Configuring data drive(s) to rebuild

Open an SSH session using the management IP address of the controller you want to access using a PuTTY/Terminal client.
Use the admin user name and password for the admin account on the AMS Express system.
Attach the new drive(s) to the system by entering as below:
```
[admin@hseries-2 ~]$ sudo qsacli --attach_drive
    auto
```
This will automatically attach, format, partition, and rebuild all data drive(s) in the AMS Express system (which includes reconstructing the degraded volume).
Click Health > Storage tabs to view the detail about the status of the rebuild process as below.

The drive(s) being rebuilt/resynchronized will be displayed in orange (indicating a degraded state), but you could view the detailed status of the rebuild process, as shown in the green box above (information about the drive "recovering"and "rebuilding", along with the percent complete, the synchronizing status, and time remaining are included as a reference for the state of the drive rebuild/re-synch)
You may have to click the Refresh button on the upper-right hand corner of the screen to show the rebuild status (depending on your screen refresh interval).

After finishing this procedure, the Data Drive replacement process is complete.
