6.4 Assigning an Auto-Replace Hot Spare

An auto-replace hot spare is assigned to a specific array. After using an auto-replace spare to rebuild a failed logical drive, it becomes a permanent part of the array.

To assign an auto-replace hot spare to an array:

  1. In the Enterprise view, select an array on that controller.
    Note: The auto-replace option is not available, if you select an array with a non-redundant logical device when the controller's "spare activation mode" is set to "failure activation". However, when you select a physical device itself, the option is available only if one or more auto-replace spares already exist. Otherwise, you can just assign Dedicated spares in the wizard.
  2. On the ribbon, in the Physical Device group, click Spare Management.
    The Spare Management wizard opens.
  3. Select the Auto-Replace spare type, then click Next.
  4. If you selected a physical drive in the Enterprise view, select the array you want to protect with an auto-replace spare, then click Next.
  5. If you have selected an array in the Enterprise view, select the physical drive(s) you want to assign as auto-replace hot spares, then click Next. For details on SED support operations, see Spare Management. (See Hot Spare Limitations for help selecting drives.)
  6. Review the summary of auto-replace spares and protected arrays, then click Finish.
