External networking (not working)


Forum|alt.badge.img+1

Nutanix external networking seems to be broken. I’m installing on a dell R730 with multiple networking cards and LOM ports. I can only get to the system via idrac. I can't seem to ssh to ahv or the cvm. I can't browse to http:// management_ip_addr either. I have no way into the system other than idrac.

Internal networking seems fine. I just can’t go external (ex. ping gateway) My thought is that there is some sort of disconnect between the virtual networks and the physical ports. For example, in VMware you need to select the right physical port for your virtual management network. I reinstalled 4 times on bare metal and don’t have any instructions wor selecting physical ports.

Community Edition?? Install the software but dont create the cluster. When installation is finished run crashcart. After that you can create the cluster.

Thanks! Yes, community edition. Can I just delete the cluster, or should I reinstall a 5th time? 😐

You can try to do a cluster destroy ;). Or else just reinstall.

When the Crashcart tool was up I saw that there was a total of 8 physical nics and 2 were connected. One was a 10GB (eth0) and the other was a 1GB (eth3). I believe eth3 is the one I want. I followed the instructions re-entered the IPs for: GW, Mask, AHV, CVM and selected done. Shortly after the Crashcart window closed I got a permissions error.
