To look at media resources and the allocated MRGs, use the sql query
run sql select mrg.name as mrg,d.name as resource from mediaresourcegroup mrg inner join mediaresourcegroupmember mgm on mgm.fkmediaresourcegroup=mrg.pkid inner join device d on mgm.fkdevice=d.pkid
To filter specific site
run sql select mrg.name as mrg,d.name as resource from mediaresourcegroup mrg inner join mediaresourcegroupmember mgm on mgm.fkmediaresourcegroup=mrg.pkid inner join device d on mgm.fkdevice=d.pkid where d.name like '%AD1%' or mrg.name like '%A01%'
Use this CLI command to find media resources in the default MRG (no assigned to any created MRG).
admin:run sql select d.name as resource from device as d full outer join mediaresourcegroupmember as mgm on mgm.fkdevice=d.pkid where and mgm.pkid is NULL

You look for specific device type such as MTP
admin:run sql select d.name as resource from device as d full outer join mediaresourcegroupmember as mgm on mgm.fkdevice=d.pkid where d.name like '%MTP%' and mgm.pkid is NULL
