Expansion of an Array
Click the right mouse button on the array drive icon.
There are two functions that are available within this option:
•
migrate the RAID level of the selected RAID Array drive
(RAID 0
→
RAID 4 and vice versa, RAID 0
→
RAID 5 and vice versa) and/or
•
expand the capacity of the selected array drive by adding one or several new hard disk drives.
Both functions can be selected at the same time. For example, migrate from RAID 0 to RAID 5
and add a new drive. To initiate a migration or expansion with a RAID 4/5 array drive, the state
must be ready. The data on the array drive remain intact and are not affected by the expansion.
The additional capacity is introduced as a new host drive. If a logical drive fails during the
expansion, the expansion process continues until the expansion is finished. The array drive changes
into the fail state. The new capacity is available as a new host drive. Windows NT (Tool: Disk
Administrator) and Novell NetWare (“Scan for new Devices”
and then Tool: Install) allow the
online integration of new disk capacity. Depending on the RAID level the current array drive has,
selecting a different one will cause the Migration of the RAID level of the array drive. If you select
the same RAID level, the following procedure will expand the capacity of the array drive only.
