OWC Gemini Thunderbolt RAID not mounting drives after restart — requires full power drain

”OWC Gemini Thunderbolt RAID not mounting drives after restart — requires full power drain: […]The enclosure itself always shows up (Thunderbolt device, HDMI output works, LEDs light), but after a restart or cold boot, the internal drives do not mount at all — they’re missing from Finder and Disk Utility. The only way to get the drives to appear is to fully unplug the enclosure’s power and wait for a complete power drain, then reconnect power and Thunderbolt.[…]”

Hard Drive Reinclosure Issues:

A. Remount the Drives and Use First Aid:

Boot into Recovery Mode, use Disk Utility, and then unmount and mount the drives. Also, use the First Aid button for each drive.

B. Toggle Off and VPNs:

Are you using a VPN here? If so, turn it off.

C. More Voltage/Wattage:

I would also recommend plugging these into a surge protector that will boost the power, potentially to its optimal use.

D. Contact the Manufacturer:

Find the “Contact Us” site of the Manufacturer. Perhaps you need to get specific drivers or update firmware for any third-party app taking part in this.

E. Unplug All Peripherals:

Unplug all peripherals from your device, except for this. Boot up and see what happens.

F: Single-Out this User:

Create a new Administrator user and see if you get this issue. If so, then it is a system-wide error. If not, then it is an issue pertaining your current user.

G. Faulty Device?:

There’s always the possibility to consider of this being a faulty device. So, if you have coverage on this, then see about getting is serviced, or replaced.
