When you create a partition, you set the size of the partition.
Figure 2-2 shows a single partition.

Figure 2-2 Array After Creating One Partition
Disk Array Administrator assigns each partition a unique serial
number and sequence number. It assigns sequence numbers in the
order the partitions are created, so the first partition on an array is
number 1, the second is 2, and so on. Once you create one or more
partitions on an array, you can create additional partitions in the
remaining free space, or you can expand a partition with some
limitations.
You can only expand a partition into contiguous, adjacent free
space. In Figure
additional partitions in the free space.
After you partition all of the free space, you can expand the size of
a partition only by deleting a partition that has a higher sequence
number than the one you want to expand. For example, in
Figure 2-3, you can delete Partition 3 and then expand Partition 2
to use some or all of Partition 3's space.

Caution: If you delete a partition, you also delete all data

stored in the partition. Be sure that you back up all data
before deleting a partition.
When you expand an array, you add free space at the end of the
array as shown in
