Creating a Hot Spare

You can designate an available drive as a hot spare. If a redundant unit

degrades and a hot spare the size of the degraded disk (or larger) is available,

the hot spare will automatically replace the failed drive in the unit without

user intervention.

It is a good idea to create a hot spare after you create a redundant unit.

In order to replace a failed drive, a hot spare must have the same or larger

storage capacity than the drive it is replacing, and must be of the same type

(SAS or SATA).

The Auto Rebuild policy allows automatic rebuilding to occur with available

drives that are not designated as spares. For more information, see “Setting

the Auto Rebuild Policy” on page 82.

Note: When a hot spare replaces a failed drive, an event notification is generated

and appears in the list of alarms in 3DM 2. You can also have 3DM 2 send you an

email about this. See “Managing E-mail Event Notification” on page 72.
