## Managed Object Description

Interface to manage IO Filters installed on the ESXi hosts and IO Filter configurations on virtual disks. IO Filters are customized filters provided by third parties to process I/Os to virtual disks. They can be used to provide data services such as flash caching and replication. This interface is only supported on vCenter server.

# InstallIoFilter_Task(installIoFilter)

Install an IO Filter on a compute resource. IO Filters can only be installed on a cluster.

Required Privileges
  Dynamic - See discussion above

Parameters

Name | Type | Description
--- | --- | ---
_this | ManagedObjectReference | A reference to the IoFilterManager used to make the method call.
vibUrl | xsd:string | The URL that points to the IO Filter VIB package.
compRes | ManagedObjectReference to a ComputeResource | The compute resource to install the IO Filter on. "compRes" must be a cluster.

Return Value

Type | Description
--- | ---
ManagedObjectReference to a Task | This method returns a Task object with which to monitor the operation. The task is set to success if the filter is installed on all the hosts in the compute resource successfully. If the task fails, first check error to see the error. If the error indicates that installation has failed on the hosts, use QueryIoFilterIssues to get the detailed errors occured during installation on each host. The dynamic privilege check ensures that the user must have Host.Config.Patch privilege for all the hosts in the compute resource.

Faults

Type | Description
--- | ---
AlreadyExists | Thrown if another VIB with the same name and vendor has been installed.
InvalidArgument | Thrown if "compRes" is a standalone host.
RuntimeFault | Thrown if any type of runtime fault is thrown that is not covered by the other faults; for example, a communication error.

# ResolveInstallationErrorsOnCluster_Task(resolveInstallationErrorsOnCluster)

Resolve the errors occured during an installation/uninstallation/upgrade operation of an IO Filter on a cluster.

Depending on the nature of the installation failure, vCenter will take the appropriate actions to resolve it. For example, retry or resume installation.

Required Privileges
  Dynamic - See discussion above

Parameters

Name | Type | Description
--- | --- | ---
_this | ManagedObjectReference | A reference to the IoFilterManager used to make the method call.
filterId | xsd:string | ID of the filter.
cluster | ManagedObjectReference to a ClusterComputeResource | The cluster.

Return Value

Type | Description
--- | ---
ManagedObjectReference to a Task | This method returns a Task object with which to monitor the operation. The task is set to success if all the errors related to the filter are resolved on the cluster. If the task fails, first check error to see the error. If the error indicates that issues persist on the cluster, use QueryIoFilterIssues to get the detailed errors on the hosts in the cluster. The dynamic privilege check will ensure that the appropriate privileges must be acquired for all the hosts in the cluster based on the remediation actions. For example, Host.Config.Maintenance privilege and Host.Config.Patch privileges must be required for upgrading a VIB.

Faults

Type | Description
--- | ---
NotFound | Thrown if the filter specified by "filterId" is not installed on the cluster.
RuntimeFault | Thrown if any type of runtime fault is thrown that is not covered by the other faults; for example, a communication error.

Type
None

# ResolveInstallationErrorsOnHost_Task(resolveInstallationErrorsOnHost)

Resolve the errors occured during an installation/uninstallation/upgrade operation of an IO Filter on a host.
