How to specify/query device patch with Swordfish

Hello,

We are evaluating Swordfish for our use-case to implement storage pools.
I spend sometime reading Swordfish specification and it is not clear how to use device path e.g block device path.

I get that we can pass drives in the payload which we want to add to StoragePool
e.g
"Drives": [
{"odata.id": "/redfish/v1/Chassis/1/Drives/0TH8N20R"}
]

Is there also a way to specify block device path for this drive, or the application needs to use drive serial number to lookup block device.

Similarly is there is way to specify Volume's block device path when we do GET on Volume endpoint.
e.g

GET on
/redfish/v1/storage/storage_pools/ac23b784-2dff-43bc-9642-744e9132bb3b/allocated_volumes/eaa00e19-cf5d-486e-98d8-cc8a08a541f4
can also return 
/dev/vg1/vol1

Thanks
