You can review I/O filters available in your environment and verify that the I/O filter providers appear as expected and are active.

When you install a third-party I/O filter, a storage provider, also called VASA provider, is automatically registered for every ESXi host in the cluster. Successful auto-registration of the I/O filter storage providers triggers an event at the host level. If the storage providers fail to auto-register, the system raises alarms on the hosts.

Procedure

  1. Verify that the I/O filter storage providers appear as expected and are active.
    1. Browse to vCenter Server in the vSphere Web Client navigator.
    2. Click the Configure tab, and click Storage Providers.
    3. Review the storage providers for I/O filters.
    When the I/O filter providers are properly registered, capabilities and data services that the filters offer populate the VM Storage Policies interface.
  2. Verify that the I/O filter components are listed on your cluster and ESXi hosts.
