Methods

Methods defined in this Managed Object
ConfigureVFlashResourceEx_Task, HostConfigureVFlashResource, HostConfigVFlashCache, HostGetVFlashModuleDefaultConfig, HostRemoveVFlashResource

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.
