Logical Drive Background Activity

The Logical Drive–Background Activity tab provides information about functions that run in the background on this logical drive:

•Logical Drive Initialization

•Logical Drive Redundancy Check

Logical Drive Initialization

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 on the logical drives left behind from earlier configurations. For this reason, Initialization is recommended for all new logical drives.

Caution

When you initialize a logical drive, all the data on the logical drive will be lost. Backup any important data before you initialize a logical drive.

Initialize a Logical Drive:

1.Click the Subsystem icon in Tree View.

2.Click on the Logical Drive Summary icon.

3.Click on the icon of the logical drive you want to Initialize.

You can also start Initialization from the Subsystem icon Background Activities tab

4.Click on 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.
