See page 90. No Indicates whether write caching is enabled for this array. Default is Yes. See page 90. Array Keyword Array is a required keyword, indicating the start of an array definition block. The syntax is Array=, where label is an optional alphanumeric string. For example: Array=MyData Drives Keyword Drives is a required keyword, specifying the devices to use in creating the array. There is no default value. A disk drive is identified by its channel number, ID (target), and LUN, separated by colons; for example, 0:0:0 or 0:1:0. Separate multiple disk drive identifiers with commas. Prior to creating any new arrays, the ACU initializes any drives specified by the Drives keyword. If a disk drive is specified in more than one array definition block in a script, it is initialized only once. ! Caution: Any disk drive specified within the script file is initialized, which destroys any data on that disk drive. For example: Drives=0:0:0 Drives=0:0:0,0:1:0,0:2:0
