Raid 1 physical disk removed

Hi, i have 1 hard drive failure in my raid 1 configuration on Dell r730. I made a mistake not hot swapping the bad drive. I shutdwown the server and replace the drive. When i went to F2 device setup-, virtual disk i see that the drive condition was “removed “ and degraded. The new drive in physical disk is showing ready or online.  I made the physicql disk as global hot spare but i dont see the raid1 getting rebuild. What am i missing here. Thanks in advance.
