6.3 Initializing the Array
Initializing an array clears all the data from the drives. This ensures the validity of the data and parity
stored on the array member drives.
Two features of initialization are background and parallel. Once the array is created, initialization
automatically begins in the background. While initialization is in progress, logical drives can be created
and the disks are made immediately available to the operating system at which time data can be loaded.
As array’s are created and the initialization begins, you can have up to sixty-four (64) arrays initialized in
parallel at the same time. You may also choose to stop the initialization, or pause an initialization and
then resume it at a later time. The controls for managing are displayed on the Main screen next to the
“Array_Name” after the initialization has started. If you Stop an initialization, the array will be
automatically Trusted, see note below.
The array can be initialized at a later time in which you could choose the option to Trust. This option
should only be used in environments where the user fully understands the consequences of the function.
The trust option is provided to allow immediate access to an array for testing application purposes only.
Note
A trusted array does not calculate parity across all drives and therefore there is no known state on the
drives. As data is received from the host parity is calculated as normal, but it occurs on a block basis.
There is no way to guarantee that parity has been calculated across the entire stripe. The parity data will
be inconsistent and so a drive failure within a trusted array will cause data loss. Before you use a trusted
array in a “live” environment, you must initialize it.
1
Locate and click on the <
Array_Name
> in the Array section on the Main screen you wish to initialize. This
will open the Array Information window.
2
From the Array Information window, click the
INITIALIZE
button.
3
You will be prompted to enter your password to confirm you wish to initialize the array. Type your
password and click
GO
. A confirmation message appears indicating the success of the operation, click
the
CLOSE
button.
