Hi,
Depending what you're after, something like this to figure out the instance
type:
- name: determine if we're on a nitro hypervisor
set_fact:
on_nitro: "{{ ansible_ec2_instance_type.startswith('t3') or
ansible_ec2_instance_type.startswith('c5') or
ansible_ec2_instance_type.startswith('m5') or
ansible_ec2_instance_type.startswith('r5') }}"
and then use a condition like:
when: on_nitro
to do the nvme-specific initialisation.
If you want to extract the actual volume id the way to go is to use
something like this:
VOL=$(nvme id-ctrl {{ disk.path }} | grep sn | awk '{print $3}'); echo
"${VOL/vol/vol-}"
where disk path is something like /dev/nvme1n1, that gives you volume id.
If you want the original letters you might have to parse it out of:
nvme id-ctrl /dev/nvme1n1 -v

kind regards
