide the same type of report as the errptcommand. The Display Error Analysis Summary and Display Error Analysis Detail selection provideadditional analysis.This service aid provides a means to view hardware errors logged against a resource or set of resourcesand displays a summary screen of all hardware errors logged against any resource in the list. From thesummary screen, errors can be selected to be viewed in more detail. The detailed output is acquired usingerrpt -a. On both the error summary and error detail screens, errors that generated a diagnosticconclusion will have this information presented with the error. Depending on the environment and thesoftware packages installed, selecting this task displays the following subtasks:v Display Hardware Errors for Any Resourcev Display Hardware Errors for PCI-X SCSI RAID Adaptersv Display Hardware Errors for PCI-X SCSI AdaptersDisplay Hardware Errors for Any ResourceThis subtask allows the user to select any resource or set of resources for the purpose of displaying theirhardware errors.Chapter 7.
