You can do
smartctl -a -l ssd /dev/sda -d cciss,1
smartctl -a -l ssd /dev/sda -d sat+cciss,1
you can count the last number then up to select the new HDD.
this will result in:
root@pve:~# smartctl -a -l ssd /dev/sda -d cciss,1
smartctl 7.1 2019-12-30 r5022 [x86_64-linux-5.4.44-2-pve] (local build)

ip link set eth0 promisc off
