An administrator attempt

s to manually reclaim space on thin-provisioned VMFS6 volumes but finds that no additional space is being recovered.

Which could be causing this?

A. vSphere 6.5 does not support manual UNMAP.

B. The manual UNMAP operation has been moved to the vSphere we

b client.

C. The VASA version is use is incompatible.

D. UNMAP is automated for VMFS6.

The additional space is not recovered because UNMAP is automated for VMFS 6. To get additional space recovered using the manual reclaim process,

you need to remove UMAP from being automated for VMFS 6.
