the class VirtualArrayService method getOtherSearchResults.

/**
 * Finds the virtual arrays for the initiator port with the passed
 * identifier and returns the id, name, and self link for those virtual
 * arrays. This API only supports fiber channel and iSCSI initiator ports,
 * and the passed port identifier must be the WWN or IQN of the port.
 *
 * Note that in order for an initiator to be associated with any virtual,
 * arrays it must be in an active network. The virtual arrays for the passed
 * initiator are those active virtual arrays associated with the storage
 * ports in the initiator's active network. If the initiator is not in a
 * network, an empty list is returned.
 *
 * parameter: 'initiator_port' The identifier of the initiator port.
 *
 * @param parameters The search parameters.
 * @param authorized Whether or not the caller is authorized.
 *
 * @return The search results specifying the virtual arrays for the
 *         initiator identified in the passed search parameters.
