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.
Steps
-
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.
