Creating Hot Spare Drives

Hot spares are drives that are available to automatically replace failed drives in a mirrored drive group (RAID 1 or RAID 1E). Global hot spares are available to any virtual drive on a specific controller. If you create two mirrored drive groups on the controller, the hot spares automatically replace failed drives in both drive groups. You can create one or two hot spares per controller.

Perform these steps to create a global hot spare drive:

1.	Select the Physical tab in the left panel of the MegaRAID Storage Manager main menu, and click the icon of an available online drive.

For each drive, the window displays the port number, enclosure number, slot number, drive state, drive capacity, and drive manufacturer.

2.	Select Go To > Physical Drive > Assign Global Hot Spare.

3.	Click Go to create the hot spare.

The drive state for the drive changes to global hot spare.
