Notifications are Nasuni Edge Appliance messages. You might receive the following types of notifications:
Info: The system has performed an action, or has changed its state, in such a way that the user might be interested, but that does not require action or attention.
Warning: Something unusual has happened, but the user need not take action.
Error: Something unusual or incorrect has occurred, and the user should take notice and try to resolve the situation, if possible. Errors generate email messages to the user, if the user has set up email.
Alert: Something unusual or incorrect has occurred, and the user should take notice and try to resolve the situation, if possible, or contact Nasuni for assistance, if necessary. Alerts generate emails to the user, if the user has set up email. Examples of alert notifications are:
Software update available.
Warning: Do not attempt to restore from a virtual machine snapshot or backup.
Account issues.
Local cache issues.
Evaluation period expired.
Note: The Notifications page, and all other pages of the Nasuni Edge Appliance user interface, might look different to different users. Also, different menus and actions might be available for different users. This is because different users are assigned different permissions, based on their roles in the role-based access control system. See “Users and Groups” for details.
