We have a DS4700 that is still in production. We also have a DS4700 that we have recently decomm'd. The drives are all the same size and speed and all show the same serial number.
When we've tried to replace a failed drive in the production DS4700, the amber light goes away, but the hot spare remains in use and the disk that was replaced still shows Offline as a status.
Is there an initialization step that i am missing that must be done when i move a disk between two arrays?
