Both .db correctly contain both firmware version of your ST20000NM007D-3DJ103 HDDs.

But model.dtb has some issues:

	Line 568: 	RX1211rp {
	Line 570: 		model = "synology_rx1217rp";   <-------- should be synology_rx1211rp
	Line 669: 	RX1211 {
	Line 671: 		model = "synology_rx1217rp";   <-------- should be synology_rx1211

fixed_model.zip
Copy this model.dtb to /etc and /etc,defaults (they should be owner=root, group=root and 0644 permissions. Then reboot and check storage manager again.

I can make these changes and will report back but I want to ask why those lines are incorrect? My external expansion unit is a rx1217rp not a rx1211rp?

I went ahead and uploaded the file model.dtb you provided. I set the owner, group, and permission correctly and verified using ls -l model.dtb and stat -c '%A %a %n' model.dtb. I then rebooted It did not fix the issue as all drives in the expansion unit still show red unverified after a reboot.

You ran syno_enable_eunit and your model.dts file contains rx1211 and rx1211rp at the end (which is where syno_enable_eunit inserts expansion units). Did you at some point run syno_enable_eunit and select rx1211 and rx1211rp?

The RS2821RP+ already supports rx1217 and rx1217rp so there is/was no need to run syno_enable_eunit.

Run syno_enable_db with the --restore option.
Remove any task schedules for syno_enable_db.
Schedule syno_hdd_db to run with the -n option and to run as root at boot-up.
Reboot.
If still no good, reboot again.

If still no good then run syno_hdd_db with the -nf options.
