Some legacy storage doesn t do well with large unmap jobs so in vmfs 6 it can take up to a day to see the space reclaimed from delete actions. This seems like a communication problem though with the selected host from powercli. Configure space reclamation for a vmfs6 datastore when you create a vmfs6 datastore you can. The null value is the uuid of the datastore which can be optionally specified instead of the vmfs label in case you are writing a script that you want to future proof against future.

The first value is the block count per iteration which as spoken about in earlier posts 60 000 suffices. While the vsphere client will reflect the higher priority setting if you change it.
