Introduction
Table 1-6 lists valid free_space specifiers.
Note: When specifying freespace during an array create
volume operation, you must explicitly specify the SCSI
device’s channel, device ID, and logical unit number. You
cannot use any default values for the SCSI device. In
addition, you must also specify the size of the freespace(s).
container
A controller currently supports 24 visible arrays. A visible array is
an array that is visible to the operating system and users. Visible
arrays are identified with array IDs 0 through 23.
Array IDs 24 through 63 are reserved for hidden arrays. A hidden
array is an array that is not visible to the operating system and can
only be used by other arrays. (However, the array list
command displays hidden arrays.)
The Parameters section uses the following syntax to specify an
array:
{array}
This syntax specifies the ID number (0 to 63 inclusive) of the array.
A controller assigns a unique ID to each of its arrays when you
create it.
