Enable Virtual Machine Storage Policies

To use storage policies for virtual machines, you must enable them for a host or a cluster.

Prerequisites

Verify that a single host or all the hosts in a cluster, where you want to enable the policies, include the Storage Policies license.

Procedure

1	From the vSphere Web Client Home, click Rules and Profiles > VM Storage Policies.
2	Click the Enable VM Storage Policies icon ().
3	Select the vCenter Server instance. All clusters and hosts available for the selected server appear. You can see the server licensing status and whether storage policies are enabled.
4	To enable storage policies, select a host or a cluster whose status is Disabled or Unknown and click Enable.

The status of the host or cluster changes to Enabled.
