racadm set iDRAC.NIC.DNSDomainName <iDRAC-DOMAIN.NAME>

     

  5. Verify the configuration by running the following command. 
    racadm getSysInfo

     

Host IP Address

The host IP address can be manually configured using the host's bash shell. For the settings to be persistent, the following configuration must be completed.

  1. Configure the network settings by editing the /etc/sysconfig/network-scripts/ifcfg-devicebr file. 
    DEVICE=devicebr
NAME=devicebr
TYPE=Bridge
ONBOOT=yes
BOOTPROTO=none
IPADDR=<ip address here>
NETMASK=<subnet mask here>
GATEWAY=<gateway ip address here>
DELAY=0
USERCTL=yes
NM_CONTROLLED=no

     

  2. Configure the DNS settings by editing the /etc/resolv.conf file. 
    nameserver <dnsServerIP-1>
nameserver <dnsServerIP-2>
search <domain1> <domain2>

     

  3. Restart the networking service so the changes take effect.

Setup Steps for Single Node CVP

Complete the following steps to set up single node CVP.
  1. Access the primary CVP VM via WOK.
  2. Refer to the CloudVision Configuration Guide for the Shell-Based Configuration of a Single-node.

     

Setup Steps for Multi-node CVP Cluster

Assign a role to each of the three CVP VMs (primary, secondary, or tertiary).
  • The roles may be assigned in any way, but the roles must be kept consistent throughout the installation. No two nodes may share the same role.
  • Maintain the installation order, starting with primary, secondary, and tertiary.

     

To assign the roles, complete the following steps.
  1. Print the CloudVision Worksheet. Circle the role of each appliance: one primary (P), one secondary (S), and one tertiary (T).
  2. Access the respective appliance's primary, secondary, and tertiary CVP VMs via WOK.
  3. Refer to the CloudVision Configuration Guide for the Shell-Based Configuration of Multi-Node.

Log into the CVP Web Interface

After CVP is running on the multi-node appliance cluster, enter the CVP Web Interface of the primary node via its CVP IP/Hostname with default username/password of cvpadmin/cvpadmin to set the password.

For Multi-node clusters, setting the password only has to be done on one node, and is synced to other nodes so subsequently any node can be accessed via its web interface. Refer to the CloudVision Configuration Guide for instructions on using CVP.
