Unable to change to static management IP in DCUI

  • 1.  Unable to change to static management IP in DCUI

    Posted 06-26-2020 02:51 PM
    First - Thanks so much for this event.  I'm a HomeLab Noob and I just bought my first HomeLab server. (Lenovo ThinkSystem SE350) This is a VMware 6.7U3 supported compatible system. I installed 6.7U3 and in the DCUI I tried to changed the management network from DHCP to Static, but then it fails the management network test. There are two adapters that are in a connected status (vmnic2 and vusb0)  I have tried both of them as the designated adapter.  I am trying to assigning a static IP from my router/switch that is connected to the internet. The gateway for my network is 192.168.1.1.  I have tried so many ways to make this work so I'm turning to you for help.

    Although the following is not my preferred method, I have been successful in browsing to the ESXi host only when I use a DHCP management IP. I figure this IP comes from ESXi.  I then connect directly from my laptop to the server (vmnic2). The laptop likewise picks up a DHCP address from ESXi so I have connectivity between my laptop and the ESXi host and can use the browser to manage it.  I am also able to have internet connectivity by using the wifi on my laptop.  The ESXi server also has access to the Internet by running another cable from the router/switch to the vusb0 interface on the server where it picks up an IP from 192.168.1.1.

    Many thanks

    Hi Aaron,

    It sounds like the network on the ESX host is not set up correctly to accommodate the vCenter Server. It's highly possible that you may just have to tweak VSS in the ESXi host. How many NICs does the ESXi host have? You said just one correct?

    While you're connected directly to the ESXi host, see if you're able to "muck" around with the networking configuration ensuring https://docs.vmware.com/en/VMware-vSphere/6.7/com.vmware.vsphere.networking.doc/GUID-B57FBE96-21EA-401C-BAA6-BDE88108E4BB.html is referred to.

    Also, it would be good to definitely look at the logs. Refer to Location of vCenter Server log files (1021804) for guidance as well.

    Best of Luck!

    Thank you Marvin.  I'm still new to ESXi but is it reasonable to think that a tested VMware compatible system would not have this kind of trouble out of the gate?  I've attached a pic of the network interfaces for the system and what ESXi sees.  I'm guessing that if I populate the SFP+ and SFP slots then vmnic0 and vmnic1 will become available and hopefully solve my problems. I can get some copper transceivers and see what happens.

    I wonder if I attach the antennas to the system if that will make another vmnic available.
