Initializing a Logical Drive
Initialization is done to logical drives after they are created from a disk array.
Initialization sets all data bits in the logical drive to zero. The action is useful
because there may be residual data the logical drives left behind from earlier
configurations. For this reason, Initialization is recommended for all new logical
drives.
Initialize a Logical Drive:
1. Click the Subsystem icon in Tree View.
2. Click the Logical Drive Summary icon.
3. Click the icon of the logical drive you want to Initialize.
You can also start Initialization from the Subsystem icon Background
Activities tab
4. Click the Background Activities tab in Management View.
5. From the Background Activities dropdown menu, select Initialization .
6. To select Quick Initialization, check the box.
If you checked the box, enter a value in the Quick Initialization Size field.
This value is the size of the initialization blocks in MB.
7. If you did not select Quick Initialization, enter a hexidecimal value in the
Initialization Pattern in Hex field or use the default 00000000 value.
Caution
When you initialize a logical drive, all the data the logical drive will
be lost. Backup any important data before you initialize a logical
drive.
