Remove storage from a vVols datastore
If a VMware Virtual Volumes (vVols) datastore has multiple FlexVol volumes, you can remove one or more of the FlexVol volumes from the vVols datastore without deleting the datastore.
About this task
A vVols datastore exists as long as at least one FlexVol volume is available on the datastore. If you want to delete a vVols datastore in a HA cluster, then you should first unmount the datastore from all hosts within the HA cluster, and then delete the residing .vsphere-HA folder manually using vCenter Server user interface. You can then delete the vVols datastore.
From the vSphere Client Home page, click Hosts and Clusters.
Right-click the vVols datastore that you want to modify, and then select NetApp ONTAP tools > Remove Storage from vVols Datastore.
The Remove Storage from vVols Datastore dialog box is displayed.
Select the FlexVol volumes that you want to remove from the vVols datastore, and click Remove.
Click OK in the confirmation dialog box.
If you select all of the FlexVol volumes, an error message is displayed, indicating that the operation will fail.
