Configuration

If no spare is desired, simply enter 0.
The Select Drives screen should now display (Figure 17).

Select the drive to be used as a dedicated spare and press Enter.

NOTES:

Only available drives (drives that aren't members of an array and are not

assigned as dedicated or pool spares) will be displayed. A drive is

selected by highlighting it and then pressing Enter. Each selected drive

turns gray in the drive list. To skip a drive, use the é or ê key.
A dedicated spare can be deleted from the array at any time (refer to

section "Deleting a Dedicated Spare" for further information).

If the array created is RAID 3, RAID 4, RAID 5, or RAID 50, the Chunk Size screen will

display (Figure 15).

Select the chunk size and press Enter.
The chunk size is the amount of contiguous data that is written to an array member

before moving to the next member of the array. To determine the appropriate chunk

size, refer to the operating system's documentation (for example, the default chunk

size for Windows NT and many other operating systems is 64KB.
The system will now confirm your request to create the array.

10.

Select the desired option and press Enter.
Offline Initialization -

Using this option means the user must wait for the

array initialization process to finish before using the

array. It uses the zero method to create the array,

which is faster than the verify method.

Online Initialization -

Using this option means the user may use the array

immediately after creating it, while the array initializa-

tion process runs. It uses the verify method to create

the array, which takes longer than the zero method.

The system will now confirm your request to create the array.

11.

Select Yes and press Enter.
A message will notify you that the array is being created and will show the progress

of the initialization process. The array initialization process takes from several minutes

to more than an hour depending on the array type (RAID 0, RAID 1, and Volume are

the quickest), array size, drive speed, and other processes running the controller.
Press Esc to return to the Disk Array Administrator menus and perform other functions.

To check the progress of the array initialization, select Array Menu from the System

Menu. The status of the initialization will display in the list of arrays.
The array initialization process can be stopped (refer to section "Stopping the Array

Initialization Process" for further information).
