Hardware Issues
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 the
device 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 System p and pSeries Host Systems
Microcode changes are available from the following IBM Web site:
http://www14.software.ibm.com/webapp/set2/firmware/gjsn
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.
