Expanding an Array

You can expand an existing array by adding physical drives to the array. The existing array can be expanded to a
maximum of 16 drives. As part of the expand array process, the add system drive option adds a new system drive using
the increased capacity rather than increasing the size of the existing system drives. The system drive's data is striped
across a larger number of physical disk drives than before the expansion operation. When the operation is complete, the
new system drive partition needs to be created and formatted according to the operating system in use. During the RAID
set expansion process, which includes re-striping data from the old (smaller) RAID set to the new (expanded) RAID set,
the controller continues to service host I/O requests.
The user must stop the partner controller before expanding an array. When this occurs, a consistency check begins if the
logical drive is in write-through cache mode. You must wait until the consistency check completes before expanding
your logical drive. When the array expansion is complete, you can bring the partner controller back online.
The following restrictions are enforced by the controller in the processing of this function:
The maximum number of disk drives in the source RAID set is 16.
The new disk drives must be added to the system while power is supplied.
The disk drives being added must not already be part of an array.
