6.2 Hot Spare Limitations

  • Hot spares protect redundant logical drives only. To protect non-redundant logical drives, set the spare activation mode of the controller to predictive activation.
  • You cannot create a hot spare from an NVMe SSD that is already part of an array.
  • You should select an NVMe SSD that is at least as big as the smallest NVMe SSD in the array that it might replace.
  • You must designate a NVMe SSD hot spare drive for an array comprised of NVMe SSD drives.
  • Changing spare type for Shared Dedicated Spare Drive from physical device is not possible. The Array level Spare Management option must be used to change the Spare Type from Dedicated to Auto-Replace when the Dedicated Spare is protecting multiple arrays. By changing the spare type from Dedicated to Auto-Replace, the shared Dedicated Spare gets unassigned, and it does not protect the selected array anymore. The user must assign the ready drives as an Auto-Replace spare to protect the selected array.
