Use the Initialize Disk Drive option only when you have moved a subset of disk drives that were previously part of a multi-disk drive from one storage subsystem to another. Because you did not move the entire set of disk drives, the and array information about the disk drives is incomplete.
Therefore, to erase all logical drive and array information about these disk drives and make them available again for new logical drive creation, you must these disk drives. This action erases the logical drive and array information and returns the selected disk drives to an Unassigned state, which adds new or additional unconfigured capacity to the storage subsystem. You can use this capacity to create additional logical drives.
Attention:
Possible loss of data – When you initialize a disk drive, all data on the disk drive or disk drives is lost.
Important:
Use this option only under the guidance of a representative.
