Expand / Convert an Array
Expansion and Conversion are two different operations but they often work
together. Expansion means adding disk drives to an existing array. Conversion
means changing an existing array from one RAID level to another.
FastTrak S150 SX4 and SX4000 support this feature, however SX4000 lite does
not support it.
Expansion
Expanding an array increases the array capacity without affecting data
availability. You can expand an existing array by adding one or more free disk
drives to the array using the Expand Array function.
To expand an existing array:
1.
Click on the Array
Figure 62. Start Expansion.
2.
Scroll down in Information View to show the Conversion/Expansion Wizard
and click the Start button.
With most operating systems, expanding an array will
•
require you to partition the added space with a new drive
letter. In effect, you will end up with two arrays.
•
Plan to run your expansion during off hours. This will
eliminate delayed read-write response from the array and
allow the process to go faster.
