# Script Name: RAID Controllers and SAS-connected Expansion Chassis: Direct Attached
# Script Version: 1.0 (01/27/08)
#
#
# Script Details: builds 4 RAID 5 LUNs from 16 drives (head unit only)
# for direct attached usage
# 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]
# Adaptive Writeback Cache: enabled [optional]
# Host Cache Flushing: disabled [optional]
# Forced Read Ahead: enabled [optional]
#
