4. Create RAID via allows you to select between the different creation methods
for RAID 0 and RAID 1. The following table gives examples of when each is
appropriate.
Notes:
l Before adding a new drive to an array, back up any data contained on the
new drive. Otherwise, all data will be lost.
l If you stop the Build or Clear process on a RAID 1 from ACU you can only
restart it from Adaptec Storage Manager - Browser Edition. (See Chapter
4 for details.)
l A RAID 1 created using the Quick Init option may return some data
miscompares if you later run a consistency check. This is normal and is
not a cause for concern.
l The ACU allows you to use drives of different sizes in a RAID 1. During a
build operation however, only the smaller drive can be selected as the
source or first drive.
l When migrating from single volume to RAID 0, migrating from a larger drive
to a smaller drive is allowed. However the destination drive must be at
least half the capacity of the source drive.
l Adaptec does not recommend that you migrate or build an array on W in-
dows dynamic disks (volumes), as it will result in data loss.
MSI Reminds You...
Do not interrupt the creation of a RAID 0 using the Migrate option. If you
do, there is no way to restart, and no way to recover the data that was on
the source drive.
5. W hen you are finished, press Done.
