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.
