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.
