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 an 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 converts
the logged information 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 the sysplanar0 diagnostics are running in Problem Determination
Mode.
Display Microcode Level
This service aid enables you to display the current level of microcode on an adapter or
device. See the following command syntax:
diag -c -d
device_name
-T "disp_mcode"
Display or Change Bootlist
This service aid allows the bootlist to be displayed, altered, or erased.
The system attempts to perform an IPL from the first device in the list. If the device is
not a valid IPL device or if the IPL fails, the system proceeds in turn to the other
devices in the list to attempt an IPL.
