By default, the logical drive size associates the available space
in the array(s) with the current logical drive, accounting for the
Span setting and partially-used array space.
Step 9. Highlight Span and press ENTER.
Table 3.11 describes the spanning mode options.
For two arrays to be spannable, they must have the same stripe
width and must be consecutively numbered. For example, if
Array 2 contains four disk drives, you can span it only with
Array 1 and/or Array 3, and only if Arrays 1 and 3 each contain
four disk drives. If the criteria are not met, the CU ignores the
span setting for the current logical drive.
Step 10. Select Advanced Menu to open the menu for logical
drive settings.
Step 11. Set the Stripe Size by pressing ENTER and selecting a value.
Step 12. Set the Write Policy.
Step 13. Set the Read Policy.
Step 14. Set the Cache Policy.
Step 15. Press ESC to exit the Advanced Menu.
Step 16. After you define the current logical drive, select Accept and
press ENTER.
If space remains in the arrays, the next logical drive to be
configured appears. If the array space has been used, a list of
the existing logical drives appears.
Step 17. Press any key to continue, then respond to the Save prompt.
