In addition to these inspection and maintenance responsibilities, IBM also strongly
recommends DS4000 training for staff that supports DS4000 storage configurations.
Although training is not a part of the Health Check process, DS4000 training
reduces the potential for configuration problems and contributes to the overall
health of the system.
