use of com.emc.sa.service.vipr.compute.tasks.SetBootVolume in project coprhd-controller by CoprHD.

the class ComputeUtils method setHostBootVolumes.

 * @param Map of Host to bootVolume URI
 * @param boolean set to true to update the UCS service profile's san boot targets
 * @return list of hosts for which boot volume association was successfully set.
