Example—Hot Spare Pool

Figure 16–1 illustrates a hot spare pool that is associated with submirrors d11 and d12 in mirror d1. If a slice in either submirror were to fail, a hot spare would automatically be substituted for the failed slice. The hot spare pool itself is associated with each submirror volume, not the mirror. The hot spare pool could also be associated with other submirrors or RAID-5 volumes, if desired.

Diagram shows how hot spares can replace components of
a submirror after a component failure.
