3.5 Expanding Disk Capacity Online: Using OCE Online Capacity Expansion (OCE) allows:
• Adding disks to an array at any time to increase an array’s capacity.
• Accessing the array data while it is being redistributed.
To increase the size and organization of an array, transform the array. For more information about
transforming arrays, see Section 9.6.3, Transform Arrays on page 104.
3.6 Migrating RAID Levels Online: Using ORLM Online RAID Level Migration (ORLM) allows an array to move from one RAID level to almost
any other RAID level. This task includes migrating the array from a non-redundant RAID level to
a redundant RAID level.
