3ware 9000 Series Serial ATA RAID Controller Installation Guide
If you want to use a RAID configuration which has started 
initializing, press Esc to cancel the progress box. You can then exit 
3BM and boot to the operating system before the process of writing 
zeroes to the drives is complete. Once you have booted to the 
operating system, initialization of the RAID 5 or RAID 50 unit will 
begin after a delay of up to ten minutes. 
When initializing is done after booting to the operating system, the 
process of initializing takes longer than it does if initialization is 
done by writing zeroes to the array in the BIOS. Consequently, it 
will be a longer period of time until the performance of the unit is 
fully optimal. Data remains intact when initialization is done in the 
operating system.
For RAID 1 and RAID 10
RAID 1 and RAID 10 units are not initialized when they are created 
and are immediately available for use with full performance when 
created.
Initialization of RAID 1, RAID 10, RAID 5 with 3 or 4 disks, 
RAID 50 with 6, 8, or 9 drives, and RAID 50 with 12 drives 
configured in 3 subunits of 4 each or 4 subunits of 3 each will take 
place the first time the array is verified, either via 3BM, through 
3ware 3DM 2, or through the 3ware CLI. The steps below describe 
how to do this through the BIOS (3BM). For information about 
using 3DM 2, see 3ware 9000 Series Serial ATA RAID Controller 
User Guide
. For information about using the CLI, see 3ware 
Escalade 9000 Series Serial ATA RAID Controller CLI Guide
.
To start initialization through Verify in 3BM
1
Reboot and restart 3BM. 
2
Select the array you want to verify. (Highlight it and press 
Enter.)
3
Tab to Maintain Array and press Enter.
