Strategy for Replacing FRUs for CTO, CMV, and GAV products

Product definition

Dynamic Configure To Order (CTO)

This provides the ability for a customer to configure an IBM solution from an eSite, and have this configuration sent to fulfillment, where it is built and shipped directly to the customer. The machine label, PC Entitlement Warehouse (PEW), eSupport, and the HMM will load these products as the 4-digit MT and 3-digit model, where model = ’CTO’ (Example: 1829-CTO).

Custom Model Variant (CMV)

2 Hardware Maintenance Manual

This is a unique configuration that has been negotiated between IBM and the customer. A unique 4-digit MT and 3-digit model is provided to the customer to place orders (Example: 1829-W15). A CMV is a special bid offering. Therefore, it is NOT generally announced.

v The MTM portion of the machine label is the 4-digit MT and 3-digit

model, where model = ’CTO’ (Example: 1829-CTO). The PRODUCT ID portion of the machine label is the 4-digit MT and 3-digit CMV model (Example: 1829-W15).

v The PEW record is the 4-digit MT and 3-digit model, where model =

’CTO’ (Example: 1829-CTO).

v eSupport will show both the CTO and CMV machine type models

(Example: 1829-CTO and 1829-W15 will be found on the eSupport site.)

v The HMM will have the 4-digit MT and 3-digit CTO model only

(Example: 1829-CTO). Again, CMVs are custom models and are not found in the HMM.

General

Announce Variant (GAV)

This is a standard model (fixed configuration). GAVs are announced and offered to all customers. The MTM portion of the machine label is a 4-digit MT and 3-digit model, where model = a “fixed model number”, not ’CTO’ (Example: 1829-F1U). Also, PEW, eSupport, and the HMM will list these products under the same fixed model number.

FRU Identification for CTO, CMV, and GAV products

There are three information resources to identify which FRUs are used to support CTO, CMV, and GAV products. These sources are PEW, eSupport, and the HMM.

Using PEW

v PEW is the primary source for identifying FRU part numbers and FRU

descriptions for the key commodities for CTO, CMV and GAV products at a MT

- serial number level. An example of key commodities are hard disk drives, system boards, microprocessors, Liquid Crystal Displays (LCDs), and memory.

v Remember, All CTO and CMV products are loaded in PEW under the 4-digit

MT and 3-digit model, where model = ’CTO’ (Example: 1829-CTO). GAVs are loaded in PEW under the 4-digit MT and 3-digit model, where model = a “fixed model number”, not ’CTO’ (Example: 1829-F1U).

v PEW can be accessed at the following Web site:

http://w3-3.ibm.com/pc/entitle

Click on MACHINE LOOKUP, followed by WARRANTY INFORMATION. Input the MT and Serial number and the list of key commodities will be returned in the PEW record under COMPONENT INFORMATION.

v Business Partners using Eclaim will access PEW when performing Entitlement

Lookup. Business Partners will enter Loc ID, MT and Serial, and the key commodities will be returned in the Eclaim record under SYSTEM DETAILS.

v Authorized IBM Business Partners can access Eclaim at the following Web site:

http://wca.eclaim.com

Using eSupport

For Key Commodities (Examples - hard disk drive, system board, microprocessor, LCD, and memory)

v eSupport can be used to view the list of key commodities built in a particular

machine serial (this is the same record found in PEW).

v eSupport can be accessed at the following Web site:

http://www.ibm.com/pc/support

v To view the key commodities, click on PARTS INFORMATION, then PARTS

LOOKUP. Type in the model type and serial number. The key commodities will be returned in the eSupport record under PARTS SHIPPED WITH YOUR SYSTEM.

Chapter 1. About this manual 3

For the Remaining FRUs (the complete list of FRUs at the MT Model level)

v eSupport can be used to view the complete list of FRUs for a machine type and

model.

v To view the complete list of FRUs, type in the machine type and model

(Example: 1829-CTO) under QUICK PATH. Under ’View by Document Type’ select PART S INFORMATION. Under ’Filter by Category’ select SERVICE PARTS. Under ’Parts Information by Date’ select SYSTEM SERVICE PARTS. The list of service parts by description, with applicable machine type model and FRU will be displayed.

Using the HMM

v Use the HMM as a back-up to PEW and eSupport to view the complete list of

FRUs at the MT Model level.

Attention

The drives in the computer you are servicing might have been rearranged or the drive startup sequence changed. Be extremely careful during write operations such as copying, saving or formatting. Data or programs can be overwritten if you select an incorrect drive.

