SAS and USB Hardware Considerations
SAS and USB cables may affect drive performance. IBM cables are designed
specifically to keep the bus as free of noise as possible. Use of non-IBM cables may
adversely affect performance. If IBM service personnel analysis indicates a problem
with non-IBM cables, it may be necessary for the customer to replace them with
the appropriate IBM cables.
Microcode Updates
IBM constantly works to provide the best possible products. To make certain that
the drives work their very best, IBM occasionally releases changed microcode for
the drives. When a microcode change is developed, IBM makes it available to you
through the service organization or by electronic delivery.
For IBM Power Systems with AIX Operating Systems
Microcode changes are available from the following IBM Web site:
http://www.ibm.com/systems/support/fixcentral
For IBM Power Systems with IBM i (OS) Operating Systems
Microcode changes are available from the following IBM Web site:

Microcode can be installed by your IBM authorized service personnel or your
system administrator.
Summary
Your drive must be installed in the cleanest possible environment. Additionally,
IBM drives require high quality, data grade media and cleaning on a regular basis.
Media must also be stored and handled properly. Improper use, storage or
handling of drives or media may void your IBM warranty or service agreement
If a drive stops functioning due to a component failure during the drive warranty
or maintenance time, IBM will replace the drive unit. IBM will replace any
defective drive under the terms and conditions of the IBM warranty or service
agreement. It is our objective to work with you to identify the cause of any drive
problems and provide a solution.
