Creating and Managing Arrays and Partitions

Managing Partitions

Using Adaptec Disk Array Administrator you can manage

partitions by

■ Viewing partition status information. See page 2-24.

■ Adding a partition. See page 2-9.

■ Expanding a partition. See page 2-27.

■ Changing a partition name. See page 2-27.

■ Changing a partition LUN. See page 2-28.

■ Deleting a partition. See page 2-29.

Understanding Partitions

When you create an array, you can choose to make the array all one

partition or set up the array for multiple partitions. With multiple

partitions, you create one very large array that makes efficient use

of your disk drives. For example, one very large RAID 5 array with

one dedicated spare uses less disk space for parity and spares than

five or six smaller RAID 5 arrays.

Once you set up an array for multiple partitions, you create each

partition by setting the partition size and assigning the partition a

LUN. You can also name each partition. We recommend assigning

names that indicate how the partition will be used. For example, if

the first partition will be used to store your customer database,

give it a name like cust data base.

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

the space on the array is designated as free space as shown in

Figure 2-1.
