[. . . ] (Optional) Enter a label of no more than 15 characters to identify the array. If you are creating a RAID 0 array, select the stripe size that you want the array to use. Available stripe sizes are 16, 32, and 64 KB (the default setting). Select one of the options listed under the Create Using heading to determine the method that the controller is to use to build the array. Table 1 describes typical circumstances for which each method is appropriate. CAUTION: Do not interrupt the creation of a RAID 0 array using the Migrate method. If you do, there is no way to restart the array creation or to recover the data that was on the source drive. CAUTION: Do not use the Migrate or Build methods to create an array on Microsoft® Windows® dynamic disks (volumes). These methods cause data loss in this case. Table 1 Choosing a method for creating the array RAID level 0 0 Method No Init Migrate Method is appropriate for. . . Creating a RAID 0 array when you want to preserve data on an existing drive. If you select this option, you are asked to designate the source drive. The contents of the source drive are preserved and any data on the new drive is lost. Creating a RAID 1 array when you want to preserve data on an existing drive. If you select this option, you are asked to designate the source drive. The contents of the source drive are preserved and any data on the new drive is lost. Creating a RAID 1 array on new drives, or when you want to be sure that the new array contains no existing data. This is the fastest way to create a RAID 1 array. 1 Build 1 1 Clear Quick Init NOTE: · · · · If you pause a Build or Clear process on a RAID 1 array, you can restart the process by pressing the Ctrl+R keys. A RAID 1 array created using the Quick Init option might return some data miscompares if you later run a consistency check. This is normal and is not a cause for concern. You can use drives of different sizes in a RAID 1 array. However, during a Build operation, only the smaller drive can be selected as the source drive. When migrating from single volume to a RAID 0 array, migrating from a larger drive to a smaller drive is allowed. However, the destination drive must have at least half the capacity of the source drive. Click Done. 12.

[. . . ] There are two ways to perform a rebuild: · · Shut down the system, replace the failed drive, and begin the rebuild at the next system restart. Add a hotspare to the array if necessary, and select the array for a manual rebuild. Configuring an array 7 System shutdown rebuild 1. Replace the failed drive with a new one of equal or greater capacity. At the appropriate prompt during POST, press the Ctrl+A keys or the F8 key to access the RAID Configuration Utility. [. . . ]
