PCServer500 - Software/Diagnostics (S/390)
Applicable to: World-Wide
Software Facilities (Server System/390)
Note
Knowledge of System/390 and CP/390 architecture is essential to the proper use of these processor control functions. Information about System architecture is found in IBM Principles of Operation, GA22-7201.
VM/ESA and VSE/ESA use the same problem determination tools on the PC Server/390 for debugging 390 operating system and applications problems as they do on 390 mainframe systems.
Standard OS/2 debugging tools can be used to assist with problems with the 390 environment on the PC Server/390 since many of the functions use OS/2 facilities and PC Server devices. The 390 Processor Complex Programs also have the following tools for controlling and debugging the system.
|
390 Manual Operations |
Provides the function of the 390 hardware console as on mainframe systems. |
|
390 Status Window |
Displays the processor status word (PSW) and current status of the 390 processor. |
|
390 I/O Trace |
Used to trace I/O request between the 390 processor and its I/O subsystem. The trace can be selected by device and can be written to an OS/2 file. It can also be displayed in a Presentation Manager window by selecting the |
|
Snap Shot Dump |
Creates a binary file of the I/O subsystem to be used by IBM support personnel during problem determination. This program is selected by clicking on the Snap Shot Dump icon. |
Microprocessor Complex Diagnostics (S/390)
The IBM P/390 Advanced Diagnostics and Options Diskette contains the programs used to test the S/390 Microprocessor Complex installed in the computer, and the ADF and DGF files required for configuration. To run the S/390 Microprocessor Complex Diagnostics programs, see 'Advanced Diagnostics and Options Diskette (S/390).—
Advanced Diagnostics and Options Diskette (S/390)
The Advanced Diagnostics and Options Diskette is a self-booting diskette that contains the P/390 diagnostic programs. The diagnostic programs are designed to be used with the diagnostic diskette and diagnostic information in the IBM PS/2 Hardware Maintenance manual for the computer you are servicing. The results of the diagnostic tests are reported as a success or failure.
To run the P/390 diagnostic programs, do the following.
Note
First run the diagnostics program for the computer you are servicing. If the P/390 card is recognized by the configuration program (the P/390 appears on the installed devices list), the diagnostics program will instruct you to run the P/390 Diagnostics and Option diskette. If the P/390 card is not recognized by the configuration program (does not appear on the installed devices list), go to 'Error Reporting (P/390)—.
1. Power-off the computer; then power-off all external devices.
2. Insert the P/390 Diagnostics and Option diskette into drive A.
3. Power-on all external devices; then power-on the computer.
4. When the Main Menu appears, a. Select2
b. After the information message, press Enter.
c. SelectE to run the diagnostic programs with expanded messages.
The diagnostic program will test the adapter and terminate with the message "P/390 in slot X successfully passed all tests, or a failure message that includes an error message and error code. The error message will identify the failing FRU.
d. If a failure message is displayed, it identifies the failing FRU(s) as:
1. The adapter card, excluding the memory card
2. The memory card
3. Both the adapter card and the memory daughter card (when the failure cannot be isolated).
e. Record the error code and replace the identified FRU.
