Summary
Spare is the command used to display all hot spare drives as well as to create and delete hot spare drives.
A Global hot spare is the most generic form. A global hot spare drive can replace any drive from a pool of equal
size or less.
A dedicated hot spare is a spare drive that has been assigned specifically to one or more pools. It is used to
replace only drives that are in these assigned pools. If a drive is marked offline that was not in one of the assigned
pools, the dedicated spare will not replace that drive. This feature can used for prioritizing pools which may have
a greater need to survive disk failures.

-i <Spare Id>

-p <PD ID>
Specifies the ID of the physical drive. Requires the -a add option to
