Automatic rebuild is enabled by default on controllers, and can be configured in CIMC, but UCSM policies may be able to override that.

Enable or Disable Auto Rebuild button

Whether the rebuild process starts on the new drive automatically when a virtual drive gets degraded. This can be one of the following: Enabled—If a drive gets degraded and a new drive is plugged in, the rebuild process on the new drive starts automatically. Note    The rebuild process overwrites all existing data; therefore, make sure that the drive that is plugged in does not contain important data. Disabled—If a drive gets degraded and a new drive is plugged in, the new drive is ignored. You must manually start the rebuild process on the new drive.

Usually yes.  Have seen a few cases that required marking the replacement drive a global hotspare before the rebuild would kick in.
