Create Logical Drive Screen
To display this screen, click Create Logical Drive in the Array box (Figure 7-7) on
the ACU Main Configuration screen.
This screen allows you to select the fault-tolerance method, enable the array
accelerator (if present), and set the stripe size and logical drive size on a new logical
drive.
CAUTION: Do not use this screen to modify a pre-existing logical drive, since this
method does not preserve user data. Instead, to change the RAID level and stripe
size on a logical drive that already contains user data, click Migrate to reach the
Migrate RAID/Stripe Size screen (Figure 7-13).
