Drive linking linearly concatenates objects, allowing you to create large storage objects and volumes from smaller individual pieces. For example, say you need a 1 GB volume but do not have contiguous space available of that length. Drive linking lets you link two or more objects together to form the 1 GB volume.
The types of objects that can be drive linked include disks, segments, regions, compatibility volumes, and other feature objects.
Any resizing of an existing drive link, whether to grow it or shrink it, must be coordinated with the appropriate file system operations. EVMS handles these file system operations automatically.
Because drive linking is an EVMS-specific feature that contains EVMS metadata, it is not backward compatible with other volume-management schemes.
