Creating and Managing
Arrays and Partitions
Using the OCP, you can perform the following array-related
functions:
■Create arrays (see page 2-1).
■Manage arrays (see page 2-9).
■Manage partitions (see page 2-21).
Creating Arrays
You can create an array at any time. Table 2-1 describes the disk
drive requirements for each RAID level.

2-2
Creating and Managing Arrays and Partitions
Note: Before you create more than one array, you must be
sure that your host’s operating system (OS) supports
multiple Logical Unit Numbers (LUNs). Most operating
systems (OSs) support multiple LUNs, 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, 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.
Warning: We strongly recommend that you regularly and
consistently back up your data so that it may be recovered
in the event of a failure that’s not protected by a fault-
tolerant array.
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.
1Press Menu, choose Controller Menu, then press Enter.
2Choose the desired controller, then press Enter.
3Choose Array Menu, then press Enter.
4Choose Add an Array, then press Enter.

2-3
Creating and Managing Arrays and Partitions
5Enter a name for the array.
You can enter up to 27 characters (A-Z and 0-9), one at a time.
Use ↑and ↓to choose a character and then press Enter. Repeat
until the name is complete, then press Enter.
Note: If you do not want to name the array, skip this step by
pressing Enter. You can add or change the name later. The
array will be given the name A1 as a default to identify it.
The names will increment by one value for each new
unnamed array (A2, A3...).
The system asks if you want to create one partition now for the
entire array.
Note: If you want to create a multiple-partition array, see
Creating a Multiple-Partition Array on page 2-6.
6Choose Yto create a single-partition array, then press Enter.
7Choose the LUN for the array, then press Enter. (Choose any
number from 0-63.)
The system warns you about the LUN for Unix and Macintosh
OSs. (See the Note on page 2-2 for detailed information.) Press
Enter and the system asks if you want to be warned again. Select
No to avoid receiving this warning again, otherwise select Yes to
be warned the next time you create a partition.
8Choose the RAID level, then press Enter. (You can choose from
RAID 0, RAID 3, RAID 4, RAID 5, RAID 50, VOLUME, or
MIRRORED.)
Note: A RAID 10 array is automatically created when there
are more than two disk drives in a mirrored array.
■If you selected RAID 50 as the array type, the Pick RAID 50
Array Size screen appears.
Choose the configuration you want, then press Enter.
■If you chose any array type other than RAID 50, the Number
of Drives screen appears.

2-4
Creating and Managing Arrays and Partitions
9Choose the number of disk drives in the array, excluding spares,
then press Enter.
The Select Drives screen appears.
If you are using active-active mode, the Select Drives menu
includes all available disk drives (those that are not members of
an array and are not assigned as dedicated or pool spares) on
both controllers. It displays the following information for each
disk drive:
– Channel number
– SCSI ID number
– Disk drive capacity
– Disk drive manufacturer
– Disk drive model number
– Disk drive firmware revision
10 Choose a disk drive to use in the array, then press Enter. Repeat
until all the disk drives you want are selected.
11 After all the disk drives are selected, press Enter.
If the array is mirrored, RAID 3, RAID 4, RAID 5, or RAID 50 and
you have one or more disk drives left, the Number of Spares
screen appears.
If you are creating a different type of array, skip to Step 15.
12 Choose the number of spares you want to add, then press Enter.
This creates dedicated spares that can only be used by this array.
A dedicated spare disk drive is not available for any other use.
For more information, see Chapter 4, Managing Spares.
If you do not want a spare, choose 0.
13 Choose a disk drive to use as a dedicated spare, then press
Enter. Repeat, if you are using multiple dedicated spares.
Only available disk drives (those that are not members of an
array or assigned as dedicated or pool spares) display. You can
delete a dedicated spare from the array at any time. For more
information, see Deleting a Dedicated Spare on page 4-3.

2-5
Creating and Managing Arrays and Partitions
If the array you are creating is a RAID 3, RAID 4, RAID 5, or
RAID 50, the Chunk Size screen appears.
If you are creating a different type of array, skip to Step 15.
14 Choose the chunk size, then press Enter.
Chunk size is the amount of contiguous data that is written to an
array member. To determine the appropriate chunk size, refer to
your OS’s documentation. For example, the default chunk size
for Windows NT®and many other OSs is 64 KB. If you are using
the array for a database with very small records, you may want
to use a smaller chunk size.
The system asks you to confirm that you want to create an array.
15 Choose Y, then press Enter.
A message notifies you that the array is being created and shows
the progress of the initialization process. The array initialization
process can take from several minutes to several hours,
depending on the array type (volume, RAID 0, and RAID 1 are
the fastest), array size, disk drive speed, and other processes
running on the controller.
16 Press Esc to return to the System menu and perform other
functions while the initialization continues.
Checking the Progress of the Array Initialization
You can check the progress of the array initialization at any time.
1From the System menu, choose Array Menu, then press Enter.
The status of the initialization appears in the list of arrays.
2Press Enter.
3Use ↑and ↓to cycle through the status information that
appears.
If you need to change the disk drives or change some other array
configuration, you can stop the array initialization process. See
Stopping the Array Initialization Process on page 2-12.

2-6
Creating and Managing Arrays and Partitions
Note: Most OSs, such as Windows NT 4.0, require you to
reboot the host system to see the new array. NetWare v3.12
and later can recognize new devices by typing the
command SCAN FOR NEW DEVICES at the console
prompt. Other OSs might have similar features.
Creating a Multiple-Partition Array
You can create an array that has more than one partition.
Note: Once you create a multiple-partition array, you must
create at least one partition before you can use the array.
See Adding a Partition on page 2-9.
Multiple-partition arrays work well when you have very large disk
drives and you want to make the most efficient use of disk space
for fault tolerance (parity and spares).
1Press Menu, choose Controller Menu, then press Enter.
2Choose the desired controller, then press Enter.
3Choose Array Menu, then press Enter.
4Choose Add an Array, then press Enter.
5Enter a name for the array. See Step 5 on page 2-3 for detailed
instructions.
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.
Note: If you want to create a single-partition array, see
Creating a Single-Partition Array on page 2-2.
6Choose N(No) to create a multiple-partition array, then press
Enter.

2-7
Creating and Managing Arrays and Partitions
7Choose the RAID level, then press Enter. (You can choose from
RAID 0, RAID 3, RAID 4, RAID 5, RAID 50, VOLUME, or
MIRRORED.
Note: A RAID 10 array is automatically created when there
are more than two disk drives in a mirrored array.
■If you selected RAID 50 as the array type, the Pick RAID 50
Array Size screen appears.
Choose the configuration you want, press Enter, then skip to
Step 10.
■If you selected any array type other than RAID 50, the
Number of Drives screen appears.
8Enter the number of disk drives in the array, excluding spares,
then press Enter.
The Select Drives screen is displayed. See Step 9 on page 2-4 for
more details.
9Choose a disk drive to use in the array, then press Enter. Repeat
until all the disk drives you want are selected.
If the array is mirrored, RAID 3, RAID 4, RAID 5, or RAID 50
and you have one or more disk drives left, the Number of Spares
screen appears.
If you are creating another type of array, skip to Step 13.
10 Choose the number of spares you want to add, then press Enter.
This creates dedicated spares that can only be used by this array.
A dedicated spare disk drive is not available for any other use.
For more information, see Chapter 4, Managing Spares.
If you do not want a spare, enter 0.
