Can you please provide below outputs (please mask the serial numbers),
show disk-groups
show disks
If the replaced drive shows as "Available" which means still its not configured as Spare drive. So suggest you to follow the below steps and configure Global Spare,
To add global spares
1. In the Pools topic, select Action > Manage Spares. The Manage Spares panel displays.
2. In the Add New Spares section, click on available disks to select them.
3. Click Add Spares. The system updates the global spares and a confirmation panel displays.
4. To close the confirmation panel, click OK.
After you configure Global Spare then only disk-group rebuild will start.
Hope this helps!
