Creating and Managing Arrays & Partitions

When you first create an array set up for multiple partitions, all of the

space on the array is designated as free space

(Figure 114).

When you create a partition, you set how large you want the partition to

be in MB

(Figure 115).

The 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, following, free space.

In Figure 115, you can expand partition 1 or you can create 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 follows (has a higher number

than) the one you want to expand. In Figure 116, 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.
