After the DS4700 maps a LUN to the VIS, the VIS cannot detect the LUN.
Change the DS4700 default host group type to Linux.
The default host group of the DS4700 is HP-UX. The DS4700 maps the default HP-UX LUN to the VIS. However, the operation system of the VIS is Linux. Therefore, the VIS cannot detect the LUN mapped by the DS4700.
The fault occurs because the default host group type of the DS4700 is HP-UX. The fault can be removed by changing the host group type to Linux. You need to configure the host group type when Huawei VIS takes over IBM disk arrays.
