Explain what happens

I have 3 identical SATA SSDs (free from MicroCenter) connected via 3 USB-SATA adapters (same model of adapter). One of them is the boot drive, and the other two are merged via LVM into a single volume. The LVM volumes show up, but only the boot drive shows up, and the other drives are "Multipathed devices" under the boot drive.

  1. Buy multiple SATA HDD/SDDs
  2. Use multiple USB-SATA adapters of the same model
  3. View in storage

I have exactly the same issue with 3 Crucial NVME connected using the Terramaster Hybrid. The three drives are actually the same model and are correctly displayed on lsblk. But on cockpit they are displayed as a single multipath device.
