Creating Hot Spares
Hot spares are disk drives that are available to automatically replace failed drives in a virtual disk. There are two kinds of hot spares: 1) dedicated hot spares, which are available one or more specified arrays, and 2) global hot spares, which are available to any array defined on the controller.
To create a global hot spare, follow these steps:
- In the left panel of the MegaRAID Storage Manager window, click the icon for any disk drive that is not already part of an array.
- Click the Operations tab in the right-hand panel and select Make Global Hotspare.
- Select With Affinity (if a disk in the enclosure fails, this hotspare will have the first priority to replace it) or No Affinity (the hotspare will not have a special priority to replace failed disks in this enclosure).
- Click Go to create the global hotspare.
