Chapter 3
NOTE The arrays to be spanned must have sequential array numbers
and must contain the same number of physical drives.
If you select CanSpan, HP NetRAID Assistant will attempt to
span up to four arrays. Array spanning stops when:
Spanned arrays must contain the same number of drives in
each array.
10. To set the logical drive size, move the cursor to Size and press Enter. By
default, the logical drive size is set to use all available space in the array(s)
associated with the current logical drive. If you set the Span parameter to
CanSpan in Step 9, the current logical drive uses all space in the current
array, and all space in up to three subsequent arrays with the same number
of drives.
If you want to create more than one logical drive in an array, set a size
of less than the actual capacity.
If you want to span only two or three arrays, rather than the four-array
maximum, set a size that reflects the number of arrays you want to
span.
11. Choose the Advanced menu to set the following options.
Stripe size: This parameter specifies the size of the segment written to
each disk in a logical drive.
Write Policy: This parameter identifies the cache write policy. You
can set the write policy to Write-Back or Write-Through.
Read Policy: This parameter identifies the read policy for the logical
drive. You can set this parameter to Normal, Read-Ahead, or Adaptive.
Cache Policy: This parameter identifies the cache policy for the
selected logical drive.
(For definitions of the Write policy, Read policy, Cache policy, and
their options, see the "Glossary" in this guide.)
Press Esc to exit the Advanced Menu.

It has created a logical drive of the size you specify in
Step 10 below.
The next sequentially numbered array has a different
number of drives.
