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
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.
