# ConfigureVFlashResourceEx_Task(configureVFlashResourceEx)

Configure vFlash resource on a list of SSD disks. If the host does not have a VFFS volume, host will format the volume first and then extend the volume on the rest of the SSDs; otherwise host will extend the existing VFFS volume on the passed SSDs. Finally host will configure the vFlash resource on the VFFS volume.

It will return HostVFlashResourceConfigurationResult describing success or failure associated with each device.

Required Privileges
  Host.Config.Storage

Parameters

Name | Type | Description
--- | --- | ---
_this | ManagedObjectReference | A reference to the HostVFlashManager used to make the method call.
devicePath* | xsd:string[] | An array of device path names that identify disks. See ScsiDisk.

*Need not be set

Return Value

Type | Description

ManagedObjectReference to a Task | This method returns a Task object with which to monitor the operation. The info.result property in the Task contains HostVFlashResourceConfigurationResult describing success or failure associated with each device.

Faults

Type | Description
--- | ---
HostConfigFault | Thrown if batch operation fails on the host. Because the returned VFlashResourceConfigurationResult contains the configuration success or fault for each device, as of vSphere API 5.x, we won't throw fault when batch operation fails.
RuntimeFault | Thrown if any type of runtime fault is thrown that is not covered by the other faults; for example, a communication error.
