Considerations when management LU is set to connected external storage system port
A management LU cannot be used as an external volume.
A management LU receives commands from an application; it controls or manages the application, and stores control information from the application. An example of a management LU is a Universal Xport LU. (A CCI command device is not a management LU.)
Before performing the external volume mapping operation, perform one of the following operations on the external storage system.
Delete the management LU from the port to be connected to the Virtual Storage Platform G200, G400, G600.
Make sure that at least one LU is used for data storage and has a smaller LUN (LU number) than the management LU’s LUN. Also make sure that the data storage LU is set to the port connected to Virtual Storage Platform G200, G400, G600.
Use the security function and configure the access attribute of the management LU to prohibit read and write operations.
An external storage system that has a management LU might not be recognized by the local storage system.
