Some heterogeneous storage systems (such as IBM Storwize V series, EMC DMX3/DMX4, HDS HUS VM, HDS VSP, HP P9500 or Sugon DS800-G10/DS800-G20/NetApp E series/Inspur AS1000G6/DCS3700/Dell PowerVault MD series) cannot transmit its thin LUN properties to local storage systems. Therefore, after a local storage system takes over thin LUNs from such a heterogeneous storage system, services on those thin LUNs can still run normally but those thin LUNs are presented as thick LUNs on the local storage system.
