I know that this has been asked before, but I cannot see a satisfactory reply. In our HUS110 setup HSNM2 works fine but HCS 7 is having trouble refreshing data from the storage array. Any task to refresh ends in failure with the message "Another management application on the network is changing the storage system configuration. (KAIC05305-E)".
I have seen a recommendation to turn off authentication, but if this means no password needed to manage the array this would not be feasible.
