Subsystem Management window. Choose the feature you want to disable from the list, as
shown in Figure 7-37, and confirm.
Figure 7-37 Disable premium feature
Keep in mind that the change happens immediately. If you use storage partitioning and
disable the premium feature, then you cannot create new partitions. However, any existing
partitions remain operational.
7.3 Saving and loading the configuration
Once your DS storage subsystem is configured and running, save this configuration in order
to be able to restore it in case of problems.
The saved configuration includes the array and logical drive configuration, the name of the
subsystem, its cache settings, and other parameters, including the storage partitioning
configuration.
The saved file can be used to restore the configuration data to the same DS storage
subsystem, or also to other DS storage subsystems in case you want to set up multiple
storage subsystems with the same configuration. To allow that action, the destination
subsystem must have the same hardware layout, number of enclosures and drives, and drive
capacities.
