HP 6 Port SATA RAID Controller - Manual (Page 6)

Configuring an array 6
The Array Properties menu appears, showing the RAID levels (types of array) that can be configured for the
selected number of drives. (For this controller, RAID 0 and RAID 1 are shown. Both of these RAID levels
require two drives.)
8. Select the RAID level that you want to create, and press the Enter key.
9. (Optional) Enter a label of no more than 15 characters to identify the array.
10. 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).
11. 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 Method Method is appropriate for…
0 No Init Creating a RAID 0 array on new drives.
0 Migrate 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.
1 Build 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.
1 Clear Creating a RAID 1 array on new drives, or when you want to be sure that the new array contains
no existing data.
1 Quick Init Creating a RAID 1 array on new drives. This is the fastest way to create a RAID 1 array.
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.
12. Click Done.
Managing arrays
With the Manage Arrays option, you can:
• View array properties
• Make an array bootable
• Delete an array
Viewing array properties
1. From the main menu of the array configuration utility, select Manage Arrays, and press the Enter key.
2. From the List of Arrays dialog box, select the array whose properties you want to view, and press the Enter
key.
The Array Properties dialog box appears, showing detailed information about the array. The physical disks
associated with the array appear here.
