VNX storage utilization values do not match when comparing STM and Unisphere values.
All STM versions
EMC is researching the issue and will provide a patch for resolution.
Utilization information is not reported for LUNs with deduplication features. The information is reported as N/A. There is no correct utilization value when blocks are shared from within the LUN and across LUNs with a deduplication pool. The EMC provider does not report LUN deduplication details and without this information Storage Manager cannot report accurate storage utilization values.
