NSX-T Data Center 2.4 Management and Control Plane agents



As in the previous article I have illustrated about the NSX-T DC 2.4 management plane and Central control plane which is now conversed into one nsx manager node.





MPA (Management Plane Agent): This agent is located on each transport node which communicate with the NSX manager


NETCPA:  It provides communication between central control plane and the hypervisor.


The management plane and the central control plane (CCP) run on same virtual appliance but they perform different functionality and will cover about they technical aspects below.


The NSX cluster can scale to max of 3 NSX manager nodes run on the management and CCP.




Communication process


The nsx-mpa agent on transport node get communicated with NSX manager over Rabbitmq channel which is on port 5671


Now, the CCP communicate with transport node through nsx-proxy through port 1235


The task of NSX manager is to push the config to the CCP. The CCP configures the dataplane through nsx-proxy, which is one of the component of LCP (Local control plane)

Changing the FQDN of the vCenter appliance (VCSA)

This article states how to change the system name or the FQDN of the vCenter appliance 6.x You may not find any way to change the FQDN from the vCenter GUI either from VAMI page of from webclient as the option to change the hostname always be greyed out. Now the option left is from the command line of VCSA appliance. Below steps will make it possible to change the FQDN of the VCSA from the command line. Access the VCSA from console or from Putty session. Login with root permission Use above command in the command prompt of VCSA : /opt/vmware/share/vami/vami_config_net Opt for option 3 (Hostname) Change the hostname to new name Reboot the VCSA appliance.   After reboot you will be successfully manage to change the FQDN of the VCSA . Note: Above step is unsupported by VMware and may impact your SSL certificate and face problem while logging to vSphere Web Client. If you are using self-signed certificate, you can regenerate the certificate with the

Unable to poweron the VM. (Failed to lock the file)

I have encountered may issues like where after some upgrade or migration we were unable to power on the VM. Figure 1 An error was received from the ESX host while powering on VM HSSVSQL01. Failed to start the virtual machine. Cannot open the disk '/vmfs/volumes/578d835c-18b2c97a-9b0d-0025b5f13920/SAMPLE1_cloud/000000.vmdk' or one of the snapshot disks it depends on. Failed to lock the file In above Figure:1, where while powering on the VM, its prompt for an error. Well, there are several reason for where the VM unable to poweron and you can find many article on this. Here in this article we will discuss to resolve this issue. Please use below step to resolve the disk lock issue  C hecked that VM is running on snapshot if its getting error " VM Consolidation required". Checked the snapshot manager if its showing any snapshot. If yes, try to delete the  snapshot. Verified the same from Esxi cl

Collecting Logs from NSX-T Edge nodes using CLI

  This article explains how to extract the logs from NSX-T Edge nodes from CLI. Let's view the steps involved: 1) Login to NSX-T  Edge node using CLI from admin credentials. 2) Use of  " get support-bundle " for Log extraction. get support-bundle command will extract the complete logs from NSX-T manager/Edge nodes. nsx-manager-1> get support-bundle file support-bundle.tgz 3) Last step is to us e of " copy file support-bundle.tgz url " command. copy file will forward your collected logs from the NSX-T manager to the destination(URL) host from where you can download the logs. copy file support.bundle.tgz url scp://root@192.168.11.15/tmp Here, the URL specified is the ESXi host ( 192.168.11.15) under /tmp partition where logs will be copied and from there one can extract it for further log review.
