Display Microcode Level; Display Multipath I/O (Mpio) Device Configuration; Display Or Change Bootlist - IBM pSeries 690 User Manual

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.

Display MultiPath I/O (MPIO) Device Configuration

This service aid displays the status of MPIO devices and their connections to their parent devices.
This service aid is capable of sending SCSI commands on each available path regardless of the default
MPIO path algorithm. Therefore, it is useful for testing the unused path for integrity.
Run this service aid if it is suspected that there is a problem with the path between MPIO devices and
their parent devices.
This service aid is capable of:
v Listing MPIO devices
v Listing the parents of MPIO devices
v Displaying the status and location of specified MPIO devices
v Displaying the hierarchy of MPIO adapters and devices.
If there are no devices with multiple paths, this service aid will not be shown on the "Task Selection" menu.
Access this service aid directly from the AIX command line, by typing:
/usr/lpp/diagnostics/bin/umpio

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.
