The Hotspares parameter defines a list of physical drives to use as hot-spare drives. You can specify the physical drives by using any one of the following methods:
  • The channel number and SCSI ID (for SCSI) or bus number and target ID (for SATA/SAS) of each drive. The channel number or bus number is always 1-based. The SCSI ID or target ID is always 0-based.
  • A list of integer values indicating that the nth drive must be included in the array.
  • The keyword ALL to indicate that all remaining drives attached to the controller that are not specified in previous arrays must be included in the current array.


The following example illustrates using the channel number and SCSI ID:
Hotspares = 1:12,2:14
The following example uses an integer value:
Hotspares = 12, 13
