An attempt was made to disable Storwize V7000 Gen1 compatibility mode. This mode must be enabled on any system that contains Storwize V7000 Gen1 enclosures alongside enclosures. The system contains such a combination, so the request to disable the mode was refused.
If you must disable Storwize V7000 Gen1 compatibility mode, remove the Storwize V7000 Gen1 enclosures from the system and run the command again.
