Thick provisioning is not supported for operations such as creating or cloning a VVol VM. Only thin provisioning is supported.
VASA Provider
The VASA provider enables support for VMware VVols operations.
A VASA provider is a software interface between the vSphere vCenter server and vendor storage arrays. Dell provides its
own VASA provider that enables vCenter to work with Dell storage. This VASA provider supports the VMware VASA 2.0 API
specifications.
When the VASA provider is registered, vCenter can be used to create and manage VVols on the Storage Center.
You must configure the VASA provider if you intend to use VVols in your environment.
VASA Provider Restrictions
The following restrictions apply to the VASA provider:
The Storage Manager VASA provider can be registered to only one vCenter Server.
All ESXi and vCenter Server requests to the VASA provider are mapped to a single Storage Manager user.
The VASA provider does not support user-defined storage profiles. Only default system-defined storage profiles can be used
in VM Storage Policies.
Register the VASA Provider
You can register the VASA provider on a vCenter server, and manage it from the Servers view of Storage Center.
Register the VASA provider using one of the following methods:
When initially registering a vCenter Server in the Storage Manager client, select the Register VASA Provider check box.
For a vCenter Server that is already registered in the Storage Manager client, select Edit Settings and then select the
Register VASA Provider check box.
NOTE:
After a software update, the follow error might occur:
Error registering VASA provider: Error running VMware method
[Method: RegisterVasaProvider] [Message: The VASA provider did not
respond]
Follow these steps to fix the error and register the VASA provider:
1. Open the file :msaservice\plugins\module_manager\product-metadata.json .
2. Change the VASA status to deploy.
3. Restart the Data Collector.
