Initializing Disk Drives
If an installed disk does not appear in the disk selection list for creating a new array,
or if it appears grayed out, you may have to initialize it before you can use it as part
of an array. Drives attached to the controller must be initialized before they can be
used in an array.
Caution: Initializing a disk overwrites the partition table on the disk and makes any
data on the disk inaccessible. If the drive is used in an array, you may not be able to
use the array again.
Do not initialize a disk that is part of a boot array. To determine which disks are as-
sociated with a particular array, please refer to
Viewing Array Properties.
To initialize drives:
1. Turn on your computer and press Ctrl+A when prompted to access the ARC
utility.
2. From the ARC menu, select Array Confi guration Utility (ACU).
3. Select Initialize Drives.
4. Use the up and down arrow keys to highlight the disk you wish to initialize and
press Insert.
5. Repeat
Step 4 so that both drives to be initialized are selected.
6. Press Enter.
7. Read the warning message displayed in the screen.
8. Make sure that you have selected the correct disk drives to initialize. If correct,
type Y to continue.
Rebuilding Arrays
Notes: Rebuilding applies to Fault Tolerant array (RAID 1) only. If an array Build
process (or initialization) is interrupted or critical with one member missing, you
must perform a Rebuild to get the array to Optimal status. For a critical array Re-
build operation, the optimal drive is the source drive.
If no spare array exists and a hard disk drive fails, you need to create a spare
before you can rebuild an array.
To Rebuild an array:
1. From the Main Menu, select Manage Arrays. From the List of Arrays, select the
array you want to Rebuild.
2. Press Ctrl+R to Rebuild.
