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 task is used to display the microcode or firmware levels of currently installed
resources. When the sys0 resource is selected, the task displays the levels of both the
system firmware and service processor firmware. sys0 may not be available in all
cases.
You can display the current level of the microcode on an adapter, the system, or a
device by using the AIX diag command. See the following command syntax: diag -c
-d
device
-T "disp_mcode"
Flag Description
-c No console mode.
-d Used to specify a device.
-T Use the disp_mcode option to display microcode.
The AIX lsmcode command serves as a command line interface to the ″Display
Microcode Level″ task. For information on the lsmcode command, refer to the
AIX
Commands Reference
manual.
