Display Hardware Errors for PCI-X SCSI RAID Adapters

This subtask allows the user to select only PCI-X SCSI RAID adapters for the purpose of displaying their
hardware errors. Hardware errors for the first generation children of any resource(s) selected are also
displayed. Since not all PCI-X SCSI RAID adapter errors are logged against the resource itself, this
subtask functions to make it easier to diagnose problems with a PCI-X SCSI RAID adapter.

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 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.

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.
