[SOLVED] How to identify the logical units associated with a particular physical drive [on windows]?

I bought several SAS drives.
Model: Seagate ST14000NM0001

These physical drives are separated into 2 logical units of 7TB each.

I want to create a "spanned volume" on windows that combines these 2 units.
How can I ensure I'm matching the units of the same drive?

In Disk Management, when opening up the properties of a disk, I see a Bus Number, Target Id, and LUN.

Here are each of them:
Disk 0: Bus Number 0, Target Id 10, LUN 0
Disk 1: Bus Number 0, Target Id 10, LUN 1
Disk 2: Bus Number 0, Target Id 12, LUN 0
Disk 3: Bus Number 0, Target Id 12, LUN 1
Disk 4: Bus Number 0, Target Id 13, LUN 0
Disk 5: Bus Number 0, Target Id 13, LUN 1
Disk 6: Bus Number 0, Target Id 14, LUN 0
Disk7: Bus Number 0, Target Id 14, LUN 1

It appears that Target Id represents each physical disk, and LUN represents each logical unit.
So to match logical units of the same drive, I look for matching Target Ids.

Is this definitely the correct way to match them?
The reason I ask this is because I have a hot-swappable plane that connects each SAS drive using two SATA connectors.
I'd like to make certain I'm not accidentally pairing by some arbitrary SATA connection.

Help greatly appreciated!

PS: The hot-swap plane came bundled with a SilverStone DS380 case.

Thanks Hotaru.
I couldn't find the serial number in the properties.
But using the following command, I could identify the serial number for the various disks:

wmic diskdrive <disk_number> get serialnumber

Where <disk_number> is the number found in Disk Management.

In my case, each pair of logical units returned the same serial number, which matched the Target Id in the disk properties as described in OP
