Linux Installation RAID 1 or 10 array result in the data from one drive (or set of drives) being compared to the other drive (or set of drives). RAID 5 arrays are immediately initialized after being created in the BIOS by writing zeroes to all array members. The user can reboot the system before this is complete in order to use the RAID 5 array immediately. Once booted to the operating system, the RAID 5 array goes into initialization mode after a delay of up to ten minutes. The advantage of this procedure is that the RAID 5 array can be used immediately, but it will not be fault tolerant until the initialization is complete. The disadvantage of this is that it takes longer for the array to become fully redundant, because it takes longer to initialize an array than it does to write zeroes to the array.

3ware Escalade ATA RAID Controller User Guide
RAID 1 or 10 array result in the data from one drive (or set of drives) being
compared to the other drive (or set of drives).
RAID 5 arrays are immediately initialized after being created in the BIOS by
writing zeroes to all array members. The user can reboot the system before
this is complete in order to use the RAID 5 array immediately. Once booted to
the operating system, the RAID 5 array goes into initialization mode after a
delay of up to ten minutes. The advantage of this procedure is that the RAID 5
array can be used immediately, but it will not be fault tolerant until the initial-
ization is complete. The disadvantage of this is that it takes longer for the
array to become fully redundant, because it takes longer to initialize an array
than it does to write zeroes to the array.
Install and run 3DM disk management utility
Refer to the
3DM Disk Management Utility
chapter. If you are using the
3ware Command Line Interface, refer to the 3ware CLI User Guide.
