Creating and Managing Arrays and Partitions
Note:
Before you create more than one array, you must be
sure that your host OS supports multiple Logical Unit
Numbers (LUNs). Most OSs do, or can be enabled to. If
yours does not, the host sees only one array at LUN 0.
Refer to
Setting the Host System HBA to Multiple-LUN
in the
DuraStor Installation and User’s Guide.
Before you create an array, you must decide whether you want to
partition the array. You can create two types of arrays:
■
Single-partition array
—an array that stores all data in a single
partition and is accessed by a single LUN. See
Creating a Single-
Partition Array
on page 2-2
.
■
Multiple-partition array
—an array that can have one or more
partitions, with each partition assigned its own LUN. See
Creating a Multiple-Partition Array
on page 2-6
.
For more information about partitions, see
Understanding Partitions
on page 2-22
.
Creating a Single-Partition Array
You can create an array that has just one partition. Once you create
a single-partition array, you can add more partitions later. Single-
partition arrays work well in environments that need one large,
fault-tolerant storage space for data on one server. An example
would be a large database on a single server that is used only for
that application.
To create a single-partition array:
1
From the System Menu, select
Add an Array
and press
Enter
.
The Enter Array Name window appears.
2
Enter a name for the array and press
Enter
.
You can use up to 35 characters. You can include any characters
in the name, including spaces. If you do not want to name the
array, press
Enter
. You can add or change the name later.
The system asks if you want to create one partition now for the
entire array.
