# Script Assumptions: no arrays or logical drives created
# (uncomment out array deletion if needed)
# script works with either SATA or SAS configurations
#
# Global controller settings
# LUN Affinity: enabled [required]
# ALUA: enabled [required]
# Adaptive Writeback Cache: enabled [optional]
# Host Cache Flushing: disabled [optional]
# Forced Read Ahead: enabled [optional]
#
