Chapter 3 Understanding Arrays, Disks and RAID Levels 31
Prior to starting a RAID level migration/transformation, make sure that the disks selected for the
destination array have sufficient capacity. RAID level migration/transformation can occur only
when the destination array has the same or larger capacity as the source array.
While the migration/transformation is taking place, data is accessible and protected to the lowest
protection of either the source RAID level or the destination RAID level.
The Transform task can also be used to expand the capacity of an array, by using OCE. It can also
be used as part of the system backup and recovery strategy through the use of the RAID1 and
To perform this process, see Section 9.6.3, Transform Arrays on page 104.
