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 disks.
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.

If you want to add additional drives to the array drive, select them from the box on the left
side of the window. It is possible to add more than one drive at a time.
If no physical drives are offered, you have to use the Hot Plug: Add Disk function first, to
add new drives. You can open the progress information window to monitor the progress of
the expansion. If you have previously limited the capacity of the array drive, you are
asked if you want to convert this free space to a new host drive.
Caution: Before starting an expansion it is absolutely necessary to back up all data on the
system. If the expansion process includes a new, unknown hard disk and there are
problems with this disk or with the cabling of this disk, then there is a risk of data
