You can use vSphere storage policies to control the datastores on which OpenStack instances are created.
Note: After you set a storage policy on an FCD volume, you cannot remove the storage policy from the volume. However, you can change the storage policy used by an unattached volume.
Prerequisites
Create the desired storage policy in vSphere. For details, see Storage Policy Based Management in the vSphere Storage document.
Procedure
Results
The specified vSphere storage policy is applied to all new OpenStack instances that are created from the flavor. The default storage policy is applied to all new instances that are created from a flavor not associated with a storage policy.
