This is a great opportunity to build out your Nutanix skill set at no cost.
Yesterday I faced an issue which took more 2-3 hour to get sorted. I had old Nutanix Block on which I need to do the foundation when I started the foundation using Nutanix Foundation VM and got error foundation process failed with error “ Unable to set IPMI IPs)
I tried to set IPMI IP on the Nutanix Nodes manually, but strange thing even after setting up IPMI IPs I was unable to ping the IPMI interface. I tried on Shared/ dedicated IPMI Port but failed.
The hardware I was using was old Nutanix Block from G4 Generation, and there was no other options in IPMI Menu in System Setup to modify except IP Address
I tried to login Hypervisor , but failed as I don’t have IP root password.
Moving forward, I got an idea make one bootable using download IPMItool from SuperMicro Website, boot the nodes from USB Drive.
When I run the IPMICFG tool and get the current VLAN Status, VLAN ID was ON on the IPMI interface. I turned off the VLAN ID.
IPMICFG -vlan off
Incase if you have access on the hypervisor IPMItool can be used to trun-off the VLAN ID, using below command to turn off VLAN Id from ESXi Host.
/ipmitool lan set 1 vlan ID off
Once the VLAN off, I am able to access IPMI ports and proceed with foundation.
AHV use Open VSwitch(OVS) to connect the CVM, Hypervisor and gest Virtual machines to each other and to physical network.
Open VSwitch is an opensource software switch implementation in the Linux Kernel. OVS acts like a Layer-2 switch which means its maintain the MAC Address table. Host, VMs connect to Virtual Ports on the switch.OVS support common switch features like VLAN Tagging, Load Balancing and link Aggregation Control Protocol (LACP). Each AHV Host server maintain and OVS instance and all OVS instance combine to form a single logical switch.
Bridges act as virtual switch to manage traffic between physical and virtual network interfaces. By default AHV configuration includes an OVS called Br0 / Br0-up and a native Linux Bridge call Virbr0. The virbr0 Linux bridge is responsible for management and storage communication between CVM and AHV host. All the other traffic (storage, host, VM) flows through br0 OVS bridge.
Ports are logical entity created in bridge that represent connectivity to virtual switch.
Bonded ports aggregate the physical interfaces on the AHV host. By default, the system creates a bond named br0-up /Br0 having all physical interfaces.
OVS bonds supports multiple load-balancing modes, including active-backup, balance-slb, and balance-tcp.
Today I have faced the strange issue, I tried to add new host to vcenter but unable to add to check the VCenter services I tried to login to Vcenter appliance Management UI but unable to login.
I tried to reset the Vcenter Appliance root passowrd but didn’t work. After troubleshoting I found the solution. Applmgmt Services was not running which was not allowing me login to management Console.
So Check the services status from Shell , open VCenter Appliance Console / SSH.
Access à Shell
#service-control –start applmgmt
Once Services started , I am able to login to console & able to add ESXi host to VCenter.
As we all know VMware WorkStation is a great solution for testing /home lab activities. Lots of guys ask me how to deploy VMware VCenter Appliance deploy in VMware Workstation as using VCenter Installer it looks for ESXi host to deploy the VCenter Appliance. So below is the procedure you can follow to deploy VCenter Server on VMware Workstation.
Download the VCenter Appliance ISO
Extract / Mount ISO
Browse to folder VSA and double click on OVA file, wizard will be started to import the OVA to VMware Workstation.
Accept the License Agreement and click Next
Specify the Virtual Machine name & location and click Next
Specify the Deployment Type and click Next
Specify the Network Configuration
Host network Family: IPV4 or IPV6
Host Network mode : Static / Dynamic
Host IP Address:
Host network Profex / Subnet
DNS Server IP
Virtual machine DNS Name
Once provide the information Click next.
Once VCenter Appliance will be deployed. Logged into Virtual machines
Set the VCenter Appliance IP and access the Virtual Machines Management using any explorer
https:// Virtual Appliance IP:5480
Now the Stage 2, will be started. Click Setup to proceed.
Click Next start the Stage 2
Provide the NTP information, Enable SSH Access incase if you want to configure VCenter Sever HA.
As I am planning to configure VCenter HA, hence enabling SSH Access. Click Next to continue.
Select the desire SSO Configuration, as I am going to setup the new SSO Domain. So I am providing the SSO domain name & Password for the Administrator. Click Next to continue.
Select the CEP option you desire and click next.
Confirm the Summary information and click finish to start the STAGE 2 Configuration. Please note that once you click Next you can’t stop the process.
Process will take upto 10-15 mins to finish the deployment.
As all we know VMWare has release the VSphere 7.0. In this article I will show how to upgrade VCenter Appliance 6.7 to 7.0.
Download VCenter Server Appliance from VMware Website. And mount the ISO. Browse to vcsa-ui-installer on Mounted Media and run installer.exe
Note: Before starting the upgrade, make sure DNS record and NTP is working fine. VCenter Appliance upgrade process will deploy the new VCenter appliance and copy the configuration and data from old appliance to newly deployed appliance. This means temporary you should the enough resources to accommodate the new VM.
Click Upgrade to start the Wizard.
Click Next to continue
Accept the license agreement and click Next
Connect the VCenter appliance
Provide the ESXi Server where you want to deploy the new VCenter VM.
Provide the New VCenter VM name & provide the appliance Root Password.
Select deployment size and click next.
Select the datastore, incase if you want to save the disk as thin format select enable thin disk mode.
Provide the network information and temporary IP.
Review the configuration and click Finish to start the deployment.
In this Stage VM is already deployed, once deployment finished you can continue to start the Stage 2. In stage 2, VM will copy the data from old appliance and configure the new appliance. Click Continue
Click the next to start the wizard.
Select the upgrade data and click next.
Select the desire CEP option and click next.
Review the configuration and click Finish to start the process.
Accept the Warning, saying source VM will be shut down when new VM get the network configuration.
Whole process takes approx. 15-20 Min to finished.
Upgrade finished, Click Close to close the installation wizard.
VCenter is upgraded. You can access the VCenter appliance
