4-38 Configuring Your ServerNOTES: Before adding a new drive to an array, back up any data containedon the new drive. Otherwise, all data will be lost. If you stop the Build or Clear process on a RAID1 from ACU, youcan only restart it from Adaptec Storage Manager - BrowserEdition. (See Chapter 6 for details.) A RAID1 created using the Quick Init option may return some datamiscompares if you later run a consistency check. This is normaland is not a cause for concern. The ACU allows you to use drives of different sizes in a RAID1.During a build operation however, only the smaller drive can beselected as the source or first drive. Adaptec does not recommend that you build an array on Windowsdynamic disks (volumes), as it will result in data loss.5. Select a source drive from the Select Source Drive list box and press Enter.6. When you are finished, press Done.
