I have a Cisco Untiy Connection cluster of two servers, one publisher and one subscriber. They are running software: 7.1.3ES43.33034-43. Yesterday at about 8:43 I lost connection to the subscriber server. I could still ping it but was unable to get to it via GUI nor SSH. I spoke to TAC yesterday and they told me to simply reboot the server. I was a little concerned about this because I don't want to cause some kind of split-brain effect. I work in a hospital and it is imperative that the voicemail system stay up. My only other option would be to do this at 4:00 am on a Sunday. Any suggestions?
