the DNA center equipped with SSD, now if I Hard reset the Hardware through CIMC what all data we will loose?
There are multiple back-end services are running to work properly many features in the DNA appliance. In-case if the the client uninstalled any service manually then what will be procedure to install that single service?
For your first question:
Basically, hard reset flushes DIMMs and temporary data for running procedures. (hard reset flushes current unsaved data).
No matter the type of hard disk, it is not a great idea to do a hard reset for all the usual reasons, a graceful restart is a way to go ('shutdown -r now' executed from maglev CLI).
Data loss on shutdown is going to be usually minimal, the problem is more on reboot as if something was in flight that does matter, on a hard reset that won't complete and a service may fail to start.
Really you should never hard reset any system (not just DNAC) through the CIMC unless you know the OS is down or you don't care what is on the server.
Please get a full backup from DNAC before doing the hard reset if it is necessary.
And for your 2nd question:
Cisco DNA Center treats individual applications as separate from the core infrastructure. Specifically, individual packages for applications can be installed to run on Cisco DNA Center.
Packages for applications may take time to install and deploy. Therefore, install the packages during a maintenance period for your network.
Only a user with SUPER-ADMIN-ROLE permissions can perform this procedure.

Thanks for raising your concern.
If this is happening for some operational reason, BU stopped this service, then wait for sometime and I think it would get resumed in some days or you can use the 'Support' tab on the dcloud page and can raise this concern. You will get clear clarity on this service whether its being stopped temporarily or will get continued.
I would also recommend to use the 'Make a Request' Tab on the dcloud page and can mention about this enhancement, BU will think and may come up with some service to support the customers for using labs.
Hope this helps!
Thanks for your question.
Cisco DNA Center supports email notifications for both events and reports.
Emails are sent out from Cisco DNA Center using the SMTP protocol. Cisco DNA Center only supports clear text SMTP for email event notifications. If you use an email server that requires SSL/TLS support, you will not be able to receive the email event notifications.
You can configure it in the below menu:
System > Settings > External Services > Destination > Email
