PC Server 704 - Diagnostics (QAPlus/PRO & RAID)

Applicable to: World-Wide

Diagnostics (QAPlus/PRO)

The following tools are available to help identify and resolve hardware-related problems:
Power-on self-test (POST)
POST beep codes
Test programs
Error messages
Diagnostics Diskette

Power-On Self-Test (POST)
Each time you power-on the system, it performs a series of tests that check the operation of the system and some options. This series of tests is called the power-on self test, or POST. POST does the following:
Checks some basic system-board operations
Checks the memory operation
Starts the video operation
Detects and initializes ISA devices
Detects and configures EISA devices
Detects and configures PCI devices
Verifies that the diskette drive, hard disk drive, and other installed devices are working

Check the indicator lights on the front of the server and the back of the power supplies. Verify that all server devices are operating properly. If a device is not operating properly, ensure that it is not defective and is installed correctly. Replace defective devices and reinstall any device that is not installed correctly.

If POST finishes without detecting any problems, a single beep sounds and the first screen of the operating system or application program appears. If no operating system is installed, the system prompts you to insert a startable diskette.

If POST detects a problem, an error message appears on the screen. A single problem can cause several error messages to appear. When you correct the cause of the first error message, the other error messages probably will not appear on the screen the next time you power-on the system.

POST Beep Codes
The Power-On Self-Test generates a beeping sound to indicate successful completion of POST or to indicate that the tests detect an error.

One beep and the appearance of text on the display indicates successful completion of the POST. More than one beep indicates that the POST detects an error.

Test Programs
The QAPlus/PRO test programs, developed by DiagSoft for IBM, are the primary method of testing the PC Server. You can use them to test the IBM components of the system and some external devices. The amount of time required to test all components depends on the number of components. The more optional adapters and devices you have attached to your
system, the longer the testing takes.

The test programs on the Diagnostic Diskette include the following features:

Feature	Description
Advanced Diagnostic Tests	Identifies most problems associated with the following major components: System board Hard disk drives Diskette drives CD-ROM drives RAM Serial and parallel ports Video adapter Printer Keyboard Mouse
Flexible Test Control	Allows you to: Run groups of tests in batch Specify parameters to use for each test (for example, video modes, disk cylinders, port addresses and so on.) Specify the number of passes you want to run ( one to continuous) Log the test results to a text dBase (DBF) format file Save all test settings for future use View System Information View the server's configuration information. (For example, you can view the IRQ/DMA assignments, memory usage, device drivers, and so on.) Select System Utilities Format a diskette

Error Messages
Messages generated by the software - the operating system or application programs - generally are text messages, but they also can be numeric. Basically, there are five types of error messages.
POST error messages
Diagnostic error messages
POST beep codes
Software generated messages.
Multiple messages

Error Message	Description
POST Error Messages	Displayed when POST finds problems with the hardware or detects a change in the hardware configuration.
POST Beep Codes	Sounds emitted from the speaker if POST finds a problem. One beep indicates POST completed successfully. Multiple beeps indicate a problem was found by the POST.
Diagnostic Error Messages	Displayed when a test program finds a problem with a hardware option.
Software Generated Error Messages	Displayed if a problem or conflict is found by an application program, the operating system, or both. For an explanation of these messages, refer to the information supplied with that software package.
Multiple Messages	The first error that occurs can causes additional errors. Follow the suggested action of the first error displayed. In this case, the system displays more than one error message. Always follow the suggested action instructions for the firsterror message displayed.

Return Codes
For the test programs to properly determine if a test Passed, Failed , or Aborted , the test programs check the error-return code at test completion. To register the test properly in the test log, the test programs must generate one of the following return codes:

Return Code	Description
0	Indicates that the device passed its test.
1	Indicated that the device failed its test.
2 or greater	Indicates that the test stopped or was aborted.

Using the Test Programs
The test programs provide advanced functions and utilities for power users and service or support professionals to troubleshoot even the most difficult problems.

Program Navigation
You can maneuver within the test programs by typing the first letter of a menu choice, using the function keys, or using command-line options.

Using the First Letter of a Menu Choice
Throughout the test programs, pressing the first letter of an option on a menu is the same as moving to that item with the cursor and pressing Enter; however, this function is not enabled on Test Group Screens.

Using the Function Keys
Use the following keys to maneuver throughout the test programs:

Keys	Action
Enter	Select an item, run the test module or run the test.
Down Arrow	Moves the cursor down
Up Arrow	Moves the cursor up
F1	Calls up the appropriate Help information. Use the up arrow key or the down arrow key to scroll through the information. Pressing F1 from within a Help screen provides a help index from which you can select different categories. One of the important help categories is function key usage. Pressing Esc exits Help and returns to where you left off.
Esc	Go back to the previous menu

Additional functions are available in the Test Module Selection screen and the Test Group screen using the following keys:

Keys	Action
Tab	Move to test group (or move to parameters)
Spacebar	Toggle modules on/off (or toggle tests on/off)
F2	View test results log
F10	Local menu
+	Next logical unit number (for example, LUN 1, LUN 2, and so on)
-	Previous logical unit number

Command Line Options
The following Command Line Options allow you to define specific conditions for running the diagnostic programs at startup time. At the operating system prompt, type QAPRO /XXX (where /XXX represents one of the following commands); then press Enter:

