Appendix D: Using the Array Configuration Utility for DOS ● 98

Array Definition Block Keywords

The array definition block always begins with the keyword Array and ends with the keyword

End. The other required array definition keywords are Drives and Type.

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

Array=<label>

, 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

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.
