How to check serial numbers of all drives
Install smartmontools:
apt-get -y install smartmontoolsRun this script to display the serial numbers of all NVMe disks installed in the system:
cat << \EOF | bash
for disk in $(lsblk -J -o NAME,MODEL,UUID | jq -rc '.blockdevices | map(select(.name | startswith("nvme"))) | .[] | .name'); do
serial=$(smartctl -a "/dev/${disk}" | grep Serial | cut -d: -f2- | tr -d ' ')
if [[ -z $serial ]]; then
serial="N/A"
fi
printf "Disk: %-12s Serial: %s\n" "${disk}" "${serial}"
done

How to mount additional hard drives
Install gdisk:

lsblk -J -o NAME,MODEL,UUID | jq -rc '.blockdevices | map(select(has("children") | not)) | map(select(.name | startswith("nvme"))) | .[] | .name'Add the disks in list and perform the command:
cat << \EOF | bash
set -e
FS="xfs"
DISKS=(
nvme0n1
nvme1n1
)
for DISK in ${DISKS[@]}; do
mkfs.xfs -f "/dev/${DISK}"
mkdir -p "/mnt/${DISK}"
sleep 2
UUID=$(blkid | grep $DISK | awk '{print $2}' | cut -d= -f2 | tr -d '"')
grep -q /mnt/$DISK /etc/fstab || echo "UUID=$UUID /mnt/$DISK $FS defaults,nofail,noatime,discard 0 2" >> /etc/fstab
