I have a PS6100 and I was getting a message about the battery in controller 0 that had failed. I restarted, failed over to controller 1 and then replaced the battery in controller 0 but now it is not showing up under my controllers. I have restarted a few times and it just won't show up in Group Manger. I also have a "Group Operations" task from yesterday that says "restarting" and the status is "in progress" and the progress is "0%" Thanks in advance for any help...
