You can execute this on one of your hosts.

# vdsClient -s 0 getStorageDomainsList
to get storage domain list, than 

# vdsClient -s 0 getStorageDomainInfo <domain UUID>
for each of them till you identify the domain you are looking for.
You can also find there the pool UUID.

Than
# vdsClient -s 0 getVmsList <pool UUID> <domain UUID>
To get the list of VMs on that storage.
