Configuration

Creating a Multiple-Partition Array

This function allows the user to create multiple-partition arrays. Multiple-partition arrays work

well with very large disk drives and make the most efficient use of disk space for fault tolerance

(parity and spares). Refer to section "Understanding Partitions" for further information.

To create a multiple-partition array:

Select Add an Array from the System Menu and press Enter.
The Enter Array Name screen should now display (Figure 13).

Enter a name for the array and press Enter.
Up to 20 characters (any character, including spaces) can be used. If no name is to

be used, just press Enter (a name may be added or changed later).
The system will now ask if you want to create one partition for the entire array.

Select No to create a multiple-partition array and press Enter.
The RAID Type screen should now display (Figure 15).

Select the array type (RAID0, RAID3, RAID4, RAID5, RAID50, VOLUME, or MIRRORED)

and press Enter.

NOTE:

A RAID 10 array is created when there are more than two drives in a mirrored array.

If RAID 50 is selected as the RAID type, the Select RAID 50 Array Size screen displays

all possible configurations for the array and drive combinations. Select the desired

configuration and press Enter. Skip to Step 7.
For all other RAID types, the Number of Drives screen will display (Figure 16).

Enter the number of drives (excluding spares) to be used in the array and press Enter.
The Select Drives screen should now display (Figure 17).

Select the drives to be used for the array and press Enter.
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.
If the array is mirrored, RAID 3, RAID 4, RAID 5, or RAID 50 and there are one or more

drives left, the Number of Spares screen will display.

Enter the number of spares to be added and press Enter.
This creates dedicated spares that can only be used in this array. A dedicated spare

drive will not be available for any other use (refer to section "Managing Spares" for

further information).
