Excellent, the `dmesg` output is very helpful... Here are the commands to run as **root**:

1.  **Remove the incorrect device entry for `sdb`:**
    ```bash
    echo 1 > /sys/block/sdb/device/delete
    ```

2.  **Rescan the SCSI hosts:**
    ```bash
    echo "- - -" > /sys/class/scsi_host/host0/scan
    echo "- - -" > /sys/class/scsi_host/host1/scan
    echo "- - -" > /sys/class/scsi_host/host2/scan
    ```

3.  **Verify the result:**
    ```bash
    lsblk
    ```
