OpenManage Integration for VMware vCenter Version 5.0 Installation Guide

Configure OMIVV appliance with two network adapters

To manage the Dell EMC servers in your vSphere environment, OMIVV requires access to both the vSphere network (vCenter and ESXi management network) and out-of-band network (iDRAC, CMC, and OME-Modular). If vSphere network and out-of-band network are maintained as separate isolated network in your environment, OMIVV requires access for both the networks. In this case, OMIVV appliance must be configured with two network adapters. If the out-of-band network can be accessed using the vSphere network then, do not configure two network adapters for the OMIVV appliance.

1. Shut down the OMIVV appliance.
2. Edit the VM settings using the vSphere Client (HTML-5) and add the additional Network adapter. To edit the VM settings, right-click VM, and then click Edit Settings.
3. Click ADD NEW DEVICE, select Network Adapter.
   
   1. Select the appropriate network for the network adapter, and then select the Connect At Power On check box.
   2. Select the E1000 adapter type from the drop-down menu. OMIVV supports only E1000 type of network adapter.
      
4. Power on the VM. Log in as an administrator (the default user name is Admin), and then press Enter.
5. On the OpenManage Integration for VMware vCenter Virtual Appliance Setup utility, select Network Configuration.
   The Network Connections page displays two NICs.
   
   WARNING Do not use "+" to add any new network interface. It is mandatory to use the vSphere Edit Settings to add a network adapter.
6. Select the NIC that you want to configure and click .
7. To identify the correct NIC, use the MAC ID displayed on the Ethernet tab, and then compare it against the MAC ID displayed in the vSphere Client (HTML-5).
   Ensure that you do not change the default MAC address that is listed in the Ethernet tab.
8. Click the General tab and select the Automatically connect to this network when it is available check box.
9. Click the IPv4 Settings tab and do the following:
   
   1. Select Manual or Automatic (DHCP) from the Method drop-down list.
   2. If you select the Manual method, click Add, and then enter the valid IP address, Netmask (in the CIDR format), and gateway details. It is recommended to use the static IP in case if you want to control over the priority of the DNS servers (primary and secondary DNS entries).
      Typically, vSphere elements of data center such as vCenter and ESXi hosts are managed using hostname or FQDN. iDRAC, CMC, and OME-Modular are managed using IP addresses. In this case, Dell EMC recommends you to configure the DNS settings only for the vSphere network.
      If both vSphere network and iDRAC management network are managed by using hostname or FQDN, DNS server must be configured in such a manner that it resolves the hostname or FQDN for both the networks. For more information, see the CentOS documentation.

      NOTE The last configured DNS server becomes the primary DNS irrespective of which network the DNS is configured for.
   3. Enter the DNS server IP and domains to be searched for in the DNS Servers and Search Domains boxes respectively.
   4. Select the Require IPV4 addressing for this connection to complete check box and click SAVE.
   5. If you do not want to use this network as the default network (gateway), click Routes, and then select the Use this connection only for resources on its network check box.
      NOTE Adding multiple networks as default gateways may result in network issues and OMIVV functions may get affected.
   6. If you want to reach to any external network using the known gateways, click Add on the same page, and then add the network IP address, netmask (in the CIDR format), and gateway details.
      

      Typically, the network that you have configured as the default gateway does not require any manual route configuration because the gateway is capable of providing the reachability. However, for networks where default gateway is not configured (the Use this connection only for resources on its network check box is selected), a manual route configuration may be required. Because the default gateway is not configured for this network to reach external networks, manual routing configurations are required.

      NOTE Incorrect routing configuration may abruptly stop the network interface from responding. Ensure to configure the routing entries appropriately.
   7. Click OK.
10. Click Save . To configure another NIC, repeat the tasks 6–10.
11. Go to the OpenManage Integration for VMware vCenter Virtual Appliance Setup utility, click Reboot Appliance. The network configuration is complete only after restarting the OMIVV appliance.
    NOTE

    After the appliance is successfully restarted, the NICs start working as configured. The status of NICs can be viewed by logging in as readonly user and running the following commands: ifconfig, ping, and route -n.
