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. Navigate to vCenter Server.
    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.
