Strategy for replacing a hard disk drive
Always try to run a low-level format before replacing a hard
disk drive.
Attention: The drive startup sequence in the computer
you are servicing may have been changed. Be extremely
careful during write operations such as copying, saving, or
formatting. If you select an incorrect drive, data or
programs can be overwritten.
How to use error messages
Use the error codes displayed on the screen to diagnose
failures. If more than one error code is displayed, begin the
diagnosis with the first error code. Whatever causes the
first error code may also cause false error codes. If no
error code is displayed, see whether the error symptom is
listed in the Symptom-to-FRU Index for the computer you
are servicing.
Strategy for replacing FRUs for CTO,
CMV, and GAV
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)
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.)
