Thank you for your reply. Disable and Enable the alarm seems to change something.
I took a closer look to the users manual and I saw that "Alarm Present YES" meens that there is an alarm which is indicating problems. But I don't hear any alarm. As far as I know I didn't silenced the alarm, too. I also rebootet the server without any changes.
So my questions:
1. Does "Alarm Present" means that there is a sound / error?
2. Is there a way to play a test alarm? I remember that there was a function in an older release of the RAID Manager
3. It is normal that the RAID Web Management Console is slow? When I make an action like right click on the controller or refreshing status I always must wait about 30 seconds before I can see any reaction.
