Chapter 5. Diagnostics
This chapter describes the diagnostic tools that are available to help you solve
problems that might occur in the DPI blade.
Note: The DPI blade uses shared resources that are installed in the BladeCenter
unit. Problems with these shared resources might appear to be in the DPI blade
(see "Solving shared BladeCenter resource problems" on page 58 for information
about isolating problems with these resources). See the Problem Determination and
Service Guide or the Hardware Maintenance Manual and Troubleshooting Guide for
your BladeCenter unit and other BladeCenter component documentation for
diagnostic procedures for shared BladeCenter components.
If you cannot diagnose and correct a problem by using the information in this
chapter, see Appendix A, "Getting help and technical assistance," on page 63 for
more information.

DPI blade diagnostics program
The DPI blade diagnostics program is an essential tool for identifying and isolating
hardware problems. The DPI blade diagnostics program is based on a custom
RAVE application that is developed by CloudShield. It circulates packets at
maximum rate to the various processing elements and provides an output screen
on the Web Management Interface that displays the statistics of a number of
packets that have been processed. This test exercises the major processing
elements of their associated memory banks and the data paths. If there are errors,
you can view them from the Applications page in the Web Management Interface.

The DPI blade diagnostic program circulates test packets to various processing
elements and returns statistics about the processing of the packets.
These tables list problem symptoms and actions to correct the problems. See
"Troubleshooting tables" on page 45 for more information.
The diagnostic programs are the primary method of testing the major
components of the DPI blade. These programs are stored in Cloudshield Packet
Operating System (CPOS), in the host blade server.
