The Hotspares parameter defines a list of specific physical drives to designate as hot-spare drives.


You can use the following methods to specify the physical drives:
  • 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 should 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 should be included in the current array.


Example using channel number and SCSI ID:
Hotspares = 1:12,2:14
Example using integer value:
Hotspares = 12, 13
