Expansion; Figure 72: Expainsion Concept - Accusys ExaSAN A08S3-PS User Manual

4.1.2.8.3 Expansion

Expansion adds spare disks or new hard drives to an existing array. This is no need to create a
new array or stop an array; you may add new disks online while the array is in use. Expansion
can enlarge the capacity and frequency of an array. Although you may still access the array
while doing Expansion, its performance is affected considerably. You may check the progress of
Expansion in the main view.
Example:
Note
The storage capacity of a new hard drive must be no smaller than the
other disks in the array.
Note
The ExaSAN RAID Controller allows you to create a maximum of 4
arrays with 24 maximum drives in each array. This may limit the
flexibility of the Expansion feature.
Follow the steps below to select an array to expand.
1. Select the array to add additional drives to, and select the number of drives to be added. A
"+" sign appears above the drives to be added.
2. Check the Confirm box and click Expand Array.
Note
It is only the number of drives that can be chosen, not the specific
drive.
