Severity levels, health status alerts
You can determine how serious an alert is based its severity level. There are five system status levels levels displayed by the Systems window, the Dashboard window, and the notification area icon. The status alerts differ between individual storage systems and active/active pairs.

Alert levels for individual systems are defined in the following list, in order of increasing severity:

Warning

Critical

Disabled or Unavailable
Monitoring is disabled or is unavailable because of some other problem.
Status alert levels for active/active pairs
Alert levels for active/active pairs are defined in the following list, in order of increasing severity:
Normal
All nodes are up and running with no problems.
Warning
