Summary

The spare command displays a list of hot spare drives and creates, modifies, and deletes hot spare drives.

A global hot spare can replace a failed drive from any redundant disk array.

A dedicated hot spare is assigned to one or more redundant disk arrays, and can only replace a drive that belongs to one of the assigned arrays.

A revertible hot spare can be transitioned back to spare status after it replaces a failed drive in a disk array. See transit on page 217.

The hot spare drive must be of equal or greater size than the drive it replaces.
