not there and highly unlikely it's coming.
I was just wondering if with the latest Flare code will we be seeing the option to 'Shrink' LUNS and not just 'Expand' LUNS in Unisphere.  Provisioning 'Thin' LUNS can lead to an over provisioned capacity situation very easily, but then after performing 'house keeping' on the host we find a 2TB LUN now only has 300GB of data, so shrinking the LUN to 500GB makes sense which in turn would  stop the VNX array from constantly complaining about being over provisioned.  Does anyone know if this functionality is or will be available in Block Code: 05.32.000.5.219
