Once the hot-spare rebuilds, it is the active member of the array. Any new disks introduced into the system would need to be manually assigned as the new hot-spare.
Hi, I setup a R510 with raid 5 with 2 hot spares. Let's say one of the drive fail and the HS kick in then I replaced the bad HD. What happen to the drive that is originally setup as a hot spare? Does it reset back as a hot spare or do I need to reconfigure and make it as the default HS again?  original: 0 - active 1 - active 2 - active 3 - active 4 - active 5 - HS 6 - HS ++++++++ after HD failure; 0 - active 1 - active 2 - active 3 - active 4 - bad 5 - active (rebuild) 6 - HS +++++ after HD has been replaced; 0 - active 1 - active 2 - active 3 - active 4 - ? (does this become the active drive again?) 5 - ? ( does this become HS again? ) 6 - HS  Thanks
