Display Hardware Vital Product Data
This service aid displays all installed resources along with any VPD for those
resources. Use this service aid when you want to look at the VPD for a specific
resource.
Display Machine Check Error Log
Note: The Machine Check Error Log Service Aid is available only on Standalone
Diagnostics.
When a machine check occurs, information is collected and logged in a NVRAM
error log before the system unit shuts down. This information is logged in the AIX
error log and cleared from NVRAM when the system is rebooted from the hard disk,
LAN, or standalone media. When booting from Standalone Diagnostics, this service
aid can take the logged information and turn it into a readable format that can be
used to isolate the problem. When booting from the hard disk or LAN, the
information can be viewed from the AIX error log using the Hardware Error Report
Service Aid. In either case the information is analyzed when running the sysplanar0
diagnostics in Problem Determination Mode.
Display Microcode Level
The following usage statements describe the syntax of the command to display the
current level of microcode on an adapter or device.
