4.4 Working with Spares

4.4.1 About Sparing Options

The DNS-3000 Series RAID controller supports three sparing options:
•

Distributed

A patent-pending sparing option comprised of reserved

space on each disk in an array

•

Dedicated

A spare disk assigned to a specific, redundant array

•

Global

A spare disk that is shared by multiple arrays

Spares are restored in the following order:

• Dedicated
• Distributed
• Global

Note:

When a task is in progress and the system is
shut down, the RAID driver may hang under cer-
tain circumstances. This may occur if arrays exist
and a task is in progress, but a drive letter has
not been assigned AND an OS partition has not
been created on the array. Because neither a
drive letter nor partition has been assigned, the
OS doesn’t notify the RAID driver that the system
is shutting down. If this condition occurs, the sys-
tem can be reset, the OS will start, and the RAID
process will also restart.