Command	Action
/B&W	The /B&W option forces the program to load in black and white (monochrome) mode.
/LOG= file	The /LOG= file option directs the test file programs to start using a specified Error Log file.
/INT10	The /INT10 option forces the test programs to use the Basic Input/Output System (BIOS) for screen writes.
/O XXX	The /O XXX option, where XXX =test group, omits the designated test group from testing.
/OALL	The /OALL option omits all test groups from testing.
/I XXX	The /I XXX option, where XXX =test group, includes the designated test group. When used in conjunction with the /OALL option, you can specify the tests that you want to include. These options are helpful if you have insufficient memory available to load all of the test programs simultaneously, or if you want to test specific test groups. The valid test groups are: LPT Parallel port COM Serial ports HDU Hard disk (IDE only) FDU Diskette drive VID Video MBD System board KBD Keyboard PDV Pointing device or mouse MEM Memory SCU SCSI CDR CD-ROM SYS System information/Utilities You can include this option multiple times. For example, to run the keyboard, SCSI, and CD-ROM test groups, type: QAPRO.EXE /OALL /IKBD /ISCU /ICDR
/USRCONFIG= file	The /USERCONFIG= fileoption tells the test programs to look for a user diagnostic configuration file other than the default USERDIAG.CFG.
/SCRIPT= file[,R]	The /SCRIPT= file[,R] option with the[,R] runs the selected script. Note: You can use a "-" instead of a '/— as the command line switch.

Viewing the Test Groups
As you move the cursor bar up or down in the Test Module Selection window, the right hand screen changes to show the attributes, parameters, and the selected tests of the corresponding Test Group. The diamond mark indicates a module selected for testing.

The indicated attributes are characteristics of the selected test module that are used by the test programs to determine which tests to run or how to run selected tests. Attributes are also used to limit the allowable range of parameters (for example, - ending cylinder).

Parameters are values you select to establish the scope of tests. For example, you can select Extended Memory testing parameters and limit the testing to a specific range of test blocks by specifying the starting and ending memory block. This might be appropriate if prior experience indicates that problems are likely to exist in a specific area of memory. By selecting these limiting parameters, you reduce memory testing time.

Scripting
Scripting allows you to select specific groups of tests, testing parameters, and options. Your selection is saved for later use as a test Script. To set up a test script, first select all the appropriate test groups and specific tests you want to run from the Module Testing section under Diagnostics. You should also select appropriate testing parameters and options.

Changing Logical Unit Numbers
In some instances, you can have more than one logical unit number (LUN) for a particular module. LUNs represent individual devices within a test group or module. For example, you might have two diskette drives or two hard disk drives; or, you might have base, extended, shadow, and cache memory installed in the computer. This configuration might result in as many as four or five different LUNs in the Memory Test Group. Or you might have base, extended, shadow, and cache memory installed in the system which might result in as many as four or five different LUNs in the Memory Test Group.

From either the Module Test Menu or the Test Group window, you can change to a different LUN (where applicable) by pressing the plus (+ ) key (next LUN), or the minus (- ) key (previous LUN).

Test Group Specifications
In the upper-right-hand portion of the testing screen (or just the upper portion if you switched to an individual test group screen) are the specifications for the related test group.

Note: In the Hard Disk Test Group specification area, if a software program was to compress your drive, the indicated size is the compressed size of the logical drive.

Running RAID Subsystem Diagnostic Tests
The ServeRAID Subsystem Diagnostic program provides several utility programs that allow you to test the ServeRAID adapter and the devices connected to it.

To run the RAID diagnostic utility programs, do the following steps:

Start the ServeRAID configuration program (see 'Starting the ServeRAID Configuration Program—).

Select Advanced Functions from the Main Menu.

Select IBM RAID Subsystem Diagnostic.

Select the diagnostic test that you want to run and press Enter: Run Adapter Self-test runs diagnostic tests on the ServeRAID adapter. SCSI Device Self-test runs diagnostic tests on the SCSI devices attached to the ServeRAID adapter. Drive Media Test verifies that all sectors on a hard disk drive can be accessed. The drive must be in the RDY or HSP state. Format Drive performs a low-level format on a hard disk drive. For more information, see 'Formatting Drives—. Follow the instructions on the screen.2.

Additional Disk-Array Tasks
The following procedures are for performing additional, less common, disk-array tasks. You can select several utility programs:
Back up configuration to diskette
Restore configuration to diskette
Change the write policy
Change the RAID parameters
Format a drive
Obtain drive status
Change the RAID adapter parameters

Attention
	Notices appear throughout the following procedures to alert you about potential loss of data. Similar messages appear on the screens for these procedures. Read these messages carefully before answering yes to the confirmation requests.

Backing Up The Disk-Array Configuration
The RAID adapter maintains a record of the disk-array configuration information in its nonvolatile RAM (NVRAM) and electrically erasable programmable read-only memory (EEPROM) module. The disk-array configuration is vital information. To protect this information, back up the information to diskette as soon as you have completed your tasks.

To back up the disk-array configuration information to diskette:

Note
	You need a blank, formatted, 3.5-inch diskette.

1. Label a blank diskette 'Disk Array Configuration Backup,— and date it.
2. Start the ServeRAID configuration program (see 'Starting the ServeRAID Configuration Program—).
3. Select Advanced Functions from the Main Menu.
4. Select Backup config. to diskette.
5. Remove the configuration program from the drive and insert the blank diskette.
6. Follow the instructions on the screen.
