22.1. What is object-replace?

Occasionally, you might wish to change the configuration of a volume or storage object. For instance, you might wish to replace one of the disks in a drive-link or RAID-0 object with a newer, faster disk. As another example, you might have an EVMS volume created from a simple disk segment, and want to switch that segment for a RAID-1 region to provide extra data redundancy. Object-replace accomplishes such tasks.

Object-replace gives you the ability to swap one object for another object. The new object is added while the original object is still in place. The data is then copied from the original object to the new object. When this is complete, the original object is removed. This process can be performed while the volume is mounted and in use.
