VMware vSphere APIs for Storage Awareness (VASA) is a feature that allows vSphere hosts to gain insight into the storage types backing the datastores and enables vSphere to manage storage. For example, the VASA provider that is embedded into PowerStore allows it to manage vVols.
Note the following points about the PowerStore VASA provider:
Caution: The VASA certificate is set with a one-year expiration by default, and you should periodically renew it through the vCenter Storage Providers by clicking Refresh Certificate. If the certificate is not refreshed before expiration, see KB 190731: How to renew the PowerStore VASA storage provider certificate after expiration.
Note: To use the PowerStore VASA provider across multiple vCenter Servers, there are two options: Use Enhanced Linked Mode or Share the vCenter root certificates across vCenter Servers. For more information, see PowerStore: Using vVols across multiple vCenters: How to register the PowerStore VASA provider across multiple vCenters.
