# com.vmware.vc.vsan.HostVendorProviderRegistrationFailedEvent

## Summary

Vendor provider registration failed.

## Causes

VMware vSAN has failed to register a new vSAN storage provider.

vSAN storage providers are built-in software components that are either provided by VMware or developed by a third party using the vSphere APIs for Storage Awareness (VASA). vSAN storage providers are automatically configured and registered on each host in the vSAN cluster.

## Resolution

Make sure your storage supports third-party storage providers.
