IBM ValuePoint - Diagnostic and test information (6381,6382, 6384, 6387)
Applicable to: World-Wide
Diagnostics and Test Information (6381, 6382, 6384, 6387):
The following information is helpful when diagnosing computer problems on types 6381, 6382, 6384, and 6387. For Model 6384 P60/D, see ¿Diagnostics and Test Information (6384 P60/D)—.
Power-On Self Test:
Each time you power-on the computer, the power-on self test (POST) is initiated. The POST takes up to 90 seconds to complete, depending on the options installed.
The POST checks the following:
System board
Memory
Video
Hard disk drive(s)
Diskette drive(s)
Keyboard
Mouse
Parallel port
Serial port(s)
To start the POST, power-on the display and the computer. The following happens:
1. The following icon 
appears at the upper-right corner of the display. Pressing F1 at this time causes the Configuration Utility menu to appear after the POST has completed.
2. A count of the computer memory appears at the upper-left corner of the display.
3. If an error is detected, an error code appears under the computer memory count.
Note:
Memory errors appear as XXXXXX XXXX 201 in the upper-left corner of the display (X can be a number or letter).
4. Successful completion of POST is attained when there are no errors detected in the computer.
5. The computer attempts to load the operating system. If an operating system is not found, a graphic message (icon) is displayed requesting the user to insert a diskette into drive A and press the F1 key to resume operation.
6. If a critical error is encountered, the POST is halted.

3 - VERIFY DISKETTE TEST: Verifies data accessing and each sector.
4 - SPEED TEST: Measures the time required for one revolution of the diskette.
5 - DISKETTE CHANGE TEST: Tests the diskette change signal and write-protect feature as you remove and insert a diskette.
9 - RETURN TO CONTROL PROGRAM: Returns to the System Checkout menu or continues with the next device test.
Hard Disk Diagnostic Menu:
This menu allows you to test the hard disk drive and the integrated controller.
|
HARD DISK DIAGNOSTIC MENU |
1 - WRITE, READ, COMPARE (ON TEST CYLINDER): Tests the hard disk drive read and write operations.
2 - SEEK TEST: Sequentially moves the hard disk heads inward one cylinder at a time until the last cylinder is reached. The heads then reset to the first cylinder and a random seek test is performed.
3 - HEAD SELECT: Data is written to the test cylinder by each hard disk head; the data is then read and checked for any errors.
4 - ERROR DETECTION AND CORRECTION: Tests the hard disk error checking and correction circuits by reading data, altering the data, and writing the data on the test cylinder. A comparison test is made to detect any errors.
5 - RUN ALL TESTS: Runs tests 1, 2, 3, and 4; also reads track 0.
6 - READ VERIFY: A read operation is performed on the entire hard disk drive; any tracks that cannot be read are reported with
existing defects.
7 - FORMAT MENU: Selects the Format Selection menu for the hard disk drives.
9 - RETURN TO CONTROL PROGRAM: Returns to the System Checkout menu or continues with the next device test.
Formatting a Hard Disk Drive:
Hard disk drives normally contain tracks in excess of their stated capacity to allow for defective tracks. The user is notified by a
diagnostic message when the defect limit has been reached and service is recommended.
The Diagnostics Format program is different from the operating system format program. Before the customer can transfer information from the backup diskettes to the hard disk drive, the hard disk drive must be formatted using the operating system format program. Have the customer refer to the operating system manual for a description of the hard disk preparation commands.
Note:
The Diagnostics Format program on this diskette might damage non-IBM hard disk drives. Refer to the documentation that came with the drive for low-level formatting information.
Warning:
All data on the selected hard disk drive is destroyed during a format operation or surface analysis.
Format Menu:
|
FORMAT SELECTION MENU |
1 - CONDITIONAL FORMAT: The hard disk drive is scanned for any defective tracks, then formatted (except for any known defective tracks).
2 - UNCONDITIONAL FORMAT: The hard disk drive is formatted, except for any defective tracks that you specify.
3 - SURFACE ANALYSIS: Scans the hard disk drive by writing, reading, and comparing a unique data pattern to detect any defective tracks.
9 - RETURN TO HARD DISK MENU: Returns to the Hard Disk Diagnostic menu.
Warning:
Formatting results in a complete loss of data on the hard disk drive, including system programs. If you are directed to or elect to format the hard disk drive, you must do the following:
1. Prior to formatting, have the customer back up all information, if possible.
2. Prior to returning the computer to the customer, you must reinstall the system programs on the hard disk.
Formatting Procedure:
Before replacing a failing hard disk drive, try to format it as follows:
1. Power-off the computer. Check that the hard disk drive cable is tightly connected.
2. Insert the Diagnostics diskette into drive A.
3. Power-on the computer.
4. Press 0 (SYSTEM CHECKOUT), then press Enter.
5. Depending on the options installed in the computer, questions about attached devices appears on the screen. Answer as required, then press Enter.
6. If the list is incorrect, run the Configuration Utility program. Check to see if any adapter or device is set to a conflicting address with any other adapter or device. Also be sure that any adapter or device missing from the list is not set to ¿disabled—. Press Y (IS THE LIST CORRECT (Y/N)?) , then press Enter.
7. Press 0 (RUN TESTS ONE TIME) , then press Enter.
