So I start from the very beginning: I have a Supermicro X8DT3 running with ESXi 5 which is a host for a VM (old hardware, just for test purposes). Since I'm quite a noob regarding all this, I wanted to train and learn. I installed the Supermicro IPMIView software for monitoring the sensors like FANs and temperature on a local dekstop PC (Win7). I also tried to get SNMPT Traps working which caused the main problem.. I've setup all the necessarry options in the Supermicro BIOS regarding the BMC (setting the IP, gateway and subnet) and everything worked fine. Yesterday I changed the gateway in the IPMIView software from 0.0.0.0 to the same IP of the server.. since then everything is broken. Somehow this change affected the variables in the Supermicro BIOS and now i cant connect to my IPMI host. Since I'm not a native english speaker, I try to explain it with my configuration as good as possible:
Settings BEFORE everything broke: IPMI IP: 192.168.0.97 Subnet: 255.255.255.0 Gateway: 0.0.0.0 All this made in the Supermicro BIOS in the IPMI menu (the MAC was already set).
After I accidently changed the gateway to the IP adress (dont ask why, it was a long day) nothing worked. So I decided to change the gateway in the BIOS back to 0.0.0.0.. this didnt help. I cant ping the .97 IP. So I decided to change the IP this morning to 192.168.0.197 - same result. No ping, no connection. All the other settings are like before. What did I do? What may have caused this issue? I hope I could explain this issue as good as possible!
