I never bump into a problem when RAID and Hot Spare are needed, I hope someone can give me enlightenment what will happen if this happened. I setup an Integrated Mirroring with 2 + 1 (hot spares) HD SAS. And let say main HD fail and the other one will automatically take control all the application, will the hot spares become the raid? so the IM will be the one from mirrored HD and Hot Spares? And the main HD contain all the important application Ses, web server, etc. What will happen to those services? Do I need to restart?
