EM Event: Warning: Database Instance - Agent Down

Question

Hello,
while upgrading plugins for the OMS 12 Bundle Patch and applying the BP on the agents, I get a lot of mails with the above subject - namely, one mail by every database instance and every listener running on the host.
Content of the mail is as follows:
Host=<hostname>
Target type=Database Instance
Target name=<database name>
Categories=Availability
Message=Agent Down
Severity=Warning
Availability status=Agent Down
Rule Name=Database Availability and Critical States,Target Availability Event Rule
Rule Owner=SYSMAN
Blackout on the host leads to the OMS not being able to do the upgrades - obviously a blacked-out agent is not able to do that. What puzzles me that in the Rule mentioned in the mail, incidents should only be created for the target type being down (i.e. for database instance when database is down, and so on) as one would expect.
I would rather not blackout all targets on a host EXCEPT the agent as this gets old with our number of hosts and dbs, does anyone know which rule is responsible for the mails and how they could be suppressed temporarily in an efficient way?

I think Jay was referring to selecting availability events by severity. So in the rule create/edit "Select Events" step you can do the following:
1. select (event) Type= Target Availability
2. Leave the radio button in the sub-section at "All events of type Target Availability"
3. select the check box next to "Severity" right below the Type field
4. When a subsequent drop down shows up for severity - select "Fatal"
5. Optionally, check the box next to "Target type" and choose "Database Instance" if your target set includes other targets - this step should not be needed.
6. Everything else should remain the same.
Essentially, the "target down" events come with "Fatal" severity and these "agent down" events come with a "Critical" severity. So this is a way to avoid getting the agent down notifications on databases (or any other targets) while getting the genuine target down notifications. Hope this helps.
