I have vcenter 5.5 and 5.5 esxi host and vnx 5400 storage. on vnx 5400 storage lun is think but virtual machine disks is thin on vcenter datastores . I will delete some virtual servers ( thin disk). I should run the unmap command for reclaim . vnx 5400 luns created as a thick. I think this should be storage thin for relaim. do I need to run unmap if storage lun is thick?
