Hotfix,  With OME alerts you can ignore all alerts from a particular device by using the Ignore All Alerts from Device option available when you right-click either a device on the device tree or an alert in the Alerts portal. The Virtual Disk will be under Virtual Disk, whereas the battery one will be under Storage Enclosure or Storage Peripheral. You can find more on this on page 135 of this manual - [URL] Let me know if this helps answer your question. 
Hello , We are running OME latest version , now i selected all the triggers for email but want to switch off a couple of triggers but can not find the correct trigger . Could anybody point me to the correct trigger for : Alert message ID: 2199, Virtual disk information. The virtual disk cache policy has changed Alert message ID: 2189, Battery information. The controller write policy has been changed to Write Back., Controller 0, Battery 0 [Event Code:2189]  Many thanks.
