Enabling Revertible Hot Spare

Does my controller support this feature? See Supported Features.

Select the Revertible Hot Spare task to copy data back from a hot spare to a physical disk.

If the physical disk in a virtual disk fails, the data on the failed disk is copied to the assigned hot spare. If you replace the failed disk with a new physical disk and if you have enabled the Revertible Hot Spare task, the data is copied from the hot spare to the new disk.

You can also use the Revertible Hot Spare task to copy data from a physical disk to the hot spare on a predictive failure event.

If Revertible Hot Spare is enabled and the physical disk is SMART-enabled, the controller firmware automatically starts copying data from the SMART-enabled disk in the virtual disk to the hot spare.

NOTE: To use the Revertible Hot Spare task, ensure that you have assigned a hot spare to the virtual disk.

NOTE: If the disk is not SMART-enabled or if the Auto Replace on Predictive Failure option is disabled, the failed disk is not replaced automatically.
