4.16 Dynamic Logical Drive Expansion

What Is It and How Does It Work?

Before Dynamic Logical Drive Expansion, increasing the
capacity of a RAID system using traditional methods
meant backing up, re-creating and then restoring. Dynamic
Logical Drive Expansion (a new feature of firmware
version 2.11) allows users to add new SCSI hard disk
drives and expand a RAID 0, 3 or 5 Logical Drive without
powering down the system.

4.16.1 Two Modes of Dynamic Logical Drive Expansion

There are two modes of Dynamic Logical Drive Expansion:
Mode 1 and Mode 2.

Dynamic Logical Drive Expansion

Mode 1

Mode 2
