Consider the following before changing the CMS state:
To change the settings on the Data Storage Allocation, Storage Intervals, and Restore Data pages, you must set the CMS state to single-user mode. This is not required to view information.
If a user logs out while CMS is still in the single-user state, another user cannot log in for at least ten seconds.
While in single-user mode, CMS continues to collect data for all ACDs with the data collection feature enabled.
