62 Appendix B

Virtual disks can typically be rebuilt by using a global spare disk, as long as the

global hot spare is not already part of the virtual disk and has enough available

capacity. Unlike a dedicated hot spare, a global hot spare can be assigned at

anytime, even while tasks are running on virtual disks.

If there is enough space available on the global hot spare, and a disk failure

occurs, the rebuild process for the virtual disk starts automatically.
