Hardware responsibilities
In addition to the Health Check steps described above, regular hardware inspection
and maintenance helps to support the optimal performance of your DS4000 storage
configuration. You should periodically inspect the fibre channel components of your
DS4000 storage configuration.
The following guidelines are suggested:
v Maintain an up-to-date storage subsystem profile for your DS4000 storage
v Develop a Change Management plan. The plan should include schedules for
v Use IBM-approved fibre channel cables for all situations. Note in your

IBM System Storage DS4200 Express Storage Subsystem: Installation, User's and Maintenance Guide
Save the storage subsystem profile before performing any controller or ESM
firmware upgrades. Save the storage subsystem profile and all *.cfg files to a
server disk that will remain accessible in the event of a DS4000 storage
configuration failure.
Note: When you upgrade firmware, you must upgrade all client package
components to the same release level. For example, if you are upgrading
your controller firmware from version 5.x to version 6.x, you must also
upgrade your Storage Manager client to version 9.x or higher. If your
host system uses RDAC, upgrading controller firmware from version 5.x
to version 6.x might also require host software updates, such as RDAC
updates and HBA driver updates. Refer to the IBM DS4000 Web site for
detailed instructions.
functions are enabled:
v For all DS4000 models, Media Scan should be enabled both at the controller
level and at the LUN level.
v For all DS4000 models, the read/write cache should be enabled. In addition,
use the Storage Subsystem Profile to verify that cache is matched between
the controllers.

of a DS4000 storage configuration failure. Do not save the profile only to a LUN
in the DS4000 Storage Subsystem.