Diagnostic error messages appear when a test program finds a problem with a

hardware option. 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. See “Diagnostic error codes” on page 49.

General error messages appear 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.

The configurable capabilities of FDAT allow users to enable or disable specific tests, enable or disable testing features, control the test log detail, alter testing parameters, etc. FDAT will test for and report most commonly found errors on a fixed-disk drive and is able to test up to 128 SCSI and 4 IDE drives (up to 132 total drives).

Drive information is gathered through FDAT’s enumeration of available devices and user specific configuration parameters located in the FDAT.INI. FDAT uses information supplied by these features to indicate specifically what devices are available for test, what tests are available for the device, device properties, etc. Modify the FDAT.INI file in PC Doctor for DOS to change testing parameters.

FDAT consists of the following subtests and features.

Fixed-Disk Tests:

v Seek Tests: - checks the physical operation of the drive head.

– Linear Seek – Random Seek – Min-Max Seek – Butterfly Seek

Verify Tests: - checks the integrity of the data present on the media.

– Linear Verify – Random Verify

Surface Scan Tests: - checks the drive media for defects.

– Surface Scan (Linear) – Surface Scan (Aggressive) - this is disabled for normal customer use. – Surface Scan (Random)

SMART: - checks the SMART functionality for drives that support SMART.

– Start SMART Self-Test – Get SMART test results

Test Features:

Other

v Write-Splice Repair - detects and corrects Error Correction Code errors during

Verify tests.

v Auto Spin Down - a gradual spin down of the drive platters to avoid damaging

the media.

v Manufacturer Log - an in-depth manufacturer supported log of errors on the

drive.

Multitasking:

To allow simultaneous testing of multiple hard drives whenever possible, the FDAT module is written as a set of multitasking functions. Each drive under test can run the same test or run a different test at the same time. Each subtest is written to handle a single test pass and all test variables are kept track of in a

Chapter 4. IBM Enhanced Diagnostics 15

structure unique for each drive. However, when testing IDE drives, FDAT will not perform simultaneous testing of IDE drives that are attached to the same IDE cable. For example, if FDAT is testing four IDE drives on a PC, it will perform simultaneous testing on drives 1 and 3 first (master drives), then perform tests on 2 and 4 (slave drives). FDAT will also perform simultaneous testing on a master and slave that are on separate IDE cables, but will not perform simultaneous tests on a master and slave on the same IDE cable. This generally increases the amount of time needed to test multiple IDE drives.

Another limitation of FDAT’S multitasking capability is the use of Ultra DMA (UDMA). Only one drive at a time can access the UDMA channel and the UDMA channel buffer must be kept high in order to maintain a speed advantage over other data transfer modes. In order to use the UDMA channel during testing, users must disable the multitasking feature.

Destructive vs non-destructive testing:

Most of the tests found in FDAT are non-destructive. This means that PCDR will preserve any data that is present on the tested media prior to beginning any destructive operations (i.e. write operations). However, users can run certain tests in destructive mode (i.e. surface scan tests). Destructive tests will speed up testing because FDAT does not preserve the data on the media prior to the test beginning. Unlike non-destructive tests, any data present on the media prior to the test beginning is lost.

FDAT allows for enabling or disabling destructive tests, as well as specifying a range of destructive and non-destructive sectors on the tested drive. This is done through the configuration of the FDAT.INI.If destructive and non-destructive ranges somehow overlap, then the overlapped area is considered non-destructive. For example, if users specify both destructive and non-destructive ranges as the same, then the entire drive is tested as non-destructive.

Quick and Full erase - hard drive

The Diagnostics program offers two hard drive format utilities:

v Quick Erase Hard Drive v Full Erase Hard Drive

The Quick Erase Hard Drive provides a DOS utility that performs the following steps.

v Destroys the Master Boot Record (MBR) on the hard drive. v Destroys all copies of the FAT Table on all partitions (both the master and

backup).

v Destroys the partition table. v Provides messages that warn the user that this is a non-recoverable process.

16 Hardware Maintenance Manual

The Full Erase Hard Drive provides a DOS utility that performs the following steps.

v Performs all the steps in Quick Erase. v Provides a DOS utility that writes random data to all sectors of the hard drive. v Provide an estimate of time to completion along with a visual representation of

completion status.

v Provides messages that warn the user about non-recoverable process.

Important: Make sure that all data is backed up before using the Quick or Full Erase functions.

To select the Quick Erase or Full Erase Hard Drive utility, use the following procedure.

1. Select the UTILITY option on the toolbar and press Enter.

2. Select either the QUICK ERASE or FULL ERASE HARD DISK option and

follow the instructions.
