I inherited this project and that thought just occurred me. The way he had it setup was that he flagged certain volumes to ignore. So rather than "is empty" I'm switching it to "is not equal to Yes."
Thanks to both of you for your answers!
As a somewhat-related followup: is there any way to change the various properties of an alert (trigger condition, reset condition, actions, etc etc) so that when I save the alert with the new settings it won't immediately re-fire for volumes/nodes that the alert was previously active for?
Or, at least, could I possibly set all the alerts to redirect to me so that when it re-fires dozens of times it doesn't spam our entire department? And then after the alerts re-fire I can switch the alert actions back to their appropriate addresses?
