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.

Array definition keywords and descriptions are listed in this table.
Array Keyword
Array is a required keyword, indicating the start of an array definition block. The syntax is

Drives Keyword
Drives is a required keyword, specifying the devices to use in creating the array. There is no

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.
