Messages appear here as the unit is formatted.

When the partitioning is complete, icons for each new volume appear on your desktop. They are now ready for use.

You can now close the Macintosh Disk Utility window. Your RAID unit is ready for use.

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.

Note: When a hot spare replaces a failed drive, an event notification is generated and appears in the list of alarms in 3DM. You can also have 3DM send you an email about this. See “Managing E-mail Event Notification” on page 25.

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.

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 31.
