ASUS GUI RAID Manager: Array Management
4-38 4.16 Dynamic Logical Drive Expansion
Mode 1 Expansion involves adding more SCSI hard disk
drives to a logical drive, which may require that the user
obtain an enclosure with more drive bays. The data will be
re-striped onto the original and newly added disks.
In the figure above, new drives are added to increase the
capacity of a 4-Gigabyte RAID 5 logical drive. The two
new drives increase the capacity to 8 Gigabytes.
