CMMVC9714E The command failed because the new portset does not have an overlapping port so this action can cause a host outage. Specify a portset with one or more common ports or turn off VDisk protection to force the change.
Explanation
Mapping a new portset to a host can cause host outage without an overlapping port. The newly mapped portset must contain at least one port that is overlapping with all the old portsets.
User response
