With this tool you can copy the disk layout from the working to the new disk.

19.23.4. Replace a disk

In case of a disk failure, you need to replace the faulty drive. Please go to Disks and make sure that the partitions on the faulty drive are set to faulty on all mdraid arrays.

Still on Disks remove the faulty partitions from all mdraid arrays.

The faulty drive is now properly removed from all mdraid arrays.

You now can shutdown the VT AIR and replace the disk with a new one. In case of a hot swap case, you can do this operation without shutting down VT AIR.

You now need to go to Copy Disk (Repair) and copy the partition table of the working disk onto the new disk. After this operation suceeded, you can go back to Disks.

You now need to add the corresponding partition on the new disk back to each mdraid array.

A resync operation will start after the adding was succesful to sync all data to the new disk.
