I have an old T2000 Server with a hardware Raid1 mirror. The secondary disk failed and I purchased a new one. Its hot swap so I plugged it in and when I do a #radctl command it shows that it is in SYNC status but it never gets back to optimal. I am unfamiliar with this process. What needs to be done to get the new disk to be synced properly? I waited hours to see if it would succeed but never did. Any help is greatly appreciated.
