10.Open the disk’s properties to check the target IDs. In the following figures, disks are configured as:

Disk 1: Target ID 1

Disk 2: Target ID 2

Disk 4: Target ID 1

Disk 5: Target ID 2

Disks with the same target ID are mirrored.

Disk 2

Disk 4

Disk 5

IMPORTANT: Hard disks are numbered from “0” at the OS startup according to the position they are inserted. When you increase a hard disk while the system is running, it will be given a number that is not used for any disks. However when you restart the system, the old disk numbers will not be retained and disks are re-numbered according to the hard disk position. Therefore, you need to determine which disks are mirrored based on target IDs, which are always fixed, but not on disk numbers because disk numbers may change.
