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:

  1. 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.
  2. Click the Operations tab in the right-hand panel and select Make Global Hotspare.
  3. 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).
  4. Click Go to create the global hotspare.

You normally create a dedicated hot spare when you create a new configuration with the Manual Configuration option (see Manual Configuration). To add a dedicated hot spare to an existing array, follow these steps:

  1. In the left panel of the MegaRAID Storage Manager window, click the icon of a disk drive that is not already assigned to a storage configuration. (A check mark appears on the disk drive icon if it is already assigned.)
  2. In the right panel, click the Operations tab and select Make Dedicated Hotspare.
  3. Select the array to which the hotspare will be dedicated from the list on the right.
  4. 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).
  5. Click Go to create the dedicated hotspare.
