GetCurrentWwpnFromGenerator method of the Msvm_VirtualSystemManagementService class

Provides the ability to preview the current World Wide Port Name (WWPN) without the WWPN being reserved. The WWPN is generated from within the pre-configured range defined by the MinimumWWPNAddress and MaximumWWPNAddress properties of the Msvm_VirtualSystemManagementServiceSettingData class. If the range as defined by these properties is exhausted, then the generated WWPN will have the invalid entry of "0000000000000000" and the return value will indicate success (0).

Syntax
