Siemens Simatic IPC647C Operating Instructions Manual page 53

If you have shut down and restarted the system without installing a functioning new hard
disk, "unused" will be displayed for the corresponding SATA port. In this case, you will need
to shut down the system again and boot with the functioning hard disk. The new hard disk is
then assigned to a SATA port and can be included in the RAID array. The "Rebuild to
another Disk" command initiates synchronization of the RAID1 system.
