As per the upstream document, there are the following ways to deploy OSD's using advanced service specifications. 1.Rotational ============ If rotational =1 then OSD will be configured with SSD's/NVME's.If rotational=0 then the configuration will happen with HDD's.

For example: 1.lsblk -o NAME,FSTYPE,LABEL,MOUNTPOINT,SIZE,MODEL 2.smartctl -i /dev/sdb From the above two commands, we can get the model name. The convention is different. In this case, we have to inform to the customers that use "ceph orch device ls --wide" command to get the details. This information is provided by integration with libstoragemgmt. By default, this integration is disabled. To enable customer need to execute "ceph config set mgr mgr/cephadm/device_enhanced_scan true" command.
