LUN Masking,lun Mapping Zone

We've got a separate disk array. Once the server sees the stored control system, it is possible to use the disk array disk resources, but the disk array cannot be used only for one server, so he must control the host to use some disk resources. This control is divided into two parts: part of the LUN mapping, similar to the green channel, is to ensure that the server can see some of the storage resources, part of the LUN masking, similar to the cordon, is to ensure that the server can only access to its allocated storage resources, and not allocated to the server resources, Don't meddle.
